Latin UNUS and the discourse properties of unity cardinals

Keywords: UNUS, unity cardinals, Vulgate, discourse, grammaticalization Résumé UNUS, cardinaux d'unité, Vulgate, discours, grammaticalisation

This article investigates the discourse behaviour of Latin unus ('one') in the Vulgate, in order to better understand the starting point of the grammaticalization process ultimately leading to an indefinite article. To this end, I will study unity cardinals in general, focusing particularly on English one. Empirically, it will be shown that unus behaved like a unity cardinal in late Latin, without showing any clear sign of ongoing grammaticalization towards an indefinite article. I will try to explain the discursive behaviour of unity cardinals with reference to antipresuppositions, within the framework of the game of same and different. Finally, I will sketch how the results fit within the general picture of the incipient grammaticalization of indefinite articles, by providing an account of so far unexplained scope phenomena.

I had the opportunity to present previous versions of this article at workshops at the universities of Paris 7 and Paris 8, and at the 2016 conference on Formal Diachronic Semantics in Konstanz, and I would like to thank the organizers and the audience for their helpful feedback. I would particularly like to thank Claire Beyssade, who convinced me to abandon my initial approach. I am also extremely grateful for the remarks and criticisms of the anonymous reviewers and the editors of this issue, which have allowed me to improve this article considerably. Igor Yanovich deserves special credit for his patience and never-ending efforts to bring the article into a publishable state. Finally, Heather Newell and Yannick Morin did a great job editing the final paper. All remaining errors and omissions are mine alone. This article is dedicated to the memory of Helmut Häusle.

INTRODUCTION

The present article provides a study of the Latin unity cardinal unus, which is the diachronic source of indefinite articles in Romance languages. I will focus mainly on its behaviour in discourse in Jerome's Vulgate (late 4 th century CE). My main empirical claim will be made in section 2, where I will show that unus had not yet acquired non-cardinal uses, and that all uses of unus are attested for the unity cardinal one in contemporary English. This claim argues against the proposal that the first clear attestations of indefinite article uses appeared in the Vulgate (claimed notably by Coleman 1991).

In section 3, I propose a formal semantic analysis of unity cardinals, and also provide an account of how their distribution is impacted by their potential alternatives (bare nouns in Latin, the indefinite article in English), based on previous work by Grønn and Saebø (2012). The aim of this section is to drive home the idea that the distribution of a linguistic item does not only depend on its intrinsic meaning and properties, but also on the meanings and properties of alternatives a speaker might choose.

Based on this, I will provide in section 4 a tentative account of the first steps of grammaticalization of indefinite articles. The main claim here is that scope phenomena that have been observed in the grammaticalization literature can be explained as being motivated by Horn's division of pragmatic labor between bare singulars and NPs modified by unity cardinals, and that in earlier stages of development the marked unity cardinal is used for marked semantic (and, notably, scope) configurations.

From unity cardinals to indefinite articles

We know that unity cardinals (i.e., cardinals expressing the number 1, e.g., English one) are one of the diachronic sources of indefinite articles (see Kuteva et al. 2019: 299ff.). There is a also a great wealth of literature in formal (and other) semantics on the indefinite article, from many differing perspectives and in different frameworks (see, among many others, Heim 1988, Hawkins 1991, Kamp and Reyle 1993, Reinhart 1997, Brasoveanu and Farkas 2011, Steedman 2012, Grønn and Saebø 2012). Therefore, we have a comparatively good understanding of one stage in the grammaticalization process. There is also a good amount of literature on the direction of change for a few language families (for instance, in Romance, see, e.g., Carlier 2001 2013, Pozas Loyo 2010)), and we thus have a good idea of the general direction of change. However, as far as I am aware, there has been a rather generalized lack of interest in the meaning and behaviour of the diachronic origin of these indefinite articles (but see Dahl 1985 for an exception to this rule). Therefore, we unfortunately know very little about the behaviour that is to be expected from a unity cardinal. Without a good understanding of the starting point, we cannot hope to grasp the overall development of indefinite articles, and may even fail to discern what is new behaviour for them at any given point in time. Furthermore, the fact that a more recent point on the developmental path is so much better understood than its origin may introduce a teleological bias in the review of the data. The main aim of this article is therefore to show that the discourse behaviour of unity cardinals is far from trivial, and that (1) John drank one bottle of beer.

The received standard-model of the grammaticalization of indefinite articles is provided by Heine (1997: 72ff.), based on earlier work by Givón (1981). It proposes a five-stage framework of the process, which is depicted in (2).

( The different initial stages (1-4) are mainly distinguished by their discourse (and scopal) behaviour, whereas in later stages (4-5) the disappearance of selectional restrictions regarding the modified noun also come into play. English 'one' (as seen in ( 1)) is a typical representative of the numeral in stage 1. Heine (1997: 72) characterizes the 'presentative marker' stage 2 as follows:

This stage is reached when the article introduces a new participant presumed to be unknown to the hearer and this participant is taken up as definite in subsequent discourse […] Stage 2 uses would correspond to determiners which appear to introduce important characters at the beginning of a story, as in (3), but do not appear systematically with secondary characters, or in contexts of the specific use of a noun phrase.

(3)

Once upon a time, there was a king … Heine (1997: 72) insists on the importance of subsequent mentions following the use of the element introduced by one. Furthermore, presentatives have obligatorily wide scope, and narrow scope behaviour does not resurface until much later (in stage 4). A stage 3 indefinite article is only employed to introduce specific uses of a noun (see (4a)), but does not appear in non-specific uses (see (4b)).

(4) Yesterday, I met an opera singer … a. …namely Rolando Villazón. b. …but I have no idea who that was.

English a(n) is a stage 4 indefinite article, since it can be used in both specific and non-specific contexts, but is restricted to singular count nouns, and cannot combine with plural count nouns or singular mass nouns, as is illustrated in (5). A full stage 5 indefinite article would be acceptable in all three of these contexts.

( As far as I am aware, researchers in the grammaticalization tradition generally seem to have taken the cardinal stage to be unproblematic; 1 Heine (1997: 72), for instance, devotes only 5 lines to stage 1 of the process. As I will try to show in this article, since both discourse and scopal behaviour of these forms is extremely important, we have to thoroughly investigate the behaviour of unity cardinals in these contexts.

One of the puzzles this received grammaticalization theory poses in the context of the development of scopal behaviour is that it assumes that aspects of the scope behaviour of the cardinal simply disappear in stages 2-3, and reappear at stage 4. This contrasts with hypotheses like the one in Pozas Loyo (2010), which assumes that there is not much meaning change involved between a unity cardinal and indefinite articles, and that changes primarily concern frequency of use. More generally, in Heine's received grammaticalization-theory plot of the evolution of indefinite articles, there is no explicit link between known meaning components of the cardinal, and stages in the model. Consider ( 6): (6) Every donkey ate one carrot.

In the most probable reading of ( 6), one carrot takes narrow scope with respect to every donkey, so taking wide scope is not intrinsically linked to the semantics of the unity cardinal. In Russian, an unaccented cardinal has precisely this restriction on wide-scope readings (see Heine 1997: 72), while accentuated cardinals can appear with narrow scope. 2 Of interest here is that it is uneconomical to assume that narrow-scope readings systematically disappear and reappear in the grammaticalization process of indefinite articles, and the different choices that speakers make with regards to the scope of unity cardinals needs to be explained.

Here I establish a more solid baseline for what can be expected from a unity cardinal by investigating the discourse behaviour of English one, and seeing how it can be used to explain the discourse behaviour of Latin unus. The general idea is that -since unus is a less economical form than a bare nominal in Latin (or the indefinite article in English) -its presence must somehow be motivated. To this end, I will integrate a formal characterization of unity cardinals into the framework of Grønn and Saebø (2012). Based on this investigation, I will then take a glance at the developmental stages in the rise of indefinite articles, and how they can be explained.

