Alors between discourse and grammar: the role of syntactic position*

This paper presents an in-depth study of the semantics of the French discourse marker alors 'at that time, then, so'. Its evolution from temporal adverbial with local anaphoric meaning to polysemous marker including conversation management uses in spoken French is traced through a systematic diachronic corpus analysis. Of particular interest in this perspective is the relationship between the different meanings of alors and the position it occupies in the sentence. Our main hypothesis is that the semantic evolution of alors goes hand in hand with grammatical and functional changes leading to new discourse functions, viz. from sentence adverbial to discourse structuring marker. We show that semantic meaning is driven by syntactic position changes which gradually evolve over time.

Introduction

French alors 'at that time, then, so' has recently been the topic of quite some research [START_REF] Franckel | Etude de quelques marqueurs aspectuels du français[END_REF][START_REF] Gerecht | Alors: opérateur temporel, connecteur argumentatif et marqueur de discours[END_REF]Hansen 1197;[START_REF] Hybertie | La conséquence en français[END_REF][START_REF] Jayez | Alors: description et paramètres[END_REF][START_REF] Draoulec | Alors as a possible temporal connective in discourse[END_REF]. These authors give a good account of the uses of alors in Present Day French (PDF), but there still is no thorough diachronic analysis. One of the key issues that have been left undiscussed so far concerns the evolution of alors from temporal adverbial with local anaphoric meaning to polysemous marker including conversation management uses in spoken French. A systematic diachronic corpus study should help us reveal how and when the different uses of alors arose. Of particular interest in this perspective is the relationship between the different meanings of alors and the position it occupies in the sentence. Indeed, our main hypothesis is that the semantic evolution of alors goes hand in hand with grammatical and functional changes leading to new discourse functions, i.e. from sentence adverbial to discourse-structuring marker. In our view, alors is thus illustrative of the way sentence grammar and discourse grammar interact: changes at the sentence level lead to changes at the discourse level. This idea is of course not new. It links up with the idea dear to functional linguists that there is a determining relationship between the form and the function of a linguistic element. Lambrecht (1988:138), for instance, states that "there is a relationship between the form of a sentence and its function in discourse". Evers-Vermeul (2005:chap.3) reviews a number of studies that posit an interaction between the positioning and the function of connectives and adverbials, her general claim being that the speaker, when using "a multifunctional word 'exploits' its syntactic possibilities in order to differentiate between its functions" (2005:32). In line with these studies, our analysis aims to unravel how alors has come to "exploit" its syntactic possibilities in a diversity of meanings.

Two specific research questions will help us reach our goal:

• What is the evolution of the semantic distribution of alors from Old French (OF) to Present Day French (PDF)?

• To what extent is there a relationship between the semantic and functional evolution of alors and its position in the sentence?

The paper is structured as follows. Section 2 reviews the literature on the semantics of alors and distinguishes three main uses: temporal, causal, and metadiscursive. Section 3 outlines how the position and meaning of alors have been handled in these studies.

Section 4 describes the data used in the present study. Section 5 gives the results of our diachronic corpus analysis from Old to Classical French, and from Classical French to PDF, both written and spoken. Section 6 couples this semantic evolution to the evolution of the position of alors in the sentence. Section 7 contains a number of conclusions and perspectives for future research.

Semantic distribution of alors

Alors in PDF shows a wide variety of semantic uses. Among these, three primary meanings can be distinguished: temporal, causal, and discourse-structuring [START_REF] Franckel | Etude de quelques marqueurs aspectuels du français[END_REF][START_REF] Gerecht | Alors: opérateur temporel, connecteur argumentatif et marqueur de discours[END_REF]Hansen 1197;[START_REF] Hybertie | La conséquence en français[END_REF][START_REF] Jayez | Alors: description et paramètres[END_REF][START_REF] Draoulec | Alors as a possible temporal connective in discourse[END_REF]. Two main constraints seem to hold throughout all uses of alors (Franckel 1989:134): there is a semantic relationship between the connected elements which amounts to more than a relationship of simple succession, and the connected elements must be genuinely different from one another. We will come back to these constraints in the description of the different uses of alors.

Temporal alors

From a historical point of view, the primary meaning of alors is temporal, as in example (1) below. It is a compound of the preposition and prefix à 'at' and lors 'then', which in turn originates in Latin ILLA HORA, an ablative 1 meaning at that hour. Its original meaning -and the only one attested in Old French, at least in our corpus, cf. Section 4is that of temporal simultaneity, sometimes, but not invariably, with a sense of duration, (cf. [START_REF] Hansen | Alors and donc in spoken French: A reanalysis[END_REF]. Alors retains a temporal meaning in PDF, as in examples (2)(3) below. This use has been described in detail by [START_REF] Gerecht | Alors: opérateur temporel, connecteur argumentatif et marqueur de discours[END_REF] and [START_REF] Hybertie | La conséquence en français[END_REF].

Both authors have inspired a number of follow-up studies (Le [START_REF] Draoulec | Alors as a possible temporal connective in discourse[END_REF]Paillet-Gruth 1996). 'But the night fell and the rain still hadn't stopped. Alors, the countess got careless: without telling anyone anything, when everyone went up to bed she put on her boots under her nightgown …'

According to Gerecht (1987:71), in the construction p alors q, temporal alors establishes the reference time of p as the temporal landmark (repère temporel) of q.