I have chosen the Vulgate 3 (a translation of the Bible by St. Jerome, ≈ 347-420 CE, commissioned by Pope Damasus in 382), because it contains certain uses of unus N 4 that have been claimed to be 'innovative', in the sense that they look suspiciously like 1 The exceptions to this lack of interest in unity cardinals come mainly from formalist traditions, and principally investigate the morphosyntax of unity cardinals (see Borer 2005, Barbiers 2005 2007). In the present article, morphology and morphosyntax will not be considered.

2 As pointed out by Igor Yanovich, one can interpret this in the sense that the unaccented cardinal is no longer a strict cardinal.

3 I am aware that the Vulgate as a translated and sacred text is at least potentially problematic; please refer to the Note in section 5 for an assessment of potential pitfalls. 4 In this article, I will deal only with the adnominal use of unus. It also has pronominal uses -just like English one. Una ancilla in (7) introduces a new discourse participant, and is generally translated by the indefinite article in English versions of the Bible, rather than a unity cardinal (which would sound odd here). As we will see below in (13), however, (7) can be explained (away) as a standard cardinal use of unus.

However, before being able to tackle the issue in Latin, we will need to investigate uses of the unity cardinal one in English, in order to get a better understanding of how these expressions are used in discourse. While the English article system is clearly different from that of late Latin, this will provide us with a baseline against which 'grammatically advanced' uses of unity cardinals can be evaluated.

Unity cardinals in discourse: a preliminary look at English one

The present section is not meant to provide an exhaustive description of the discursive uses of one in English. Its purpose is merely to describe the basic pattern in order to better understand the facts in the Vulgate. I have chosen English one as a blueprint for establishing the discourse-semantic meaning of unus because in English, the unity cardinal one is morphologically clearly distinct from the indefinite article a (contrary to, e.g., Romance languages, or written standard German). Furthermore, one would expect one to be unaffected by any ongoing process of grammaticalization, since the presence of the indefinite article a should block it. I will come back to a more precise characterization of the constraints on the use of one in section 3.

According to standard dynamic semantics (e.g., Kamp and Reyle 1993), indefinite articles introduce new discourse participants. This is also the case for many uses of one in English. A first use, which I will refer to as the partitive use, introduces a new referent into the discourse, which is part of a larger entity previously introduced into the discourse. Consider (8). ( 8)

We saw a lot of cows I . [One cow] i∈I appeared to be looking at me with an attitude like, "What? You never saw a cow before?" internet example

The entity denoted by one cow in ( 8) is in a sense discourse new. Yet, it also is a part of a plural discourse referent already introduced (a lot of cows).

With an indefinite article, a partitive reading is difficult to get:

(9)
We saw a lot of cows I . #[A cow] i∈I appeared to be looking at me with an attitude.

One is also often used in contrastive contexts, either when there is a contrast to another token of the same kind (see (10a)), or when there is a contrast between two cardinals (see (10b), which I will refer to as numeral contrast): In both contexts, the indefinite article would be slightly strange. 5 Notice, however, that the indefinite article does not generally exclude partitive interpretations; they are only not very salient in most contexts.

(11) That wasn't A reason I left Pittsburgh, that was THE reason. 6 However, as shown by ( 9), the indefinite article cannot refer back as a partitive anaphora to a close and explicitly given plural antecedent. The Latin determiner system is not identical to the one in contemporary English (English has fully grammaticalized indefinite and definite articles, whereas Latin has bare noun (phrases) and a rather limited use of ille -which is the ancestor of most Romance definite articles). However, as we will see, this preliminary investigation gives us a useful blueprint for what uses we should be looking at in Latin.

Generally, the point is that the more an occurrence of unus looks inexplicable in terms of a unity cardinal, the more we will be tempted to classify it as an indefinite article. Therefore, knowing what to expect is crucial.

The remainder of the article is structured as follows: based on our summary description of English one, we will look in more detail at uses of unus in the Vulgate that seem to be problematic. Then, we will go back to English in order to better characterize the meaning of unity cardinals in terms of their antipresuppositions (see Percus 2006, Sauerland 2008, Grønn and Saebø 2012, Amsili and Beyssade 2016), and apply these ideas to Latin. A section describing the changes required for a unity cardinal to become an indefinite article concludes the article.

A DETAILED LOOK AT 'INNOVATIVE' USES OF ADNOMINAL UNUS IN THE

VULGATE In this section I will take a detailed look at instances of adnominal uses of unus which appear at first sight to be indefinite articles, that is, where there are no motivations for the presence of a unity cardinal in the immediate vicinity. 7 Each time, I will try to 5 The two editors of the CNJ did not agree on the infelicity of the indefinite article in (10b). However, I still think that both sentences are slightly odd if they are planned in advance as setting up an opposition between the two cows, or between Peter and Fred. See also footnote 22 on the importance of rhetorical relations like CONTRAST.

6 Example cited from Abbott (2004: 125). 7 Through a corpus search, all instances of unus in the Vulgate were extracted, examined, and annotated for features relevant for the appearance of the unity cardinal (e.g., partitivity, contrast elements, etc.), as well as syntactic features (position with respect to the noun, etc.). This allowed me to isolate cases where the motivation for the presence of unus was not obvious. I will not be able to go into all such instances here; I will try, however, to show that there are rather typical instances which do seem like unity cardinals, based on our use cases of one, whereas others are more problematic. identify elements that may have motivated the use of unus. Since the earliest stages of grammaticalization of the indefinite article are assumed to involve major characters in a story, 8 I will also comment on the respective importance of the character. Most uses of unus in the Vulgate are entirely unproblematic, given an analysis as a cardinal: they are either used in contrastive contexts (see (12a)), or in partitive contexts like (12b-c). In what follows, I will look at uses of unus that are both adnominal and which I have classified as introducing a new discourse participant, and therefore, might be instances of an indefinite article. 10 Often, in looking at the larger context, the motivation of the use of unus will become clear.

8 See Heine (1997: 72): "An early stage II situation would obtain in a language where the article is confined to the beginning of a narrative discourse-for instance, where the main participants are introduced with the presentative article at the beginning of the tale." [emphasis mine].

9 A general note on the rendering of Bible verses: All English translations of Bible verses have been taken from the Douay-Rheims English version, and cited according to http://www. latinvulgate.com. For different Greek versions of the Bible, I have used Aland et al. (2012) and Hodges and Farstad (1985). The version of the Vulgate I used is the one from the Bibliotheca Augustana (see Harsch 1996-). If the text from the Bible is sufficiently short, I have provided glosses; for longer passages, where glossing is not practical, I only provide the translation. It turns out that (13) -instead of being a clear instance of a (proto-) indefinite article -is clearly an instance of a contrastive use: una ancilla as opposed to alia. However, the distance between these two elements is abnormal (viewed from the perspective of contemporary English): 11 there are two instances of direct speech between the occurrences of unus and its contrasting alius, as well as their introductory formulae. Furthermore, una ancilla in ( 13) is quite close to a throw-away referent: 12 it refers to an extremely secondary character, and is not taken up again. In verse 53, we have a discourse-new woman, reinforced with ecce. However, this refers back as a partitive to the plural discourse referent mulieres, in verse 51. Therefore, this is an instance of the partitive case. And once again, we have a throw-away referent: this particular referent is not taken up again. 13

Slightly less clear cases

The next type of use resembles at first glance the examples we have seen before, although upon closer scrutiny, they may not be identical.

A partitive instance of such a case can be illustrated by the following sequence from Mark 12:38-44, which is the last parable in a lengthy sequence of parables. The main point here is to caution against the scribes who "eat" the widows out of house and home -and very conveniently, in Mark 12:42, a widow comes by, thereby driving home Jesus's point.

( 13 Unless one considers a femina in verse 54 to be anaphoric to una mulier. However, what king Abimelech takes to be shameful here is not that the action of that particular woman might cost him his life: it is to be killed by any women. Therefore, I do not think that femina should be interpreted as being anaphoric to mulier. i i "unus-resubmitted-edited_GS" -2020/6/24 -8:05 -page 10 -#10

And Jesus sitting over against the treasury, beheld how the people cast money into the treasury. And many that were rich cast in much. 42 And there came a certain poor widow: and she cast in two mites, which make a farthing. 43 And calling his disciples together, he saith to them: Amen I say to you, this poor widow hath cast in more than all they who have cast into the treasury. 44 For all they did cast in of their abundance; but she of her want cast in all she had, even her whole living.

At first glance, this seems to be exactly the same as in ( 14): una vidua pauper has a plural antecedent, namely viduarum. However, while one cannot exclude that the occurrence of viduarum in verse 40 is to be taken referentially, it does not seem to be necessary to me (it might be a metaphor). If it is not taken referentially, the case for a partitive use is undermined.

The referent introduced by una vidua is developed a little bit; but once again, this is not an individual who as such has any importance in the gospel. The widow is used to make a point against the religious establishment of the times. The sequence where the widow appears is outside the warning against the scribes; yet she illustrates the point so well that it has to be taken to be a part of that sequence, and is therefore detached from the main story line.

Besides such (quasi?-)partitives, there are also cases that look like contrastive uses, but which are slightly different from what we have seen so far. In prototypical cases of contrast, we have a repetition of the predicate, or an anaphora to the same predicate. This, however, is not always the case. Let us consider Matthew 8:19-22. The wider context is the following: Jesus has been laboring through a long day of miracleworking and being solicited by all kinds of people. In the preceding or subsequent context, there is no mention of another scribe or scribes. Therefore, a partitive use or a contrast with respect to another scribe can be ruled out here. However, there is a contrast with alius, even though they do not share the same predicate (scribe vs. disciple). So, this particular instance of unus appears unexpected. However, by declaring his will to follow Jesus, the scribe becomes a disciple of Jesus. The whole sequence would be perfectly as expected if it were analyzed as a pronominal unus with scriba as apposition -some guy, a scribe -which, given the near-total lack of punctuation, cannot be ruled out. Once again, the scribe is a secondary character, and certainly no protagonist of the gospel, ruling out an analysis as a stage 2 presentative marker.

Summing up, we have discussed here cases that do not correspond perfectly to what we have come to expect from English one: i) the distance between the motivating contrast or partitive element may be greater than what is usual today in English, even though the motivating element itself is in principle clear; ii) the motivating element may not be completely obvious in the text, or may depend partially on contextual assumptions. However, given some leeway, I have tried to show that these uses are not that far removed, or can be interpreted in a way that maximizes their conformity with "standard" cardinals.

However, there are cases for which such a strategy seems to have its limits, which we will turn to now.

Cases without textual antecedent or contrastive element

While many cases seem unproblematic based on the assumed discursive effects of unus, some other uses are more difficult to reconcile with the effects we hitherto discussed -notably those that appear at the very beginning of a discourse. Such uses are interesting because they correspond to the prototypical stage 2 uses of Heine (1997). 14 One such case is from 1 Samuel 1:1-3.

( There are no other men mentioned in the text in proximity proximity to vir unus (one man), apart from Ophni and Phinees, but these are classified as filii Heli -sons of Heli). There are, however, a few other numbered elements: two wives; two sons of Heli, which might legitimate an interpretation as a numeral contrast. Elcana is an important character in this story, because he is the father of Samuel. But what may have triggered the use of UNUS here? We are fortunate enough to have a near minimal pair in Job 1:1-3.

(18) 14 As was pointed out by one of the anonymous reviewers, such uses of the cardinal are possible in contemporary English as well: There was (once) one man… 1 There was a man in the land of Hus, whose name was Job, and that man was simple and upright, and fearing God, and avoiding evil. 2 And there were born to him seven sons and three daughters. 3 And his possession was seven thousand sheep, and three thousand camels, and five hundred yoke of oxen, and five hundred she asses, and a family exceedingly great: and this man was great among all the people of the east.

The only relevant difference concerning the entities introduced at the very beginning of the text is that Job is the main character of the book, whereas Elcana is secondary -even though the book starts with him: he is the protagonist's father. Other than that, there does not seem to be much difference here: it seems extremely unlikely that Job and Elcana were the only men in Hus and Ramathaimsophim, respectively; and in both cases, there are many numerical expressions in the immediate vicinity, which might license a reading of numeral contrast (although not with the same predicate). What one can probably deduce from this contrast is that unus was possible in such circumstances, without being obligatory.

Some might be tempted to dismiss these two cases, since they come from the Old Testament, and therefore could be argued to reflect a use of the Hebrew unity cardinal exad ('one'), or its absence.

However, apart from the idea defended in this article that one should read the Vulgate as a coherent text, there are also empirical reasons why such cases cannot be dismissed. Indeed, there are occurrences in the New Testament where unus appears without a clear antecedent, and therefore, highlight the same problem. Consider Matthew 9:18 (with some context). Here, Jesus returns to his hometown, performing miracles. This attracts considerable attention by all sorts of people, and among the categories introduced into discourse before these verses figure scribes, tax collectors, sinners and Pharisees. There is nothing in the verses following this passage that could motivate the presence of unus. Therefore, much hinges on the interpretation of princeps: the New International Version and other translations render this as leader of a synagoguewhich should then be a Pharisee, since the Pharisees are the religious movement historically related to synagogues. In this case, it would be a straightforward partitive use. Be that as it may, this is once again a secondary character, and therefore, not one whose textual importance would be expected to be underlined by (what might be) a stage 2 indefinite article.

The most problematic example for a simple adaptation of the discourse behaviour of English one seems to be the following instance from Matthew 21:19 (once again from the New Testament), where unus lacks an antecedent, as well as a contrast element:

( It is not immediately obvious what motivates the occurrence of unus here. A partitive is implausible, since the context strongly suggests that this tree was the only fruit tree in the vicinity. There is no contrastive element, either. As far as I have seen, most English translations seem to favor an interpretation along the lines of arbitrariness or lack of importance. However, a paraphrase along "(only) a single" might be fitting here. Such a reading is not easily expressed in contemporary English with the unity cardinal alone, but the use-case can be interpreted as a rather straightforward extension of a cardinal use. Notice once again that the identity of the fig tree is completely unimportant; it is merely a pretext for a parable. Therefore, it cannot be taken to be an early stage 2 presentative indefinite article. The context in Matthew 21:19 is also one where an English weak some would be an appropriate translation, as far as it can convey arbitrariness and lack of importance.

Let us sum up what we have seen so far. In the Vulgate, the vast majority of the occurrences of unus are straightforward cardinal uses; some uses fit into the familiar i i "unus-resubmitted-edited_GS" -2020/6/24 -8:05 -page 14 -#14 And even if Heine's model should not be entirely appropriate, given the examples discussed and their similarity to uses of English one, there does not seem to be a compelling reason to assume that unus is anything other or anything more than a unity cardinal in the Vulgate.

AN EXPLICIT TREATMENT OF THE DISCURSIVE BEHAVIOUR OF UNITY-CARDINALS

In section 1.2 I gave a brief description of a few salient uses of one in English, namely partitive uses, and contrastive uses, and we have also seen that many uses in the Vulgate that look at first sight like indefinite articles can be viewed as variations of these uses, if considered in a larger context. The question is how these uses can be accounted for from a formal point of view.

I will argue that unity cardinals trigger antipresuppositions (also known as implicated presuppositions, see Percus 2006, Sauerland 2008), extending in particular the ideas of Grønn and Saebø (2012) and Amsili and Beyssade (2016). I will argue that generally, projective content is a promising way of making sense of the discursive behaviour of these forms.

I will sketch the basic idea for English, and then try to carry it over to Late Latin.

Extending the game of same and different: projective content and antipresuppositions

My account of the meaning of one will extend the work on antipresuppositions by Grønn and Saebø (2012) on the use of indefinites, and build also on some extensions of their work done by Amsili and Beyssade (2016). I will first present their basic ideas, and then integrate one into the framework (which I will assume to be a valid representation also for other unity cardinals, like unus).