Accordingly, relationship between t1 and t2 can be one of plain or partial temporal concomitance, succession, or anteriority. The propositional content of p and q alone determines which of these temporal meanings is expressed. According to Hybertie (1998:23-44), temporal concomitance between p and q can be glossed by à cette époque-là, à ce moment-là 'at that time' and is triggered by an explicit temporal reference in p, such as en 1968 in example (4):

(4) J'ai commencé mes études de Lettres en 1968. Il n'y avait alors qu'une seule faculté de Lettres et Sciences humaines à Paris. (Hybertie 1998:24) 'I started studying Arts in 1968. There was alors only one Faculty of Arts and Human Sciences in Paris.'

However, as we will show, the concomitant reading does not always require the presence of an explicit temporal reference. Following [START_REF] Jayez | Alors: description et paramètres[END_REF] and [START_REF] Franckel | Etude de quelques marqueurs aspectuels du français[END_REF],

Hybertie distinguishes a second temporal use of alors that has no explicit temporal landmark in p. 2 In those cases, there is no strict concomitance between the states of affairs described in p and q, but rather temporal succession: "alors builds a sequence of temporally ordered events … a temporally ordered succession that is linked to a logical order of events taking place, the first event being presented as the condition for the realization of the second [our translation]" 3 (Hybertie 1998:25). Such a context can be found in example ( 5), where alors forces a reading in which my seeing him arrive is conditioned by my arrival at the village square:

(5) Je suis allé jusqu'à la place du village, je l'ai alors vu arriver. (Hybertie 1998:24) 'I walked up to the village square, I alors saw him arrive.'

This dependency between p and q corresponds to Franckel's (1989) "disjunctive resumption" (reprise disjunctive) according to which alors requires two distinct states of affairs, which are validated, or more precisely acknowledged and accepted by the hearer (hereafter simply validated), successively after setting p's temporal reference to q, p and q being ordered according to the natural order of things ("selon l'ordre des choses"; Hybertie 1987:28). Thus, for a temporal succession reading of alors, a temporally logic dependency relation is required.

Summing up Hybertie's view, either temporal alors cues an explicit concomitant reference time in q, or it establishes a successive temporal relationship between p and q, where q is conditioned by p, and where p does not contain an explicit temporal landmark.

Interesting as it might seem, we will not follow Hybertie's distinction according to which it is the presence or absence of an explicit temporal landmark that determines the temporal value of alors. Rather, in line with Le Draoulec & Bras (2007:85), we believe that the temporal value of concomitance is not due to the presence of a temporal adverbial en 1968 in the above example, but to the imperfective aspect of q. This makes it possible to account for (6), an example that resists straightforward explanation by Nevertheless, aspect alone cannot account for temporal concomitance. On the contrary, we believe that Franckel's notion of disjunctive resumption also holds for these cases.

Once p's state of affairs [our leaving the movie theatre] is validated, the temporal landmark of p [the moment we left the movie theatre] is picked up by q, which is then validated as being concomitant with p because of the imperfective aspect of pleuvoir. If p is not validated, its temporal landmark cannot be picked up by q and the relationship between p and q cannot be interpreted temporally, as illustrated in our constructed example (7):

(7) Il se pourrait qu'ils soient sortis du cinéma. ?#Il pleuvait alors sur Nantes.

'They might have left the cinema. It was raining alors on Nantes.'

For our corpus analyses, the following parameters were used for the identification of temporal alors:

• p and q are two independent states of affairs

• p contains an explicit or implicit reference time that serves as landmark to q

• q is posterior to or concomitant with p

• alors can be glossed by à ce moment-là 'at that time', ensuite 'then'

• if alors is deleted from the sentence, there is no argumentative relation causal, conditional, or other, between p and q.

Causal alors

According to the literature, alors can also be used to mark consequential or resultative relations with an argumentative rather than a strictly temporal meaning [START_REF] Forget | Quelques particularités des connecteurs de consécutivité: essai polyphonique[END_REF][START_REF] Franckel | Etude de quelques marqueurs aspectuels du français[END_REF][START_REF] Gerecht | Alors: opérateur temporel, connecteur argumentatif et marqueur de discours[END_REF][START_REF] Hybertie | La conséquence en français[END_REF][START_REF] Hansen | Alors and donc in spoken French: A reanalysis[END_REF][START_REF] Jayez | Alors: description et paramètres[END_REF]Zénone 1982).

According to Zénone (1982:136) these temporal and consequential meanings are closely linked, leading to a subjective conclusion granted by the speaker. This means that the information conveyed by q may not be presupposed or pre-asserted (Forget 1986:32).

Examples from our corpus illustrate this close relationship between temporal and causal meanings, with (8) having the conclusive gloss donc 'so' and (9) the more conditional gloss dans ce cas 'in that case'. In both cases, the cause-consequence relation expressed by alors is contingent, i.e. context-dependent (Hybertie 1996:30).

( 'Simply give them something to eat and they'll all be pro-German! Mother insisted: one had to be consistent. Non-Jewish? Alors Non-Jewish all the way.'

As to the conditional uses, the question arises whether they should be treated as a subcategory of the causal uses or as a separate category. Hansen (1997:181) notes that it "is not clear from the literature whether the extension from temporal to conditional uses of alors preceded, followed, or was perhaps simultaneous with the extension to resultative structures." Both options seem equally plausible. The extension to conditional contexts could be explained by the existence of certain fundamental patterns of inference: "when one state of affairs is seen as forming the background for another, the assumption will frequently be made that the former is also the cause of the latter" Hansen (1997:181; see also [START_REF] Vogl | Het belang van conditionaliteit voor de ontwikkeling van temporeel naar causaal voegwoord. De geschiedenis van dewijl, terwijl, weil en while[END_REF]. Hybertie (1998) 'Let on clearly that you are jealous, and get more angry yet whenever she speaks to a man; alors she will admit her mistake, and stop being so jealous.'