The basic intuition of this literature concerns the "novelty condition" or effect of non-uniqueness of indefinite articles. This phenomenon is illustrated by the following example, due to Heim (1991: 515f.): Whereas the definite article in (21a) refers to the pianist of the Beaux-Arts Trio, a pianist in (21b) suggests that the pianist was not the one of the trio. The issue with this condition is that it does not seem to hold in all contexts. Antipresupposition approaches to indefinites argue that this is not a basic, semantic feature of the meaning of indefinites, but arises from the fact that it competes in many contexts with a definite article, which contains an explicit presupposition that the entity talked about is already in the common ground (and unique, when we talk about a singular definite). 15 Grønn and Saebø (2012: 79) define an antipresupposition as follows:

(22) Antipresupposition When you have a choice between two forms α and β differing only in a presupposition π, triggered by α but not by β, if the contexts supports π, you are to choose α. Thus, when you use β, this will signal the opposite: π is not supported by the context.

I will use the following representations of indefinite and definite articles based on Grønn and Saebø (2012) and Amsili and Beyssade (2016) 16 , using a flat DRT notation based on Sauerland (2008), where the numerator indicates the presupposition, and the denominator the assertive content:

(23) a → λPλQλw | x|P w (x), Q w (x) (24) the → λPλQλw z|P w (z), card(P w ) = 1 x|P w (x), Q w (x), x = z
The indefinite article is assumed to contain no presupposition, whereas the definite contains the presupposition that there is already an entity satisfying the same predicate P in the context, and that the cardinality of the predicate in the context corresponds to 1. Furthermore, the definite article imposes in its assertive content an identity condition on the new discourse referent, making it identical to the already present entity, which is not the case for an indefinite.

(i) the → λPλQλw z|P w (z) x|P w (x), Q w (x), x = z
Grønn and Saebø do not deal with plural definites in their article, but once they are taken into consideration as alternatives, it will be necessary to include some sort of unicity presupposition in order to account for presupposition failures when trying to refer to a plural antecedent with a singular definite DP. Amsili and Beyssade (2016) provide a formalization that meets this objective.

i i "unus-resubmitted-edited_GS" -2020/6/24 -8:05 -page 16 -#16

i i i i i i 16 SCHADEN
What these representations ensure is that a and the form a Horn-scale, where the is a stronger alternative than a -which is indeed desirable, given their use in contexts like not just a N, but the N:

(25)
These girls are looking for not just a guy, but the guy.

COCA Corpus

Therefore, the argument goes, if a is in competition with the -which is not the case in all contexts -, one will get antipresuppositions of novelty and non-uniqueness. Grønn and Saebø (2012) propose that another element may impact the distribution of the indefinite article, namely another, represented as in (26). 17 (26) another → λPλQλw z|P w (z)

x|P w (x), Q w (x), x = z
Another contains a presupposition that there is already an entity of predicate P in the context, and asserts that the new discourse referent is different from that entity. Once again, another is strictly more informative than a, and so in cases where a is in competition with another, the use of a should license the inference that the newly introduced entity is identical to the one already existing in the common ground. Grønn and Saebø (2012: 85) argue that in cases where the speaker is assumed to have sufficient relevant knowledge, and if both the and another are competitors, the use of the indefinite article is infelicitous.

Let us now introduce one into this comparative endeavour, this game of same and different. I will assume the following representation for one:

(27) one → λPλQλw | x|P w (x), Q w (x), card(P w ∩ Q w ) = 1
The representation in ( 27) thus assumes that one has no presuppositions, and that it contains a cardinality condition (card(P w ∩ Q w ) = 1), which is the only element distinguishing it from the indefinite article.

Let us walk through this, and justify some aspects of this formalization. Notice first, that a, the, and one (as well as another) assert the existence of an entity of type P:

(28) a. John saw the rabbit. b. John saw a rabbit. c. John saw one rabbit.

All of (28) entail that there exists a rabbit. And (28a) and ( 28c) have a uniqueness entailment: there is only one rabbit (such that they saw it). This is the familiar uniqueness-presupposition in the case of (28a), but in the case of (28c), this seems to work differently: it is compatible without any problem with the existence of several rabbits in the context (see (29a) vs. (29b)).

17 Amsili and Beyssade (2016) propose a compositional account of another (as a(n) + other) and the other, but I will not concern myself with this. Since the according to (24) requires unicity only with respect to its nominal predicate (here rabbit), (29b) is predicted to fail because of the contradiction with the presupposition; (29a) is predicted to be felicitous because unicity here depends not only on being a rabbit, but also on being seen by John.

Concerning the cardinality condition, Crisma (2015: 146) observed that one does not behave like other cardinals, which have a "soft", implicated upper boundary.

(30) a. John saw two rabbits; in fact, maybe he even saw three. b. John saw one rabbit; #in fact, maybe he even saw two. c. John saw a rabbit; in fact, maybe he even saw two.

One explanation for the pattern in ( 30) could be that one necessarily has a focus on the unity cardinal, since it has an (unfocused) a clitic alternative (namely the indefinite article). However, this does not seem to be the whole story, since in embedded contexts, the focus may fall on either 'one' or on the noun:

(31) a. I'm sure that John saw [ONE] F rabbit; #in fact he maybe even saw two. b. I'm sure that John saw one [RABBIT] F ; #in fact he maybe even saw two.

(31a) is infelicitous, as expected, but even (31b) does not allow for the continuation, even though the focus sensitivity operator is associated with the common noun here. 18 Notice that the definite article seems to behave more like the indefinite article than the unity cardinal, as it allows the continuation in (32). It does not seem to block reference to elements that are not (as of yet) in the common ground the way 'one' does.:

(32) John saw the rabbit; in fact, maybe he even saw two rabbits.

Furthermore, even though according to this formalization, one should entail a, there is probably no scale associated with the opposition between a and one, as is indicated by the infelicity of ( 33):

(33) ?*These girls are looking for not just a guy, but one guy. 18 As pointed out by Igor Yanovich (p.c.), (31b) might be infelicitous simply because the contrast given in the second clause does not match the focus structure in the first clause. However, if the focus on rabbit is motivated by a contrast with the preceding context, the issue still remains:

(i) a. Wait a minute -did John see one rabbit or one naked mole-rat? b. I'm sure that John saw one [RABBIT] F ; #in fact he maybe even saw two. As has been known at least since Hawkins (1991), in contexts like (34a), with an inalienable possession below have, definite articles are infelicitous, as is illustrated in (34b). Therefore, they are no alternatives here. However, even though humans prototypically have unique noses, one still cannot say so and use the unity cardinal when talking about inalienable possession. Even adding a contrastive element (i.e., Jill's nose, as in (34d)) does not make things better. Intuitively, what makes (34c) strange is that it suggests that John might have more than a single nose -which is not possible under cases of inalienable possession and standard human anatomy. This is probably best explained as follows: in using one where the indefinite would have been appropriate, the additional effort (or use of the less frequent item) must be somehow motivated (and this will thus give rise to a manner implicature). This motivation then makes scalar alternatives to one (that is, other cardinals) salient. Indeed, even though one does not seem to be on a scale with a, it is a member of scales involving cardinals, or imprecise cardinal expressions (like several, or many): The observation here is that, even though -according to the present formalization one should be able to form a semantic scale with a, it is not located at the same level of grammatical saliency in English as the definite and indefinite articles: one clearly is a second-tier determiner, which has much lower frequency than the articles. 19 Therefore, there is at least a frequency effect underlying (or influencing) the range of possible choices. 20 Let us now come back to the standard cases in which one is used in English, and consider first the partitive use. In such a context, we have a plural antecedent in the common ground, and we want to assert something with respect to a single entity out of this plural antecedent. Clearly, in such a case, the definite article is infelicitous, 19 According to the word count using all the books archived in Project Gutenberg given in http://1.1o1.in/semanticdepth/freq100000.pdf, the is the most frequent word in English, while a is the 5th most frequent. One is the 39th most common word in this corpus, and while all uses of the and a are determiner uses, one has pronominal and other non-determiner uses as well. 20 Geurts (2011) introduces the notion of the availability of alternatives. A much more frequent expression with overlapping meaning should count as available. 19 because its presupposition fails when combined with a singular, and the assertion fails when combined with a plural. The question is, how could we account for the infelicity of the indefinite article? Competition with another should not be an issue here, since the new entity is part of the given entity. Grønn and Saebø (2012: 86) suggest for a slightly different case (with a singular antecedent), that the indefinite is blocked because it is a clitic: with a plural N as antecedent, the singular N has to be deaccented (since it is given), and because the indefinite article is a clitic, it cannot receive an accent, either. Hence, a is blocked, and we need something that can be accented, and has a meaning that is similar enough. One is a possible candidate, and is therefore used instead of the indefinite. 21 Second, the same type of reasoning obtains when we have the familiar opposition of one (N) with another (N). In these cases as well, if the speaker wishes to mark contrast, the noun will be deaccented, since this contrast will not involve the (identical) predicate. Therefore, this situation requires a determiner which is not a clitic (which therefore excludes the articles the and a, whose accented versions can only be used metalinguistically). If the entity is not already discourse-old, one is then the only article that fits the bill. 22 Numeral contrast can also be explained by the assumed semantics, since one is the only one of the considered determiners which has a cardinality specification as an asserted content (contrary to the definite determiner, which may have a cardinality (i) X|P(X) z|P(z), Q(z), z ∈ X Notice that semantically, a is fully compatible with the context in (i); there is conflict in neither presupposition nor assertion. Because of presupposition failure, the singular definite article is no competitor; and if the competition were between the indefinite article and another, a should by antipresupposition have a non-novelty effect. And being singular and non-novel could only correspond to the partitive condition. But the fact is that the indefinite article is infelicitous in these contexts. Therefore, either the meaning assumed here for a is incorrect, or its infelicity is not related to its meaning, but to some other property. Given the quantity of literature on the indefinite article, it is more prudent to assume the latter.

Another strategy to explain the unavailability of the indefinite article would be to resort to a manner implicature arising from the competition between the unmarked bare singular, and the marked unity cardinal, and for contexts that would oppose the more frequent contexts of introducing a new discourse variable in an empty context, as opposed to the less frequent partitive contexts. A worked-out analysis along these lines will be proposed in Schaden (to appeara). 22 As has been noted by Beyssade (2017: 66f.), rhetorical relations also have an impact on the admissibility of anti-presupposition triggers (which may be related to intonational patterns: ENUMERATION, PARALLEL and CONTRAST all can be seen to involve contrastive topics). When the contrast is on the predicate as in (36c-d), the indefinite article is felicitous, even if the numbers are different. However, if the predicate is the same and the quantity different, the unity cardinal is obligatory, and the indefinite article infelicitous. This must be due to the contrastive stress on the determiners, which cannot be carried by a clitic like a. So, should this kind of reasoning be correct -which is a conservative extension of the work of Grønn and Saebø (2012) and Amsili and Beyssade (2016) -, the reason one is used in a number of contexts instead of the indefinite article is mainly because it can be accented, while still being sufficiently close in meaning to the article. Indeed, in many contexts, an indefinite article will also imply that there is no plural entity, which is why the additional meaning of one is not a handicap.

UNUS in Latin: Alternatives and effects

Let us now go back to the Vulgate. We have seen in section 2 that the patterns seen with with unus are close, though not completely identical, to what we observe in English. Assuming, furthermore, that the linguistic phenomenon distinguishing the use of the unity cardinal and the indefinite determiner has been correctly identified as antipresupposition, it is important to know what the alternatives to unus were in the Latin of the Vulgate. The major difference between English and Latin is that the latter had no articles, and that singular bare nouns covered the use cases of both definite and indefinite articles in contemporary English. This can be illustrated by example ( 14), repeated below as (37). ( 37 21 new, is however marked in current English by an indefinite, and the two subsequent occurrences by a definite article, as can be seen in the translation. Therefore, the major alternative to unus, given the assumption -as above -that unity cardinals have an existential entailment, was the singular bare form. Another possible competitor is ille N, which is the diachronic source of most of the definite articles in Romance.

What precise meaning should we assume for these entities? I suggest that the meaning of unus is identical to the meaning of one in English, and that the meaning of a bare singular corresponds to a NP with an indefinite article in English:

(38) unus = one → λPλQλw | x|P w (x), Q w (x), card(P w ∩ Q w ) = 1 (39) / 0 = a → λPλQλw | x|P w (x), Q w (x)
It is important to notice that semantically, the representation in ( 39) is perfectly compatible with both definite and indefinite uses as illustrated in (37); it merely does not require its uses to be one or the other.

I will justify the representations in ( 38)-( 39) shortly, but let me first say a word about ille. Ille, like unus, has pronominal and adnominal uses, and appears 1498 times in the New, and 3097 times in the Old Testament. Among these occurrences, 241 attestations in the New Testament, and 154 in the Old Testament, are adnominal. 23 Unus appears 298 times in the New Testament, and 723 times in the Old Testament, of which respectively 121 and 432 are adnominal. 24 While the global frequency of ille is therefore roughly four times higher than that of unus, their adnominal uses are comparatively frequent. I therefore do not take ille to be a direct competitor to the bare nominal option (as a definite determiner would be), but rather to still be a demonstrative (which may be a competitor in a few, very circumscribed cases). 25 I will therefore assume that in Latin a bare noun is always available and salient, and that the use of unus has to be understood with respect to such a background. The explanations for the use of unus in Latin are thus basically the same as what we have already given for one in English, with the difference that there is no dedicated definite determiner, and there are no articles in general. Let us walk this through for 23 The count has been established as follows: I extracted all verses containing ille, which I then tagged with treetagger (see Schmid 1994), using Marco Passarotti's Latin parameter file, via Laurent Pointal's treetaggerwrapper-library for python. I counted as adnominal all cases where a form of ille was congruent to a noun within a window of three words before and three words after ille. This method of counting overestimates adnominal uses at least slightly. 24 This count was done by hand, and is therefore more reliable than the count of ille. 25 If ille were a competitor to unus and/or the bare singular, this would influence the expected anti-presuppositions of unus and the bare singular, and, therefore, their respective distributions. This has undesirable effects especially for the bare singular, which would then be predicted not to appear in any case where ille is felicitous -which would therefore exclude many simili-definite uses. Once again, we have to assume that the noun must be deaccented in the partitive (since it is given), and that we have to attribute an accent somewhere in the DP. A non-existent determiner cannot be accented, but it is not problematic to accent the determiner in unus N. Similarly, in a case of numeral contrast, the singular case-ending of a noun cannot be accented.

In order to discuss a non-partitive use, let us look at an example where unus appears discourse-initially. Consider (40) -which, while not coming from the Vulgate, exemplifies the same late Christian Latin stratum. Why would anybody want to use unus in such a context? The reasoning might go as follows: assuming that the bare noun is used either for a reference to an entity already in the common ground, or some new entity to be introduced, it might be inappropriate in the context of a creed. In the context of a predominantly polytheistic society, having a unique, presupposed entity satisfying the predicate god is bound to fail. On the other hand, without an explicit unus, there would probably be a possibility of reading it in a simple, existential way: there is at least one God I believe in. This, however, would not be sufficiently distinctive with respect to followers of Mithra, Jupiter, Isis, etc., and therefore, the unity cardinal becomes necessary. 26 The basic findings of this section are the following: assuming that unity cardinals do not carry any presupposition, and come with a cardinality meaning (as I have proposed in ( 27)) can explain their distribution in Latin and English with the added proviso that unity cardinals can be stressed, contrary to clitic or null determiners. In extending the game of same and different of Grønn and Saebø (2012), unity determiners may be found where definite and indefinite articles, and another cannot: in cases of partitive reference, and in cases that rely on contrast on tokens satisfying the same predicate, or more generally, cases that stress differences in cardinality.

One final concern is the major difference between Latin unus and English one, namely the possible distance between the unity cardinal and the element that it either contrasts with or has a partitive anaphora with. I do not know to which factor this should be attributed. I can see at least two candidates: First, the prevalence of gender marking in Latin could narrow down the potential antecedents in a way that is more difficult for a language like English where gender is at best a covert category. Second, admissible distance might be correlated with the overall frequency of determiners: it is possible that in a language without determiners, entities that are used with one achieve much higher salience than the same entities in a language with fully obligatory determiners, such as English. Should the first hypothesis be correct, all other things being equal, the admissible distance in German should be higher than in English; the second hypothesis predicts that null-determiner languages in general 26 Notice that there are versions of the creed (namely the Apostles' Creed) which do not have unus -this is arguably because they presuppose the belief in some form of monotheism.

TOWARDS AN EXPLANATION OF THE FIRST STEPS IN GRAMMATICALIZATION

My basic assumption is that an indefinite article is a unity cardinal that is used very often (and eventually may become obligatory in some contexts). During this process of becoming obligatory, it may diverge in its form from the cardinal (which occurred in English, and some varieties of German, but not in Romance languages). Given these assumptions, three basic questions are in need of an answer: i) what meaning change does this increase in use require? ii) why should the rate of use of the unity cardinal increase?; and iii) how is this increase related to the phonetic erosion of the unity cardinal? 27 The important background to note is the following: under the assumptions we have made in this article, even though a unity cardinal comes with strictly more meaning than a bare form (or than an indefinite article, in languages that have one), given standard use cases for those forms, it will rarely be the case that the context makes the use of the cardinal inappropriate or even false. Most of the time, its use will constitute more signaling effort than is strictly necessary. Such cases of unclear motivation are attested in the use of unus vs. the bare version, as in (close-to) minimal pairs like the following: (41) a. latitudo width.NOM It should be clear that there is no truth-conditional difference between the two versions in (41); however, there does not seem anything fundamentally wrong with employing the unity cardinal. 28 On the other hand, there will also be few contexts which would require the meaning of a bare singular (or an indefinite article), as opposed to the meaning of the unity cardinal. For instance, there is nothing wrong in principle in using a unity cardinal in a predication context (although it has some effects we will discuss in section 4.2 below):

(42)
'Rampage' is one stupid ass movie. 29 27 This step is arguably optional, as illustrated by Romance languages. 28 One gets similar effects in measure phrases in contemporary English; in the COCA corpus (compiled by Davies 2008-), a search for an inch yields 4171 results, whereas one inch yields 471 hits.

29 This is the beginning of the (not entirely negative) review; there is no reference to other movies in the whole text. And sure enough, for all the bad things one might say about Rampage, i i "unus-resubmitted-edited_GS" -2020/6/24 -8:05 -page 24 -#24

i i i i i i 24 SCHADEN
Similarly, the existence of plural forms is not incompatible with a cardinal interpretation. Notice that many unity cardinals do allow for plurals (think of English ones), and that, if the semantics for unity cardinals proposed in Schaden (to appearb) is correct, there is indeed nothing in the meaning of a unity cardinal that would be intrinsically incompatible with pluralization. Therefore, the presence of a plural form of a unity cardinal is not ipso facto an indicator of a highly advanced indefinite article. 30 Thus, the major checks on the frequency of the unity cardinal are not the intrinsic meaning of the unity cardinal nor the contexts in which it appears, but rather speaker effort and the effect a speaker wants to obtain by choosing a more elaborate signal.

That being said, let us address the three questions.

Meaning change: weakening the hard upper bound

If the results of this article are to be trusted, one N is only distinct from the indefinite article by having a cardinality meaning attached to it, and it triggers antipresuppositions which make it apt to appear in partitive and contrastive environments, which depend crucially on its not being a clitic. Obviously, both the antipresuppositions and the cardinality component no longer arise in the same way with an indefinite article like the contemporary English a. Remember also from (30) that the cardinal meaning of unity cardinals is special in that it has a hard upper bound, and not a soft upper bound like all other cardinals. Let us fast forward a few centuries. Carlier (2001 2013) observes that Latin unus in a restrictive sense (that is, uses roughly conveying 'a single N') is translated in Old French generally by uns, whereas from the Middle French period on, there generally is a additional restriction (≈ 'only') added to it: This change in translation is clearly significant, but there are two possible ways to interpret it. Carlier (2013: 47) takes additional restrictors to indicate that un is no longer it is a movie, and its cardinality is one. Source: http://redcarpetcrash.com/movie-reviewrampage-is-a-disaster-for-better-and-worse/, retrieved on 10/10/2018. 30 It has been observed that in languages like French or Spanish (see Carlier 2013, Pozas Loyo 2010), plural forms of unus appear relatively early, much earlier than predicted by the scale by Heine, even though it is not obvious how this fact should be interpreted. 31 The examples in (43) are taken, with their glosses, from Carlier (2013: 47). The Latin original is from Cicero, De Inventione II, 64. The translation in (43b) is from J. d'Antioch (1282, LI), whereas (43c) comes from a 20 th century translation by Bornecque. a cardinal. Her reasoning goes as follows: in Old French, where the numeral value was still dominant, the translators felt no need to add a restriction, whereas in more recent varieties of French, where we can assume un to be an indefinite article, there is a need for adding such a restriction, in order to obtain a cardinality interpretation. Therefore, the presence of a restriction is an indicator of a loss of cardinality status and meaning, in a two-step process from cardinal to indefinite article. However, this does not necessarily follow. A second, and by far more conservative interpretation of the same facts (under the assumption of a gradual transition from "hard upper bound cardinal" to indefinite article) is that the rising frequency of restrictors simply indicates that the upper bound constraint was softened, and that the unity cardinal aligned with other cardinals (thus, that the uses of one vs. only one exactly parallels, e.g., the use of two vs. only two), and does not indicate a complete loss of cardinal status.

The basic issue here is that we have (at least) a three-step transition, from hard upper bound cardinal to soft upper bound cardinal, and then from soft upper bound cardinal to indefinite article. How can we explain the disappearance of the hard upper bound? Unless one assumes that unity cardinals are fundamentally different from all other cardinals, this is likely due to an antipresupposition in languages which have a singular-plural system, since the unity cardinal has a competitor in the singular bare noun or indefinite article which all other cardinals lack. 32 Therefore, if the unity cardinal is chosen over the default (bare or indefinite article), which also signals a singular entity, this may signal higher confidence, and the 'exactly' interpretation will arise, and the hard upper bound will be derived.

However, once the use of the cardinal becomes more frequent, and a hearer no longer expects the of use of the alternative form, the hard upper bound disappears, and the unity cardinal aligns with other cardinals in obtaining a soft upper bound.

The Increase in frequency

Now, let us get back to the first question: why should the frequency of use of a unity cardinal rise in the first place?

When looking at examples like (41b) or (42), it seems probable that emphasis has a role to play: even in the absence of a clear truth-conditional difference, if there is emphasis, the unity cardinal is used; without emphasis, the alternative (bare noun or indefinite article) is used. It may appear that the notion of emphasis is a poor choice underlying a formal model of language change, but Ahern and Clark (2017) have already worked out a model explaining such a process for Jespersen's cycle. The function of emphasis in Ahern and Clark (2017: 8ff.) is that emphasis sharpens a standard of evidence, and that using an emphatic element signals that the speaker has better evidence than normal for the assertion. Carrying over this idea to our examples would mean that a speaker calling Rampage 'one stupid-ass movie' rather than 'a stupid-ass movie' indicates a higher degree of confidence and evidence with 32 Should this explanation be on the right track, it predicts that in a language with a fully functional dual, the cardinal 'two' should similarly have a hard upper bound. i i "unus-resubmitted-edited_GS" -2020/6/24 -8:05 -page 26 -#26 i i i i i i respect to the judgment. Similarly, for (41b), the idea is that a speaker asserting 'one cubit' signals higher precision and evidence than signaling simply the bare 'cubit'. 33 Whether the case at hand meets a high enough standard of evidence to warrant an explanation based on emphasis must be left for further investigation.