In our diachronic corpus analysis, we tried to disentangle this evolution from a temporal use to various subcategories of causal uses, see Section 5. The following parameters for causal alors were used:

• p and q are two independent states of affairs (SoA) or utterances

• alors can be paraphrased by par conséquent, du coup, donc 'consequently, therefore, so' and/or si bien que 'so that'

• the causal reading remains in the absence of alors

• the SoA described in q is not possible without the SoA described in p.

We distinguish two further uses close to causal alors: temporal uses in causal contexts, and conditional uses. In the first case,

• alors can be glossed by both temporal and causal markers (see above), but

• the causal reading does not remain in the absence of alors

For the conditional uses:

• p and q are two independent inferential states (Hybertie 1996:31) • alors can be glossed by dans ces conditions, dans ce cas 'in that case'

• in the absence of (si) alors the conditional meaning does not remain

• the SoA in q depends on the occurrence/existence of the SoA in p.

A special case of conditional use seems to be the construction ou alors 'or else'.

According to Hybertie, ou alors contains an underlying "si … alors" 'if … then', as in example 11:

11 Je te l'apporterai, ou alors [ou si je ne te l'apporte pas alors] je te l'enverrai par la poste. (constructed example)

'I will bring it to you, or else [or if I don't bring it] I will send it by mail.'

If the two propositions are related by ou 'or' only, both of them are presented as equally valid. In the case of ou alors, however, the choice between the two propositions is not equivalent anymore: first P1, and if not, then P2. This close relation between the ou alors-construction and the conditional si…alors construction has led us to count the former among the conditional uses of alors.

Metadiscursive alors

Several authors attribute a number of additional functions to alors which we will group here under the label of metadiscourse marker. According to Zénone (1982), alors is used as a conversation-structuring marker ('marqueur de structuration conversationnelle'), introducing new discourse units and hinting to the relevance of upcoming discourse. [START_REF] Hybertie | La conséquence en français[END_REF] speaks of alors as a structuring marker ('marqueur de structuration') in this context, which in her view is restricted to spoken language with the purpose of maintaining discourse coherence. Typically, this use of alors occurs when speakers are retelling a past experience linking together different pieces of discourse. A rather extreme example from our corpus of spontaneous conversation is given in ( 12):

(12) mais alors ce qui était marrant c'est que euh / tout à coup il s'arrêtait / et alors euh / assez vite alors xx se disait maintenant vous vous dirigez vers telle porte // mais alors (20 th c. -spoken)

but alors the funny thing was that er / suddenly he stopped / and alors er / quite quickly alors xx was saying now you go towards the door // but alors Hansen (1997:172) pursues the same idea when she states that alors "is not infrequently used to mark shifts to new topics, particularly subtopics or digressions." (13) is an illustrative example from our corpus where alors is used to introduce a subtopic about the kind of language used by the speaker's baby daughter. 'and then she stayed stuck on me (laughter) / and er / she grew up and then she starts a / she starts to talk a little // alors she says er / she says 'doudou' for all the things she likes / and she says 'maman' for all the persons she / likes' More generally, alors is used in these contexts to re-frame or re-perspectivize the discourse so that the addressee remains "able to construct a mental representation of the discourse with a minimum of effort" (Hansen 1997:180) notwithstanding perspective and frame shifts. Closely related to this function of shift marker is what [START_REF] Franckel | Etude de quelques marqueurs aspectuels du français[END_REF] describes as a turn-taking signal ('signal de prise de parole'), 4 although the latter is restricted to initial position, as in example ( 14) from our corpus: In our corpus analysis, the following parameters for metadiscursive alors were used:

• alors does not establish a temporal or argumentative relation

• alors can be left out without changing the semantic content

• alors can be glossed by other topic shifters, such as bon 'well', or transition markers, such as et puis 'and then'.

Position of alors in the sentence

Most studies of alors try to show that there is a relation between the position of initial, medial, final alors and its meaning, although this relation is neither univocal nor deterministic. Le [START_REF] Draoulec | Alors as a possible temporal connective in discourse[END_REF], for instance, try to establish a link between temporal alors, its position, and connective function. On the basis of Creissels ' (1995) observation that a range of adverbials in fact have a syntactic function that is close to coordinators because they establish a relationship between their host and another sentential structure, the authors hypothesize that initial alors necessarily expresses a dependency link between S1 and S2, while medial or final alors does not.

The specificity of initial alors is stated in various ways by different authors:

deductive and intrasubjective 5 for Franckel (1987), but mostly consecutive for Hybertie (1996:25). Le Draoulec & Bras put it more strongly: for them, "[o]nly initial alors, implying a dependency link between the utterances, licences the relation of temporal succession with a temporal gap between the events described" (2007:7). This is, according to them, a "strong constraint, which does not depend on semantic or pragmatic conditions" (2007:7), to the point that alors can be said to function, in this position, as a connective.