The increase of the emphatic form (in our case, the unity cardinal, as opposed to the non-emphatic bare form) can then be explained as an inflation process -which is a rather standard way of conceiving the dependence between meaning and frequency. 34 In a nutshell, the idea can be stated as follows: in having an emphatic and a non-emphatic form, there will be a partition of degrees of emphasis involved in an assertion: below some threshold x, the bare form will be used, whereas above this threshold, the unity cardinal will be used. Therefore, signaling emphasis provides for a rhetorical effect, which a hearer reacts to. 35 However, speakers are assumed to have a bias which drives the threshold down over time, such that the rhetorical effect is more and more diminished. 36 Eventually, this will lead to the disappearance of the non-emphatic, bare variant, and the optional unity cardinal will have become an obligatory indefinite article. 37

Phonetic erosion and scope issues

Finally, let us come to the problem of phonetic erosion. As I have pointed out, this is not a necessary process, but one can make a case that in languages like German or in Romance languages, the indefinite article is a clitic version of the cardinal. The old form can, however, still be used as a cardinal. How can this be accounted for?

Part of the answer to this question is related to some rather puzzling facts about scope dependencies. As we have seen, unity cardinals can appear without any problem within the scope of a quantifier. However, according to the standard classification of Heine (1997), narrow scope readings disappear in the development of the indefinite article. This seems somewhat paradoxical if one is not willing to assume that a form acquiring a new meaning will necessarily lose the old meaning. I will take the 33 There is actually evidence that this holds for English. Remember from footnote 28 that in COCA, the proportion of one inch as opposed to an inch is roughly 1:10. However, if we look at their combination with approximators, this proportion shifts considerably: an inch or so yields 155 hits in COCA, whereas one inch or so is a hapax. Therefore, there is reason to believe that in the minds of English speakers, a use of one inch is more precise a measure than a use of an inch.

34 Similar 'inflation models' of linguistic change, but less formalized and worked out, have been proposed by Dahl (2001) and Schaden (2012). 35 For details, see Ahern and Clark (2017: 12). 36 There are different ideas about what that bias may be; see Schaden (2012) and Ahern and Clark (2017) for relevant ideas. 37 One of the general weak points of such inflation-based accounts is that one would expect the force causing inflation to be active across all languages, whereas all languages do not develop an indefinite article (or else remain stationary at some point of the development). This remark is not only valid for the present sketch of the development of the indefinite article; it also applies to the better worked-out examples of inflation such as the present perfects and negation. position here that what is at stake is not the specific vs nonspecific readings, but actually the issue of the unity cardinal occurring under the scope of another scope-bearing element (be that a modal, or an adnominal universal quantifier). Note that the narrow scope indefinite configuration (henceforth •∃) is an unmarked configuration with respect to the wide-scope configuration (henceforth ∃•), in the sense that the latter is strictly more informative than, and constitutes a special case of, the former. 38 Consider ( 44):

(44)

Every citizen worships a god. a. Narrow scope: For every citizen x: there exists a god y such that x worships y b. Wide scope: There exists a god y such that, for every citizen x, it is true that x worships y.

Whenever (44b) is true, then (44a) will also be true; however, if (44a) is true, it might still be the case that (44b) is false (say, if I worship Isis, and you worship Mithras). Therefore, (44b) asymmetrically entails (44a), and we have a Horn-scale between these two meanings, where •∃ is the weak term (unmarked), and ∃• the strong (marked) term. It has often been observed that marked forms tend to associate with marked meanings, and that unmarked forms associate with unmarked meanings (a phenomenon known as the DIVISION OF PRAGMATIC LABOR, see, e.g., Horn 1989: 197f.). Therefore, associating a marked form (that is, unus N) to the marked meaning ∃• and the unmarked form (that is, the bare noun) with the unmarked meaning •∃ would be the expected outcome, and form a so-called Horn-strategy, whereas associating the unmarked bare form with the marked meaning (and vice versa) would correspond to an Anti-Horn strategy (see, e.g., van Rooy 2004). Let us see how we can derive this in the framework we have been using so far.

Notice first that using a definite article in order to signal wide scope would not only correspond to ∃•, but require the entity having wide scope to be presuppositional. Another, comparatively, would require that all elements in the discourse be different (see Grønn and Saebø 2012: 90). Therefore, both of these forms can be excluded as candidates in potentially marking scope ambiguities. So, in case of a narrowscope configuration, the most unmarked remaining form should be used, which is the bare form. On the other hand, in the case of a non discourse-linked wide-scope configuration, if this is deemed to be important enough to be marked, we should then reach for some marked form with a sufficiently compatible meaning. Once again, the unity cardinal is a plausible candidate for this use.

This prediction has, however, a loophole, allowing for a narrow-scope interpretation of the unity cardinal in one context. There is a second configuration which is asymmetrically entailed by •∃, namely if there is some importance to the fact that 38 As pointed out by Igor Yanovich (p.c.), this argument requires • to not be a negation (since ∃x¬P(x) ⊭ ¬∃xP(x)); as far as I can see, • can be any strong quantifier or modal operator. (45) For each citizen x, there is exactly one god y such that x worships y.

Once again, whenever ( 45) is true, then (44a) will also be true, but (44a) being true does not require (45) to be true (say, if you worship Mithras alone, but I worship Isis and Serapis). Therefore, there is a second Horn-strategy available.

If the use of Horn-strategies to explain scope dependencies is on the right track, this gives us the following empirical prediction: in the beginning stages of grammaticalization, if a unity cardinal is used, the speaker should target a marked interpretation. That is, we should not observe narrow-scope readings of a unity-cardinal, unless we have a restrictive meaning, in the sense of only one N. Should such narrow-scope readings be present, this would falsify the Horn-strategy explanation.

Notice, however, that there is a well-known descriptive generalization in the grammaticalization framework that lends support to the Horn-strategy hypothesis. We have the impression that, at some stage in its diachronic development (that is, stages 2-3 in Heine's scale), an indefinite article loses the possibility of taking narrow scope. Marking wide scope by means of a unity cardinal is just one way of giving a marked form a marked reading. However, the cardinality component of a unity cardinal is not causally related to the wide-scope reading (although it does nothing to impede it). Yet, in case of a narrow-scope reading insisting on the cardinality one, the semantic difference between the bare form and the unity cardinal is stressed. This would also mean that one should expect the determiner in the narrow scope context to always be accented, and therefore be perceived as the numeral (and it should not be able to undergo phonetic erosion in this context). Since the wide-scope marking does not intrinsically depend on any meaning component of the cardinal, one would not expect it to be systematically accented, and therefore it should be more susceptible to phonetic erosion in this use. In the long run, this could then lead to a dissociation between a cardinal (which is always accented) and an indefinite article (which is not).

Let me sum up the core idea defended in this section: there are very few contexts which would semantically require or prohibit a unity cardinal (as opposed to a bare singular, or an indefinite article), so its use comes down to whether the speaker is motivated to use a more marked form where it is possible but not strictly necessary. The motivation for use of the unity cardinal has been tentatively identified as emphasis, of which Ahern and Clark (2017) have provided a formalization. I have also introduced an explanation of how use can erode this emphasis. I have tried to demonstrate how the avoidance of indefinite articles in narrow-scope contexts can come about, and how this can also give us a clue about the diachronic process of the separation of a single form into two different forms (unity cardinal vs. indefinite article). While these ideas are still speculative, they provide a starting point from which a fully formal pragmatic and usage-based account of the extension of the use of unity cardinals can be explored, and where fully formal diachronic models of language change can be applied.