The fact that medial alors is mostly temporal is noted by Le Draoulec & Bras and by Hybertie; medial alors can also describe a relationship of cause to consequence according to Hybertie. In any case, it cannot be considered as a connective in this internal position. Hybertie states this strongly, Le Draoulec & Bras less so. In final position, alors is exclamative according to Hybertie and intersubjective (cf. Franckel's

Tu viens, alors?! "Are you coming, [alors]?", where alors denotes the urgency of the invitation). Hansen (1997:182) furthermore notes that whenever resultative alors is utterance-final it is "found with statements made on the basis of inference from prior discourse by the interlocutor, and which therefore usually function[s] pragmatically as requests for confirmation". This suggests to her that "utterance-final alors may be a candidate for grammaticalization as a modal particle". Her data are however not sufficient to draw any generalizations.

The relationship between sentence position and grammaticalization has been hypothesized specifically by [START_REF] Traugott | The role of the development of discourse markers in a theory of grammaticalization[END_REF] in her grammaticalization cline of discourse markers, according to which clause-internal adverbials move to sentence adverbials which can in turn develop to discourse particles. We would like to suggest that alors is a plausible candidate for analysis in terms of this cline. A close analysis of both position and meaning in our diachronic data should help us take a firmer position on this idea.

In our corpus analyses, the position of alors has been defined as follows:

• initial alors is located in the left periphery of the sentence/utterance, that is, outside the argument structure of the verb; occurrences of et alors, puis alors, mais alors, etc. are counted as initial;

• medial alors is internal to the argument structure, mostly after the finite verb and before the non-finite verb, if present;

• final alors is located in the right periphery, after the non-finite verb, if present.

Sentence/Utterance has been operationalized in clausal terms. S1 is the clausal segment (predicate-argument structure with adjuncts) preceding the alors-segment (S2). Mostly, in writing, the clause corresponds to an orthographic sentence, in speech to a turn construction unit [START_REF] Selting | The Construction of Units in Conversational Talk[END_REF].

Presentation of the data

We designed a specific corpus for this study, using texts from various databases. Our goal was to have comparable texts over a very large period of time, ranging from the appearance of alors in the 12 th c. to PDF, with a focus on two periods: the emergence of alors from the 12 th to 17 th c., and the contrast between spoken and written language in PDF at the end of the 20 th c.

We included texts from the following databases: BFM Database for Medieval French, Champion Electronique, 6 Frantext and VALIBEL Spoken French. In order to ensure comparability over different periods, we selected the novels and short stories present in each database except, of course, for the spoken data, and excluded technical texts, essays and so on.

For the first part of the corpus, i.e. the emergence of alors, we distinguished three periods, based on the relative frequency of alors, see Table 1 below, and studied all occurrences: 34 for the first period (12 th to 14 th c.), where its frequency is extremely low (0.2/10,000 words), 146 for the second period (15 th c.), where its relative frequency is five times higher (1.07/10,000 words), and 276 for the third period (16 th to 17 th c.),

where its relative frequency (3.62/10,000 words) is three times higher than in the second period.

For PDF we took both written and spoken data into account. The written data come from the Frantext database (http://www.frantext.fr), from which we extracted all alors items occurring in 20 th c. novels (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000). This resulted in a subcorpus of 3,245,366 words with 3348 occurrences of alors. Thus, our item appears to have a very high frequency of 10.32 occurrences per 10,000 words. We then made a random selection of 100 items for our parameter analysis.

The spoken data are extracted from the VALIBEL database 7 [START_REF] Francard | La banque de données VALIBEL : des ressources textuelles orales pour l'étude du français en Wallonie et à Bruxelles[END_REF][START_REF] Dister | Du corpus à la banque de données. Du son, des textes et des métadonnées. L'évolution de banque de données textuelles orales VALIBEL[END_REF]. We worked only with the subcomponent of spontaneous face-to-face conversations, which totals 3 hours and 48 minutes of speech with 50,668 words and 3373 turns, with 199 occurrences of alors. In terms of frequency, it turns out that alors is four times more frequent in spoken language than in writing, since it occurs 39.28 times per 10,000 words. Here again, we made a random selection of 100 items for our parameter analysis.

Table 1 summarizes the data used for our analysis 8 and demonstrates the tremendous rise in frequency of alors through the different periods under investigation.

In regard to this high frequency, it is interesting to keep in mind that [START_REF] Mair | Corpus linguistics and grammaticalisation theory. Statistics, frequencies, and beyond[END_REF] considers high frequency as going hand in hand with the grammaticalization of an item or construction (see also Bybee & Hopper 2001).

[insert Table 1 here]

Our selection thus includes over six hundred occurrences of alors, as shown in Table 2.

[insert Table 2 here]

Our parameter analysis includes the following variables:

• modality: written, spoken

• language period: Old French 12-14 th c., Middle French 15 th c., Classical

French 16 th -17 th c., Modern French late 20 th c.

• semantic meaning of alors: temporal, causal, conditional, metadiscursive

• position of alors: initial, medial, final 5 Evolution of alors

Diachronic evolution of alors from Old to Classical French

According to dictionaries (e.g. Trésor de la langue française), alors appears in 12 thcentury Old French as a prefixed variant of lors 'then', which appeared in Old French at the end of the 11 th century (Roland) with temporal uses. In our corpus, which is composed of literary texts ranging from the 11 th to the 17 th centuries, alors indeed appears in the 12 th century. Its frequency, nevertheless, is very low until the 15 th , as was shown in Table 1 above.

Temporal uses: alors 1

At first view, the semantic evolution of alors from Old to Classical French appears to be fairly limited. In any case, it contrasts greatly with the polysemy of alors in PDF, which we described above. In Old French, as [START_REF] Hansen | Alors and donc in spoken French: A reanalysis[END_REF] and [START_REF] Hybertie | La conséquence en français[END_REF] This use of alors will be referred to as alors 1 .

Temporal uses in causal context: alors 2

However, at the end of the 13 th century alors already appears in a new type of context.

According to Hybertie, it then expresses a logical relationship of cause to consequence.

We would prefer to state that alors retains a temporal meaning, but appears in contexts in which it can take on a causal meaning. Example ( 16) below illustrates our point:

(16) "Si m'aït Diex! ce dist li rois, dans chevaliers, si feroie ausi hardiement com vous feriés." Et Dynadans se conmenche alors a seignier, ausi com s'il tenist cheste cose a grant merveille (Roman de Tristan en prose, 13 th century, 1 st ed. 1963, t. IV/III/22, p. 89)

'"God help me!" said the king, "lord knight, I would do as bravely as you". And Dynadans started alors to make the sign of the cross, as if he took this to be a great marvel.' As illustrated in this example, in Medieval French the interpretation of alors as a marker of causal relationship is generally subordinated to a temporal interpretation: in ( 16),

Dynadans necessarily makes the sign of the cross right after the king's utterance. Alors is thus still temporal, even if it already takes on a causal meaning. This use of alors will be referred to as alors 2 .

Even in example ( 17), in which the temporal relationship seems secondary, the temporal interpretation is not excluded: the king of arms (je in this excerpt) repeats what he said earlier because of the other king's order; but this necessarily happens right after that order. Thus, the temporal meaning of alors is not yet absent.

( At any rate, an important point is that this use of alors increases with time: it is quite marginal in OF but less so in Middle French (MF), with less than 5% in OF, but close to 30 % in MF (see Figure 1 below).

Temporal uses in hypothetical context: alors 3

A second step in the evolution of alors is that, from the 14 th century on, alors appears in conditional/hypothetical contexts, with constructions such as "if X does this, alors…".

In this type of context, alors can be glossed as "in that case", even though it can still be interpreted as a temporal marker. However, in example ( 18), the use of or 'now' in the same sentence, just after alors, seems to exclude a temporal interpretation, because the temporal meanings of alors 'then' and or 'now' are mutually exclusive:

( This use of alors, which we call alors 3 , appears more sporadically than the temporal use in causal context alors 2 .

Semantic evolution of alors

Our data show that the semantic evolution of alors is fairly rapid, even though its polysemy is limited. Figure 1 below illustrates this point:

[insert Figure 1 here] Causal contexts appear as soon as the 13 th century, and conditional contexts in the 14 th .

From the 15 th century on, the proportion of purely temporal uses drops to approximately 65 % of the cases and remains stable until the 17 th century. It seems that we can exclude, at least for alors, the idea that causal uses appeared after or grew out of conditional uses, contra [START_REF] Vogl | Het belang van conditionaliteit voor de ontwikkeling van temporeel naar causaal voegwoord. De geschiedenis van dewijl, terwijl, weil en while[END_REF].

From Classical to Present Day French: the rise of polysemy

Present Day French alors presents a rich semantic distribution that is strikingly different from Classical French and earlier periods. While temporal uses remain frequent in writing, with 35 % of the occurrences, metadiscursive (26 %), causal (22 %; including temporal uses in a causal context) and conditional (17 %) uses have taken an important place in the overall picture. Figure 2 illustrates the evolution from Classical to Modern French writing.

[insert Figure 2 here]

The semantic evolution of alors from Classical French to PDF shows statistically significant divergences (X²(3) = 90.52; p < .0001; Cramer's V: 0.491). 9 This shows up especially in the drop in temporal uses (Z = -2.9), and the rise of conditional uses (Z = +2.17) and even more of metadiscursive uses (Z = +7.26). 10 In the light of these results, we can only agree with Hansen's (1997:164) observation "that the general evolution of the two markers [alors and donc], away from the temporal sense, in which they contribute to truth-conditional meaning, and towards a metadiscursive function, provides support for Traugott's (1982:256) hypothesis that '[i]f there occurs a meaningshift which, in the process of grammaticalization, entails shifts from one functionalsemantic component to another, then such a shift is more likely to be from propositional through textual to expressive than in reverse direction.'" A comparison of written and spoken data in PDF confirms and strengthens this evolution from temporal to metadiscursive, and is illustrated in Figure 3.

[insert Figure 3 here] The variation between written and spoken PDF is highly significant (X²(3) = 45.03, p < 0.0001; Cramer's V: 0.475): writing clearly favors temporal use (Z = +3.84) while speech favors metadiscursive use (Z = +2.77). Note furthermore that the written data include direct speech, which is supposed to mirror natural spoken behavior. If we exclude all cases of quoted speech from the written data, the contrast in the alors distribution becomes even stronger (X²(3) = 86.578, p < 0.0001; Cramer's V: 0.760).

The determining factors for this contrast stay the same: temporal use in narrative writing (Z = +5.8) vs. metadiscursive use in spontaneous conversation (Z = +3.1). It is interesting to note that such variation in speech and writing also occurs in other French connectives (see e.g., [START_REF] Simon | Connecteurs de causalité, implication du locuteur et profils prosodiques: le cas de car et de parce que[END_REF] on car and parce que 'because'). It remains to be investigated whether this variation is indicative of an ongoing grammaticalization (Degand & Fagard 2008;Fagard & Degand 2008). Let us now address the issue of syntactic position. Is it the case that semantic evolution and syntactic variation go hand in hand?

The evolution of alors and syntactic position

The syntactic position of alors in the sentence undergoes a stepwise evolution from Old

French to spoken PDF. In Old French, alors is found mainly in medial position, but from Middle French on right up to both spoken and written PDF, a majority of cases is found in initial position, with a slow rise of alors occurrences in final position from Classical French onwards (X²(8)=81.457; p < .0001; Cramer's V: .249). A closer analysis of the data reveals that the significant divergences in syntactic position are caused by the higher proportion of medial alors in Old French (Z = +5.2), on the one hand, and by the lower proportion of medial position in PDF speech (Z = -3.9), on the other. In other words, alors jumps from medial position in Old French to initial position from Middle French onwards, and ends up nearly exclusively in the periphery of the sentence in PDF speech.

[insert Figure 4 here] So far, this evolution seems to confirm [START_REF] Traugott | The role of the development of discourse markers in a theory of grammaticalization[END_REF] hypothesis that discourse particles find their origin in clause-internal adverbials that develop into sentence adverbials before they eventually reach the stage of being a discourse particle characterized by syntactic freedom and increased scope. So, the question at stake now is whether the evolution in the syntactic position of alors goes hand in hand with the semantic evolution described in Section 5. We will postulate here that clause-internal Let us first have a look at the relationship between semantic function and syntactic position in PDF. From this synchronic picture, we will then move backwards in time to try to trace the evolution of this supposed relationship.

Syntactic position and meaning of alors in Present Day French

Syntactic position and meaning of alors in PDF writing

Figure 5 gives an overview of the semantic distribution of alors as a function of its position in the clause/sentence in PDF writing.

[insert Figure 5 here] Most strikingly, it appears that medial position is used exclusively for temporal alors, while initial position is where we find most occurrences of all types (59% of the data), and final position is only poorly used (12%). Statistically, this distribution is significantly divergent 11 (X²(4) = .0001, Cramer's V: .499), and is of course due to the overrepresentation of temporal uses in medial position (Z = +4), and the overrepresentation and underrepresentation respectively of cause-conditional (Z = +2.4) and temporal uses (Z = -2.4) in final position. These first results come close to our hypotheses regarding the relationship between the meaning of alors and its syntactic position: we find connective-like causal, conditional and temporal meanings in initial position as well as metadiscursive uses; temporal uses in medial position, and a restricted number of other uses in final position, namely causal, conditional, and metadiscursive. These results do however need some fine-tuning. We would for instance like to know what kind of temporal uses are found in initial vs. medial position.

To this end, we need to have a look at temporal uses only. We distinguished temporal succession from temporal concomitance in Section 2.1. Recall that we expect concomitant alors ('at that time') to occur primarily in medial position, functioning as a clause-internal adverbial, while alors expressing temporal succession ('then, thereafter') should function primarily as a connective in initial position. This hypothesis appears to be borne out, at least partially. Figure 6 shows that concomitant alors indeed hardly ever occurs in initial position, while successive alors occurs both in initial and medial position (X²(1) = 5.776; p < .05, Cramer's V: .351).

[insert Figure 6 here]

The metadiscursive uses also show a clear divide between their function and their syntactic position. All 16 instances of topic shift markers are found in initial position, while interjection uses (et alors?; ça alors?) are almost equally divided over initial (3 instances) and final position (4 instances). These observations are too low to draw any statistical conclusions, but they speak for themselves. The metadiscursive uses in these written data call for an additional observation: all 23 occurrences are found in quoted speech, which leads to the conclusion that metadiscursive alors is typical of spoken language.

Syntactic position and meaning of alors in PDF speech

In view of the divergent semantic distribution of alors in the spoken and written data (cf. Section 5.2), we expect a different overall picture with respect to the relationship between the semantics and the position of alors. As already mentioned, [START_REF] Hansen | Alors and donc in spoken French: A reanalysis[END_REF] considers that such utterance-final intersubjective uses belong to the epistemic level in [START_REF] Sweetser | From Etymology to Pragmatics: Metaphorical and Cultural Aspects of Semantic Structure[END_REF] terms, fulfilling a pragmatic function. This intersubjective use, together with its quasi-systematic occurrence in interrogative clauses and peripheral position in the clause, leads us to follow her suggestion that these occurrences of alors could be involved in a grammaticalization process into modal particles, which could in turn function as turn-transition devices [START_REF] Selting | The Construction of Units in Conversational Talk[END_REF]. However, we do not have enough data to investigate this issue further, and will leave it for future research.

[insert Figure 7 here] The final step in this investigation consists in relating the evolution of syntactic positioning (cf. Section 6, Figure 4) to the evolution of the semantics of alors (Section 5.1.4, Figure 1).

Evolution of syntactic position and meaning of alors

We have seen that together with a steady rise in frequency, alors presents a stepwise evolution from mainly medial position to initial position and eventually to peripheral position (initial and final). Thus, in Old French, alors presents 29 % (10) of its occurrences in initial position, 62 % (21) in medial position, and 9 % (3) in final position. In Middle French, alors presents 85 % (124) of its occurrences in initial position, 14 % (20) in medial position, and 1 % (2) in final position. And, in Classical

French, alors presents 70 % (191) of its occurrences in initial position, 24 % (66) in medial position, and 7 % (19) in final position. Finally, as mentioned before, PDF writing presents 59 % of occurrences in initial position, 29 % in medial position, and 12 % in final position. 12 At the same time, the meaning of alors evolves from purely temporal uses to temporal uses with causal and conditional connotations -since the latter present low frequencies we have grouped them together into one category -and eventually to metadiscursive uses. The evolution can be described as follows: In Old French, 88%

(30) of the alors occurrences are purely temporal, and 12% (4) are temporal in a causal or conditional context. In Middle French, 66% (96) are temporal and 34% (50) have an added causal or conditional meaning. In Classical French, this proportion stays the same: 65% (179) are temporal, and 35% (97) are used in a causal or conditional context.

Finally, in PDF writing, 35% are temporal, 49% are causal or conditional, and 26% are metadiscursive in use. An approximate representation of this evolution is given in To put this hypothesis to the test we performed a loglinear analysis 13 with the factors period, meaning, and position. A few words of caution are in place on how we performed the analysis. For lack of data for certain variables and in order to ensure comparability of the different time periods, we collapsed a number of variables in the following way: the category 'position' covers two variables: peripheral (initial + final) and clause-internal (medial); the category 'meaning' also comprises two variables:

purely temporal (temporal) and other meanings (causal, conditional, metadiscursive).

The three-way interaction thus concerns Period (Old French, Middle French, Classical French, PDF) x Meaning (purely temporal, other) x Position (peripheral, clauseinternal).

The three-way loglinear analysis produced a final model that retained all effects.

The likelihood ratio of this model was X²(0) = 0, P=1. This indicates that the highestorder interaction, i.e. the period x position x meaning interaction, was highly significant (X²(3) = 35.135, p < .0001). In other words, the interaction between position and meaning differs per period. To break down this effect, separate chi-square tests were performed on the period and meaning variable for each position; the period and position variable for each meaning; and the position and meaning variable for each period. This leads to the following results. There was a significant association between the meaning expressed by alors and the period of time, both in peripheral position (X²(3) = 34.625; p < .0001; Cramer's V: .287) and in clause-internal position X²(3) = 12.673; p < .005;

Cramer's V: .305). This effect is explained in the first place by the low frequency of other meanings for alors in peripheral position in Old French (Z = -2.0) vs. a high frequency in PDF (Z = +3.7); and the high frequency of other meanings in Classical

French in clause-internal position (Z = +2.1) vs. a low frequency in PDF (Z = -2.0).

There was also a highly significant association between the position of alors in the sentence and time period, both for temporal alors (X²(3) = 34.033; p < .0001; Cramer's V: .310) and other types of meanings expressed by alors (X²(3) = 36.798; p < .0001;

Cramer's V: .426). This accounts for the fact that temporal alors occurs mainly in clause-internal position in Old French (Z = +2.5) and PDF writing (Z = +3.2), while it occurs significantly less frequently in clause-internal position in Middle French (Z = -2.1) and in peripheral position in PDF writing (Z = -2.3). On the other hand, other meanings of alors appear more in clause internal position in Old French (Z = +4.4) and Classical French (Z = +2.2), and less so in Middle French (Z = -2.1) and PDF writing (Z = -2.1). Finally, there was no significant association between the meaning expressed by alors and the position of alors in the sentence in Old French. For all other periods, such a significant association did exist. In Middle French, the significant association (X²(1) = 12.07; p < .001; Cramer's V: .288) can be explained mainly by the fact that clauseinternal position does not favor non-temporal meanings (Z = -2.6), while peripheral position does. In Classical French, the association is significant but rather weak (X²(1) = 5.868; p < .05; Cramer's V: .146). The association is strongest in PDF writing (X²(1) = 44.249; p < .0001; Cramer's V: .665), which mainly favors temporal alors in clauseinternal position (Z = +4) and other meanings in peripheral position (Z = +2.5).

The analysis reveals a number of interesting outcomes, some more clear-cut than others. First of all, time period does favor peripheral position: the later the period, the more occurrences of alors are found in peripheral position or more exactly, the fewer alors occurrences are found in clause-internal position. This is not totally true of PDF writing, which sees an increase of alors occurrences in clause-internal position, but this seems to be linked to a specialization of the meaning of alors ('at that time') in this position (cf. Section 6.1.1). Furthermore, the analysis confirms that the meaning changes over time, with a steady increase of other meanings for alors at the expense of its purely temporal meaning. With respect to the question whether it is syntactic change that favors new other meanings, or whether new meanings call for syntactic innovation, the analysis seems to reveal that the appearance of new syntactic positions precedes the occurrence of new meanings. In Old French, few other meanings are found for alors in peripheral new position, and in Middle French and in Classical French this tendency for underuse persists although not significantly anymore, while PDF writing clearly demonstrates a massive use of other meanings in peripheral position together with an underrepresentation of purely temporal uses in this position. As for clause-internal position, the divide between temporal and other meanings for alors remains stable throughout Old and Middle French. This conforms to the grammaticalization parameter of "layering" [START_REF] Hopper | On some principles of grammaticalization[END_REF], i.e. the persistence of older forms or meanings alongside new ones. In PDF writing, the other non-temporal meanings seem to have chosen their side and do not occur anymore in clause-internal position. However, in between, in Classical French, clause-internal position sees a rise of other meanings for alors which we cannot readily explain.

In our view, the evolution of alors from clause-internal temporal adverbial to peripheral connective or discourse markers exemplifies Heine's (2002:86-87)

Conclusions

The aim of this study was to unravel the relationship between the evolution of the meaning of alors from Old French to Present Day French and the position it occupies in the clause/sentence. The underlying hypothesis was that this meaning evolution goes hand in hand with a move from a sentence-internal function to a discourse-structuring function.

Our diachronic corpus study adduced evidence for the progressive diversification of the meanings of alors, from purely temporal in Old French to broad polysemy in PDF. We also showed that alors does indeed evolve from an adverbial, A corollary question is whether this evolution should be interpreted in terms of a grammaticalization path from objective temporal meaning to subjective metadiscursive meaning in the line of Traugott's clines from propositional to textual meaning (1982) and from clause-internal adverbial to discourse marker (1997). We believe it should.

First, there is the impressive rise in frequency through the centuries which appears at least to interact with the grammaticalization of an item or construction. Second, we have shown that as far as the evolution from propositional meaning to discourse meaning is a case of grammaticalization, alors clearly follows this path (but see e.g. [START_REF] Waltereit | The rise of discourse markers in Italian: a specific type of language change[END_REF] for arguments against this view). Finally, alors fits very well into the scenario of grammatical change depicted by [START_REF] Heine | On the role of context in grammaticalization[END_REF], and seems to have reached the stage of conventionalization in Spoken PDF. This grammaticalization hypothesis, however, will need further perspectivization within the vast debate on grammaticalization.

Finally, there is the prominent variation between speech and writing in the semantic distribution of alors, which raises the issue of the role of speech in language evolution overall. In our view, speech plays a driving role in the evolution of language and therefore deserves a prominent place in grammaticalization research. Unraveling this specific role must, however, remain the topic of ongoing and future research.

  pointed out, alors only has temporal uses. In our corpus too, most occurrences are purely temporal, as in example (15): (15) Vos en iroiz a Kamaalot et demorroiz illuec jusqu'a mardi, car alors est li jorz a ma dame (La mort le roi Artu, 1230, p. 97) 'You will go to Camelot and stay there until Tuesday, for [alors] is the day of my Lady'

  alors typically expresses temporal concomitance; initial alors can function as a connective (cf. Le Draoulec & Bras 2007) expressing temporal succession, causal or conditional relations, or a metadiscursive meaning, especially topic shift. Final alors should express a metadiscursive meaning, especially intersubjectivity.

  Figure 7 confirms this hypothesis. The rise of metadiscursive use from 26 % in the written data to 63 % in the spoken data seems to go hand in hand with a kind of monopolization of topic shift and topic transition markers in initial position, together with causal (12 %) and conditional (9 %) connective uses. Temporal use having disappeared (2 %), the medial position is left almost empty (3 %), while the final position best mirrors the written situation, with only 13 % of the alors occurrences, mainly causal and conditional. Since the data present too few observations in medial and final position, no statistical conclusions can be drawn. The data, however, speak for themselves, showing that in the spoken data, too, there is a relationship between the semantic function of alors and the position it occupies in the sentence/clause: 84% of the data are in initial position where alors either marks topic shifts or smoother topic transitions in metadiscursive function, or marks a causal/conditional relation to the prior segment in connective function. A final word needs to be said about the occurrences in final position. In contrast to what we found in the written quoted speech data, we do not find any metadiscursive uses in the form of interjections in final position. What we do find are causal and conditional uses in the form of conclusions and/or requests for confirmation. A typical example is given in (19): (19) L1 ben oui je pense bien L2 ah il y avait des chambres inoccupées alors L1 ouais ouais 'L1 well yes I think so L2 oh there were unoccupied rooms alors L1 yeah yeah'

 8 Figure 8, in which the squared bars represent the total percentage of occurrences in the

  clause-internal use to a discourse-structuring, peripheral (clause-initial and clause-final) use in Spoken PDF. Our data suggest that the movement to clause-initial position was either a trigger or a precondition of the semantic and functional change of alors. There is indeed a clear link between position and meaning, for all periods where alors is polysemous. Besides, the rise of polysemy follows at least a few centuries after its shift in sentence position. It remains to be seen, however, if this link between position and Discourse Marker function is specific to French and English (cf.[START_REF] Traugott | From propositional to textual and expressive meanings: Some semantic-pragmatic aspects of grammaticalization[END_REF], or is a more general linguistic trend. A promising path of investigation could be to look at this relationship between meaning and syntactic position in terms of context-dependent constructions (see, for example,Bergs & Diewald 2008;[START_REF] Noël | Diachronic construction grammar and grammaticalization theory[END_REF]).

In our view examples (16-17) are crucial traces of an ongoing evolution from temporal to causal uses. It is important to recognize such an 'in between' category which we regard as indicative of semantic evolution.

  scenario for how a linguistic expression acquires a new grammatical meaning. In the initial stage, the context is unconstrained, resulting in the source meaning. This corresponds to the situation of alors 1 in Old French. The next step, called the bridging context, corresponds to the appearance of a new context giving rise to an inference in favor of a new meaning. This is what happens to alors in Middle and Classical French when it receives causal and conditional meanings in peripheral position (alors 2 and alors 3 ) -but also in

clause-internal position for Classical French! The "switch context" is the third step: the new context is incompatible with the source meaning. This is what happens with temporal concomitant alors 1 'at that time', which has become incompatible with peripheral position in Present Day French. "Conventionalization" is the final stage of Heine's scenario, where the "target meaning no longer needs to be supported by the context that gave rise to it

[and]

may be used in new contexts"

(2002:86)

. We would like to suggest that this is what is happening to alors in spoken PDF, where the source meaning temporal alors has nearly disappeared to leave room for the mainly metadiscursive uses of alors.