CONCLUSIONS AND PERSPECTIVES

In the present article, I have tried to complement the existing literature on the grammaticalization of indefinite articles by describing the discourse behaviour of unity cardinals in English and Latin. I have argued that this is a necessary endeavour because -while we have a good idea of the semantics of the indefinite article in languages like English (which is close to the diachronic endpoint of the grammaticalization process), and we also have a general understanding of the vector of change -the discourse behaviour of unity cardinals has so far not been investigated in sufficient detail. Therefore, we lack a solid baseline from which we can judge further developments. I have provided a formal account of the distribution of these cardinals based on the work by Grønn and Saebø (2012) and Amsili and Beyssade (2016). Empirically, I have tried to show that 'innovative' uses of unus in the Vulgate correspond quite closely to standard uses of unity cardinals, which I have taken to be exemplified by English one. Therefore, I have concluded that -for the Latin of the Vulgate -there is no need to assume that any kind of grammaticalization process has taken place. I have also tried to sketch by which pragmatic procedures the early stages of grammaticalization can be explained. Contrary to most preceding analyses, but in line with Pozas Loyo (2010), this account makes little use of semantic changes in a strict sense, at least for the initial stages of grammaticalization, but stresses factors such as the ability to be accented as important for the diachronic development of unity cardinals. Therefore, it is more in line with inflation-based approaches to language change like Schaden (2012) and Ahern and Clark (2017), and may open the analysis of the diachronic development of indefinite articles in this direction.

A NOTE ON METHODOLOGY: THE VULGATE AS A SACRED, AND TRANSLATED TEXT

This article has examined the use of unus in the Vulgate in its own right, and as a genuine (late) Latin phenomenon. Yet, to what degree does the use of unus in the Vulgate represent an actual Latin usage, or does it rather reflect a phenomenon of the source languages (or texts)? This is an extremely difficult question to answer in a general way (see, e.g., Calboli 2009 and Rubio 2009 for the more general question of the influence of Greek and Semitic languages on Latin), but the existing literature provides some answers.

A first potential worry stems from the fact that the Vulgate is a translated work. Since it is additionally an example of a holy (and divinely-inspired) text, a translator might be tempted even more to calque features from the source text that do not correspond closely to the target language's grammar. However, unlike other translations (e.g., into Syriac, where lost Greek originals can be reconstructed from the Syriac version), Latin translations are no word-by-word renderings of their Greek source text (see Houghton 2016: 143ff. on this issue).

A second problem concerns the source language of the translation. While for the New Testament, it is necessarily Greek, it is not that clear that the unique source for the Old Testament is Hebrew (and, to a lesser degree, Aramaic): Jerome's fluency in Hebrew has often been questioned (see Newman 2016), and it is certainly the case that he was familiar with the (Greek) Septuagint version of the Old Testament before he knew the Hebrew original. And even with respect to the New Testament, Jerome did not start from scratch: there were several preexisting Latin translations, collectively known as the Vetus Latina (for a description of the different manuscripts and their textual relations, see, e.g., Burton 2013, Houghton 2016).

Finally, there is also variation in the Greek source texts themselves, which have been classified into several "text types" (see Metzger and Ehrman 2005: 276ff.), even though the well-foundedness of these types has been called into question recently (see, e.g., Burton 2013, Houghton 2016)). The important point here is that Greek sources also vary with respect to the use of heîs (which is the Greek unity cardinal one). The edition of the Greek New Testament in PROIEL (see Haug and Jøndal 2008) is based on recent critical editions of the Bible (see Aland et al. 2012), whereas the Greek Orthodox Church liturgy uses a different recension (manuscripts in this tradition form the "Byzantine text type"), which is also the base of Erasmus's Textus Receptus (see Metzger and Ehrman 2005: 276-280). The Greek Orthodox majority text shows a heîs in a few passages, where other recensions lack it. 39 As an illustration, consider the following versions of the beginning of John 6:9, where (46a) is transliterated from Aland et al. (2012), whereas (46b) is transliterated from Hodges and Farstad (1985: 308), and where (46c) is from the Vulgate: Here, the Vulgate corresponds exactly to the Byzantine type, and not to the older manuscripts modern that critical editions are based on. While I duly acknowledge that these are potential problems, I do not think that these are critical. First, while being very different in some aspects, Latin, Ancient Greek and Biblical Hebrew are rather similar in their linguistic systems with regards to the expression of nominal indefiniteness: there is no indefinite article (the standard version is a bare singular), and they have a unity cardinal. Now, the question is: how different should we assume the cross-linguistic behaviour of unity cardinals to be in the first place, given that the main alternative is identical in the three languages? I venture that, as a working hypothesis, we should assume the meaning of one to be the same across languages, and its use should be governed by its meaning, and impacted by the distribution of its alternatives. Given these assumptions, we would not expect there to be any major differences.

Second, concerning the final source of the Vulgate, the presence or absence of unus might itself be taken as an indication of a possible textual source, and by comparing different textual traditions with respect to unus or heîs, we might end up retracing the history of the Bible (Hebrew and Greek for the Old Testament, and different Greek versions for the New). While certainly interesting, this is a task completely beyond what is doable in an article like the present one. It is, however, worth noting that in the rare instances where the Vetus Latina shows an influence from the Greek definite determiner (which is Finally, notice that Calboli (2009: 177f.) writes in his conclusions on the borrowings from Greek into Latin (an article of 130 pages, where unus is not mentioned even once): Despite many borrowings from Greek into Latin, some from Latin into Greek, and interference between the two languages, this interaction did not alter the core of the Latin language and grammar, because it never touched the core difference between the two languages. The core difference was the absence of the [definite] article in Latin and its presence in Greek with all the associated phenomena.

So, if the much more prevalent and grammatical definite article of Greek did not have an impact on Latin, we should probably not expect an impact of the Greek unity cardinal on Latin. Similarly, the only mention of the distribution of unus as influenced by Hebrew in Rubio (2009: 209) concerns the construction unus et unus ('one by one') as one instance of the use of reduplication in order to mark distributivity. 40 Summing up, we can thus state the following: i) the Vulgate (like other Latin translations of the Bible) does not slavishly copy its source word-for-word; ii) the Vulgate eliminated calques from the Greek determiner system present in preceding Latin translations; iii) the existing scholarly literature does not mention instances of unidiomatic or otherwise noteworthy Latin calques of Greek or Hebrew unity cardinals in the Vulgate 41 (even though there have been claims of unity cardinals having the meaning/use of indefinite articles); iv) it is not clear that we should expect variation in the behaviour of unity cardinals between Latin, Ancient Greek and Biblical Hebrew in the first place.

However, the existence of several textual traditions with respect to the use of unity cardinals (in Greek and Latin) clearly raises the issue of variation: why did some authors/scribes add (or fail to copy) a unity cardinal in some contexts? The basic fact here is arguably that there were contexts that allowed, but did not require, the unity cardinal -and this was probably the case in both Ancient Greek and Latin, and it continues to be true for contemporary English.

  ) member and unus N that is much greater than what is possible today in English. In rare circumstances, the uses of unus do not pattern necessarily with what one would expect from a unity cardinal, but they can be interpreted in ways consistent with what we have seen in English. Let me stress again that none of the referents introduced by unus is a particularly important character; most of them are (close to) throw-away references. Under the assumption that the five-stage model byHeine (1997) is correct, and that at the beginning of the process of grammaticalization stands the use of the (proto-)indefinite article with very salient characters in narration, unus cannot have become more article-like at this stage in time.

The distribution of indefinite articles is highly complex, and I cannot begin to do justice to the literature. For extensive discussion, see[START_REF] Hawkins | On (in)definite articles: Implicatures and (un)grammaticality prediction[END_REF].

(23) is directly fromGrønn and Saebø (2012: 82); the representation in (24) is taken from Amsili andBeyssade (2016: 13), who propose to amend the definition by[START_REF] Grønn | A, The, Another: A game of same and different[END_REF] (given in (i) below) by explicitly incorporating a unicity presupposition.

This explanatory strategy needs to be further worked out, and might ideally integrate the distinction between accent and stress (see, e.g., Büring 2016: chapters 6-7). However, it seems to me that -whatever the correct explanation turns out to be -it cannot be based on the semantic content of the items involved, because I do not see how one could exclude the indefinite article on such grounds. The partitive context can be formalized as follows:
