Acquisition of L2 French Object Pronouns by Advanced Anglophone Learners

: The role native language transfer plays in L2 acquisition raises the question of whether L1 constitutes a permanent representational deﬁcit to mastery of the L2 morphosyntax and prosody or if it can eventually be overcome. Earlier research has shown that beginning and low intermediate Anglophone L2 French learners are insensitive to French morphosyntactic and prosodic constraints in using in situ pronouns transferred from the L1. The prosodic transfer hypothesis (PTH) proposes that native prosodic structures may be adapted to facilitate acquisition of L2 prosodic structure. Our study presents new evidence from three Anglophone advanced learners of L2 French that indicates ceiling performance for pronoun production (99% accuracy in 300 tokens over nine interviews) and grammaticality judgment (98% accuracy). This native-like performance demonstrates target French morphosyntax and prosody, built—as predicted by the PTH—by licensing pronominal free clitics in a new pre-verbal L2 position distinct from post-verbal L1. Furthermore, the learners’ data conﬁrms accurate prosody by way of appropriate prominence patterns in clitic + host sequences, correct use of clitics with preﬁxed verbs, use of stacked pronouns, as well as correct prosodic alternations involving liaison and elision. These results counter impaired representation approaches and suggest early missing inﬂection may be overcome.


Introduction
The role of the native language in L2 acquisition has been a topic of inquiry for decades (e.g., Lado 1957;Schwartz and Sprouse 1996) and is of particular interest in cases where the two languages differ in several dimensions.This notion of transfer raises the question of whether the native language constitutes a permanent representational deficit to mastery of the new morphosyntax (Hawkins and Chan 1997;Tsimpli and Dimitrakopoulou 2007) or if it can eventually be overcome (Lardiere 2007;Rothman 2011).In the arena of prosody, one proposal concerning native language influence is the prosodic transfer hypothesis (PTH, Goad and White 2006, 2008, 2009), which argues that learners' native language prosodic structures may be used to accommodate L2 functional material.
The acquisition of French pronouns is a challenge for Anglophone second language (L2) learners, since the two languages differ morphosyntactically and prosodically for object pronouns.In terms of morphosyntax, English pronouns are located in the canonical object position of the full noun phrase (1a, b) and may optionally be right-cliticized to the verb (1d).In contrast, French object pronoun clitics are left-adjoined to the inflected verb (2b), and are not in the canonical direct object position (2a, c).The acquisition of L2 Romance pronouns has been a subject of investigation to test morphosyntactic transfer hypotheses (White 1996;Hawkins and Franceschina 2004;Granfeldt and Schlyter 2004;Arche and Domínguez 2011) in studies that indicate that mastery of clitic pronouns varies substantially according to proficiency level. 1 Beginning learners of L2 French clearly transfer English structures in producing in situ pronouns as in (2c) (Herschensohn 2000;Hawkins 2001), while intermediate proficiency learners show transitional responses, both behavioral and cortical, to ungrammatical in situ pronouns (Sneed German et al. 2015).Little research has been done on advanced learners of L2 French with respect to object clitic pronouns. 2 Nor have object clitics been examined with respect to the prosodic transfer hypothesis.In terms of prosodic structure, English nouns and pronouns and French nouns constitute independent prosodic words, whereas French object pronouns constitute free clitics attached to the left of the verb, so that the prosodic structure of (2b) is as shown in (3c), where the clitic is attached as a sister to the prosodic word (PWd) and a daughter to the prosodic phrase (PPh) (Goad and Buckley 2006).English pronouns, normally independent prosodic words, may also cliticize, but as right-branching affixal clitics, so that the prosodic structures of (1a/b) and (1d) are as shown in (3a) and (3b) (Selkirk 1996). 1 Even early bilinguals may show variability.Perpiñán (2017) describes non target-like responses by Spanishdominant bilinguals for Catalan clitics non-existent in Spanish, indicating a divergent Catalan grammar despite very early exposure (before age four) to Catalan.
The French clitic is both directionally (left, not right) and prosodically (free, not affixed) distinct from the English pronominal clitic.In their nominal morphosyntax, however, both languages share a similar prosodic free clitic structure, that of the leftward article plus noun as in (4).

The availability of this structure is interesting, given the PTH's proposal that target L2 prosody can be built when L1 structures are licensed in new positions ("minimal adaptation", Goad and White 2004).
In this article, we explore implications of the PTH for Anglophone acquisition of L2 French clitics by examining new data from advanced learners with extensive experience in the target environment.The first background section describes French and English pronouns (Section 2.1), prosodic structure and the prosodic transfer hypothesis (Section 2.2), and previous research on the L2 acquisition of French clitics (Section 2.3), which leads to our research questions for advanced learners (Section 2.4).The next sections present new evidence from advanced learners of L2 French (participants and methodology described in Sections 3.1 and 3.2, respectively), coming from three case studies that include data on production and grammaticality judgments (results presented in Section 3.3).We discuss the new evidence in light of the PTH (Section 4), arguing that the data support the hypothesis in demonstrating the learners' shift to L2 French prosody.Our analysis adopts the concept of minimal adaptation of native prosodic structures to accommodate L2 functional material.We close with some brief concluding remarks (Section 5).

French and English Object Pronouns
Cross-linguistically, pronouns fall into strong, weak and clitic classes (Cardinaletti and Starke 1999).Strong pronouns project the most complex syntactic, semantic and phonological structure, followed by weak pronouns and finally by clitics. 3French pronouns include parallel sets of strong and clitic pronouns in six persons, while English pronouns are strong unless cliticized to the verb as in (1d) (Table 1).Strong pronouns in French and English are phonetically free standing and fully referential, whereas clitics in French are morphosemantically minimal (person, gender and number features) and structurally deficient, requiring phonological attachment to a host.Strong pronouns act like full determiner phrases (DPs) in French in that they are syntactically mobile and phonologically stressed.They, but not clitic pronouns, can appear in coordination (5), in isolation (6) and in prepositional phrases (7).They are quite frequent in left and right dislocation (8) and are usually animate/ human.and clitic pronouns in six persons, while English pronouns are strong unless cliticized to the verb as in (1d) (Table 1).Strong pronouns in French and English are phonetically free standing and fully referential, whereas clitics in French are morphosemantically minimal (person, gender and number features) and structurally deficient, requiring phonological attachment to a host.Strong pronouns act like full determiner phrases (DPs) in French in that they are syntactically mobile and phonologically stressed.They, but not clitic pronouns, can appear in coordination (5), in isolation (6) and in prepositional phrases (7).They are quite frequent in left and right dislocation (8) and are usually animate/ human.In contrast, clitic pronouns are unstressed, may not remain in situ, and refer to both animate and inanimate referents.Roberts (2010, p. 41) analyzes French clitics as "simultaneoulsy maximal and minimal elements", bundles of features (number, gender, person, case) in the head D of the Determiner Phrase in which they occur, whose defective nature requires cliticization to an inflected verb or infinitive.English strong pronouns resemble French ones in syntactic distribution and stress, as the translations indicate.The clitic forms differ between English and French, however, in terms of placement, morphological variation, feature specification, as well as prosody, as outlined in the next section.
To be able to use pronouns, Anglophone learners need to master the implicit knowledge that French object pronouns must be placed in non-canonical position to the left of the verb; that strong 4 Our focus here is on strong and clitic pronouns that are relevant for French and English.In Italian in Telefono a loro 'we phone them' the pronoun is strong, in Telefono loro it is weak, and in Gli telefono it is a clitic (Ordoñez 3 Romance clitic syntax has been discussed for decades within generative theory, beginning with Kayne (1975).See recent summaries by Roberts (2010) and Grüter (2008).Generally, there are two approaches, one group treating clitics as agreement markers on the verb (Grüter 2008;Culbertson 2010), and the other arguing that clitics must move from within the Verb Phrase (Kayne 1975;Roberts 2010;Cardinaletti and Starke 1999;De Cat 2005).4 Our focus here is on strong and clitic pronouns that are relevant for French and English.In Italian in Telefono a loro 'we phone them' the pronoun is strong, in Telefono loro it is weak, and in Gli telefono it is a clitic (Ordoñez and Repetti 2014).

To be able to use pronouns, Anglophone learners need to master the implicit knowledge that French object pronouns must be placed in non-canonical position to the left of the verb; that strong and weak pronouns are in syntactic complementary distribution (nominative and objective obligatory clitic); that French pronouns are marked for person, number and gender (as English), but that gender is grammatical, not semantic (and thus applies to every inanimate noun as well as animate).Learners also need to prosodically integrate object pronouns in a way compatible with L2 target structures.

Prosodic Structure
Which prosodic representations accommodate object pronouns in English and French?English object pronouns are typically realized as full prosodic words (9a), but may cliticize as right-branching affixal clitics (9b) (Selkirk 1996).
When an object pronoun in English is realized as a full prosodic word (9a), it attaches as a PWd sister to the verb, itself a PWd, with both of these linking to a phonological phrase node.A different structure is projected under phonological reduction of the pronoun.In this case (9b), failing to project its own PWd node, the pronoun is instead incorporated into an embedded prosodic word structure as a structurally deficient sister to the PWd verb.and weak pronouns are in syntactic complementary distribution (nominative and objective obligatory clitic); that French pronouns are marked for person, number and gender (as English), but that gender is grammatical, not semantic (and thus applies to every inanimate noun as well as animate).Learners also need to prosodically integrate object pronouns in a way compatible with L2 target structures.

In French, on the other hand, (as for all "morphologically-free functional items [in French] which precede their host" (Goad and Buckley 2006, p. 114)), object pronouns are prosodically left-branching free clitics (10).

The free clitic-which can be separated from its host by other elements-differs from its affixal counterpart by its direct relation to the PPh: "the function word is sister to PWd and daughter to phonological phrase" (Selkirk 1996).The English affixal clitic cannot be separated from its host (11), whereas the French free clitic can, as we see in examples involving clitic stacking in Tense Phrases (12).In French, on the other hand, (as for all "morphologically-free functional items [in French] which precede their host" (Goad and Buckley 2006, p. 114)), object pronouns are prosodically left-branching free clitics (10).and weak pronouns are in syntactic complementary distribution (nominative and objective obligatory clitic); that French pronouns are marked for person, number and gender (as English), but that gender is grammatical, not semantic (and thus applies to every inanimate noun as well as animate).Learners also need to prosodically integrate object pronouns in a way compatible with L2 target structures.

With respect to the free clitic structure in French, it is noteworthy that it is one which occurs in English, albeit in a different context-in article + noun sequences.In other words, English articles are, like French object pronouns, prosodically left-branching free clitics (13).Note that in both English and French, other elements may be inserted (e.g., adjectives) between the free clitic article and the head noun in the DP, just as clitics may be stacked before the verb in the TP.It is well known that articles are acquired before object clitics in L1A and L2A (Prévost 2009;Paradis et al. 2014).

Prosodic structure of English articles
According to the prosodic transfer hypothesis (Goad et al. 2003;Goad and White 2006, 2008, 2009), learners have difficulty with L2 prosody distinct from L1. Goad and White (2004, 2006, 2008, 2009) and Goad et al. (2003) study L1 Mandarin and L1 Turkish learners of L2 English to test the PTH with respect to distinctive L2 prosodic structures in the past tense (Mandarin does not mark tense and does not allow affixal prosody) and articles (neither Mandarin nor Turkish have articles and do not allow free affixes-left).The series of articles suggests that learners accommodate the L2 English prosodic structures either by omission (of tense or article) or by adapting an L1 prosodic realization.For example, some of the L1 Turkish participants (Goad and White 2009) used an L1-licit prosodic structure of a stressed article in L2 English (even when L2 stressing was not appropriate).This tendency is confirmed by Snape and Kupisch (2010) in their phonetic analysis (using Praat software, www.praat.org) of an L1 Turkish L2 English learner's article production in which she overused stressed articles.
We have seen that English pronouns vary in prosodic realization between prosodic words and affixal clitics-right, whereas French consistently requires object pronouns to be free clitics-left.The two languages differ, therefore, not only in the directionality of object clitic placement (driven by morphosyntax) but also in their prosodic structure (affixal vs. free clitics).The PTH offers a means by which a distinct new L2 prosodic structure might be built by licensing L1 structures in new positions ("minimal adaptation", Goad and White 2004).

6 Herschensohn (2004) reports on Chloe, one of the subjects of the current study, at an earlier stage of her L2 French acquisition, at which she makes numerous production and comprehension errors.The most prevalent errors in early interlanguage are the use of null pronouns (16)-similar to that of children acquiring French as an L1 (Hamann 2004;Hulk 2004;Paradis et al. 2014)-and in situ pronouns (15).Paradis et al. (2014, p. 170) note for L1A "regarding incorrect structures, over 90% were omitted objects".In situ French pronouns reflect native language transfer of English morphsyntactic structure, while null objects could represent a well-documented tendency to missing inflection and missing functional items (Prévost and White 2000;Lardiere 2007;Arche and Domínguez 2011).As learners advance in proficiency they show more native-like command of pronouns (Arche and Domínguez 2011;Cuza et al. 2013;Grüter and Crago 2012;Sneed German et al. 2015).
Acquisition of L2 Romance pronouns has been a subject of investigation to test morphosyntactic transfer hypotheses (Granfeldt 2005;Granfeldt and Schlyter 2004;Arche and Domínguez 2011).Impaired representation approaches (Snape et al. 2009) assume that adult learners will have persistent difficulties mastering grammatical (uninterpretable) features of an L2, and that the syntactic deficit will be represented by persistent morphosyntactic errors.In contrast, missing inflection approaches (Prévost and White 2000;Lardiere 2007) attribute morphological errors to other problems such as processing overload or prosodic difficulties.In any case, evidence from earlier studies indicates that mastery varies according to proficiency level: beginning learners of L2 French transfer from English in producing in situ pronouns, whereas intermediate learners show transitional responses, both behavioral and cortical, to ungrammatical in situ pronouns (Sneed German et al. 2015).
Sneed German et al. (2015) use both behavioral measures and event related potentials (ERPs) to investigate comprehension of object clitics by two groups of intermediate Anglophone learners of L2 French and native speakers.Event related potentials, which record electrophysiological cortical activity using scalp electrodes, have been used to determine reactions to language phenomena in real time, with temporal resolution to the millisecond (Friederici et al. 1993;Hagoort and Brown 1999;Osterhout et al. 2004Osterhout et al. , 2006;;Steinhauer 2014).Lexico-semantic and morpho-syntactic anomalies reliably elicit two distinct native responses, the N400 and the P600 respectively. 7For example, sentence (18b), would elicit a negative trending electrophysiological wave 400 ms after the event of interest (cream vs. batteries), compared to (18a).

Given extensive production data documenting Anglophone in situ L2 French pronouns, Sneed German et al. ( 2015) tested reactions to ungrammatical in situ strong and clitic pronouns (20a, b), as well as grammatical sentences (20c) that serve as a baseline.From a prosodic perspective, strong pronouns are licit in a stressed PWd position (20b), but they are morphosyntactically ungrammatical.In contrast, the in situ clitics (20a) are both morphosyntacitcally and prosodically illicit.Participants did two behavioral tasks (grammaticality judgments and general proficiency) and their cortical reactions were measured.The native French speakers showed predictable behavioral results (near ceiling accuracy) and a robust P600 to ungrammatical in situ pronouns, both strong and clitic.The high-intermediates' results were qualitatively similar in behavioral and ERP responses to natives and significantly better than lowintermediates.In contrast, the low-intermediates' results on the behavioral grammaticality judgments (GJ) task showed chance judgement of in situ clitics, (rejected 49% of the time), while ungrammatical strong pronouns were dismissed only 23% of the time, suggesting that lowintermediates are not sensitive to the ungrammaticality of these constructions. 9n important inference for further investigation concerns the response distinction between strong and clitic pronouns for the two groups of intermediates.Recall that the English pronoun system uses strong pronouns as the default and differs in morphosyntactic form and word order from the French system, in which object pronouns may only be clitic.Both groups of intermediates showed higher accuracy and more French-like cortical responses to the clitic violations than the strong pronouns.The less proficient group persists in their acceptance of prosodically licit strong pronouns, while showing an emerging implicit understanding of object clitics; one might conclude that while still apparently using their L1 English settings for pronoun placement, their cortical response demonstrates emerging sensitivity to French prosody.In particular, learners may be demonstrating sensitivity to the apparent prosodic deficiency of the clitic pronouns in L2 input.This in turn may be part of a general emerging sensitivity to French schwa (the vowel of highly frequent object clitics me, te, and le).If this is the case, part of leaners' higher intolerance for the clitic pronoun in situ results from an emergent awareness that the schwa vowel is incompatible with a prominent position.This may facilitate the acquisition of morphosyntax, while not necessarily driving it.
The more proficient group, while showing some residual behavioral acceptance of strong From a prosodic perspective, strong pronouns are licit in a stressed PWd position (20b), but they are morphosyntactically ungrammatical.In contrast, the in situ clitics (20a) are both morphosyntacitcally and prosodically illicit.Participants did two behavioral tasks (grammaticality judgments and general proficiency) and their cortical reactions were measured.The native French speakers showed predictable behavioral results (near ceiling accuracy) and a robust P600 to ungrammatical in situ pronouns, both strong and clitic.The high-intermediates' results were qualitatively similar in behavioral and ERP responses to natives and significantly better than low-intermediates.In contrast, the low-intermediates' results on the behavioral grammaticality judgments (GJ) task showed chance judgement of in situ clitics, (rejected 49% of the time), while ungrammatical strong pronouns were dismissed only 23% of the time, suggesting that low-intermediates are not sensitive to the ungrammaticality of these constructions. 9 An important inference for further investigation concerns the response distinction between strong and clitic pronouns for the two groups of intermediates.Recall that the English pronoun system uses strong pronouns as the default and differs in morphosyntactic form and word order from the French 7 For discussion, see Gouvea et al. (2010); Steinhauer et al. (2010). 8 Given the incremental appearance of the clitic le, the reader's first reaction to (20a) would be to process le as an article of an anticipated noun phrase.system, in which object pronouns may only be clitic.Both groups of intermediates showed higher accuracy and more French-like cortical responses to the clitic violations than the strong pronouns.The less proficient group persists in their acceptance of prosodically licit strong pronouns, while showing an emerging implicit understanding of object clitics; one might conclude that while still apparently using their L1 English settings for pronoun placement, their cortical response demonstrates emerging sensitivity to French prosody.In particular, learners may be demonstrating sensitivity to the apparent prosodic deficiency of the clitic pronouns in L2 input.This in turn may be part of a general emerging sensitivity to French schwa (the vowel of highly frequent object clitics me, te, and le).If this is the case, part of leaners' higher intolerance for the clitic pronoun in situ results from an emergent awareness that the schwa vowel is incompatible with a prominent position.This may facilitate the acquisition of morphosyntax, while not necessarily driving it.
The more proficient group, while showing some residual behavioral acceptance of strong pronouns, already were approaching the French natives in their responses to the ungrammatical in situ clitics.The research cited earlier on beginning and intermediate Anglophone learners of L2 French provides evidence that beginners and low intermediates transfer native pronoun word order, but with increasing proficiency, learners are able to gain mastery of L2 French morphosyntax, as indicated by comprehension, production and cortical measures.We infer that L2 learners can acquire features and word order different from the L1 system, but need to further investigate prosody.

Prosodic structure of English object pronouns English full pronouns are PWds under PPh, whereas their reduced clitic forms are affixal clitics right-attached to the PWd verb.In the early stages of L2A, the in pronouns that have been observed in production can be analyzed prosodically as PWd, as in (9a).There is no phonological evidence (phonological reduction or prosodic weakness) to suggest an affixal clitic (9b) analysis.In contrast, French object clitics are left free clitics under PPh, just as French and English articles are.
Beginning L2 French learners persist in Anglophone transfer with in situ placement; intermediate learners appear to gain prosodic sensitivity, distinguishing licit strong pronouns in situ from illicit clitics.We investigate advanced learners of L2 French pronouns to determine if they have adapted their object clitics to a French-like prosodic representation of left free clitics (left sister to PWd, daughter of PPh), or if they persist in using an English-like PWd structure (right sister to PWd).We pose the following research questions.

New Evidence from Advanced Learners
In this section we present L2 French data on production and GJ drawn from oral interviews with Chloe (age of acquisition onset 13), Eleanor (age of onset 17) and Max (age of onset 48), all post-puberty L2 learners.11As noted earlier, French object clitic usage can be problematic for L2 learners, as indicated by several studies cited in the previous section.We examine the use of French object clitics and strong pronouns in three interviews for each individual conducted before, during, and after a period abroad of seven to nine months (a total of nine interviews over a nine-month period).
The following section provides a description of the subjects and the data collection. 12

Participants
Max (age 59-60 at interview) began studying French at age 48, first on his own (completing the "French in Action" video program of first-year French) and later (with his wife Eleanor) with the help of a native French tutor who met with them one hour weekly for conversational exchanges over a period of 11 years prior.Eleanor (age 53 at interview) studied for six years in high school and college and at age 28 spent two months with a family in France.She and Max vacation annually in France and do extensive reading, independent vocabulary/grammar study, audio listening, and television viewing in French for 16-18 h per week at home.At the time of the interviews, Max and Eleanor were spending four months in Paris and three months in Lyon, where they had daily contact with French in a variety of contexts.Chloe, (age 22-23 at interview), studied French for nine years in high school and college; spent six months in a family in France at age 16 (Herschensohn 2001(Herschensohn , 2003) ) and four months in study abroad at age 20.Subsequently, she became an "assistante d'anglais" (English teaching assistant) in the French overseas department of Réunion for nine months.Table 2 summarizes these points.

Materials and Methods
Although the project was ostensibly longitudinal (over seven to nine months), the interviews showed that the learners were sufficiently advanced to have reached a fairly steady state, and so the differences among the interviews were rather minimal.No notable change was observed over time in the error rate (but Chloe's production increases over the nine month period), and for this reason, we have collapsed the results from the three interviews together.Interviews were conducted by one of the authors (who has been certified by the American Council on the Teaching of Foreign Languages), who informally evaluated the three as being at an advanced level according to the American Council on the Teaching of Foreign Languages (ACTFL) Guidelines (cf.http://www.actfl.org/i4a/pages/index.cfm?pageid=4236).All three were able to use a range of tenses and moods, to discuss hypothetical situations and to carry out conversations on abstract and theoretical topics.They nevertheless made errors, particularly of gender assignment and aspect (Herschensohn andArteaga 2009, 2016).Conducted in a university office or in the learner's residence in France, each interview included elicitations of the following areas: present tense, descriptions of everyday routines and environments; past and future tenses; hypothetical situations; role play including a problem (e.g., confronting a dry cleaner for damage or introducing a speaker at a lecture).The interviewer gave leading questions to carry forward the conversation, but it was the interviewees who provided most of the dialogue.
After the interview, subjects did written grammaticality tasks related to pronouns and other topics.The GJ task was adapted from Hawkins et al. (1993) and modified to have three versions for the three interviews.Comprising 50 sentences, half of which were ungrammatical, it had been used in the earlier studies reported (Herschensohn 2001(Herschensohn , 2003(Herschensohn , 2004;;Herschensohn and Arteaga 2007, 2009, 2016).It included sentences that targeted both pronoun use (20% of the sentences) and verb placement (80% of the sentences); representative sentences for the pronouns are included in Appendix A. Participants were asked to mark the sentences as G (grammatical), NS (not sure) or * (ungrammatical) and to correct the latter.
The data from the interviews were transcribed and checked for accuracy by three linguists fluent in French.The pronoun production data were coded and compiled by a graduate research assistant.The evidence was in the present case evaluated for all obligatory contexts of non-nominative pronouns, and for all uses of non-nominative pronouns, which were coded as strong or clitic.The production data from the nine interviews included 17,000 words, of which 217 were object clitics and 91 strong pronouns.

Results from Production and Grammaticality Judgments
The evidence from the interview production and the grammaticality judgments indicates near ceiling performance on object pronoun production and the grammaticality judgment task.Table 3 documents the suppliance in obligatory contexts (the denominator in Table 3) of the 217 accurate object clitics, Table 4 portrays the correct use of the 91 strong pronouns (plus one error), while Table 5 gives the results of the GJ task.The three interviewees produced no prosodic errors of clitics in situ or strong pronouns as preverbal; more importantly, they produced consistent and accurate elision and liaison of function words, indicating ease with the L2 prosodic alternations (Tables 3 and 4).As for the strong pronouns, most were used in PPs (obligatory suppliance indicated in Table 4 as the denominator); in addition, the three participants used freestanding strong pronouns (indicated by "+" in the table; these were supplemental, not required).These correct tokens numbered 91.Eleanor mistakenly used tu for toi in interview II (23), that is the additional "+*1" indicated in her Interview II column.The errors include mainly lexical errors (21b, the verb dire 'to say' requires an indirect object clitic, not a PP complement), and two case reversals on the object clitics (22b, c).Eleanor misaligns her negative clitic ne (21a) and misuses strong and clitic pronouns (21b, 24).The word order error in 21a is noteworthy in that the object clitic is placed (and "stacked") to the left of the negative clitic particle ne-a placement incompatible with an affixal clitic analysis of object pronouns on the part of this speaker.
As the first section has shown, beginning and intermediate Anglophone learners of L2 French transfer native pronoun word order, but the evidence here indicates that these advanced learners appropriately use pronominal morphosyntax and word order.The pronominal errors produced by As for the strong pronouns, most were used in PPs (obligatory suppliance indicated in Table 4 as the denominator); in addition, the three participants used freestanding strong pronouns (indicated by "+" in the table; these were supplemental, not required).These correct tokens numbered 91.Eleanor mistakenly used tu for toi in interview II (23), that is the additional "+*1" indicated in her Interview II column.The errors include mainly lexical errors (21b, the verb dire 'to say' requires an indirect object clitic, not a PP complement), and two case reversals on the object clitics (22b, c).Eleanor misaligns her negative clitic ne (21a) and misuses strong and clitic pronouns (21b, 24).The word order error in 21a is noteworthy in that the object clitic is placed (and "stacked") to the left of the negative clitic particle ne-a placement incompatible with an affixal clitic analysis of object pronouns on the part of this speaker.

Our three learners show no evidence of prosodic prominence (stress) on object clitics that are preverbal; the only pronouns used in the stressed position (freestanding and in PPs) are strong pronouns.We therefore eliminated the PWd analysis (which may be appropriate for beginning learners who transfer in situ pronouns from English).As we saw earlier, the advanced learners' GJs all indicated rejection of in situ clitics and across the board acceptance of properly placed object clitics.Furthermore, Max, Eleanor and Chloe show evidence of stacked pronouns (see Appendix B) as in (26).

sequences? RQ4.
Do advanced Anglophone learners of L2 French produce object pronouns before verbs with prefixes?Do Max, Eleanor and Chloe indicate in their use of L2 French pronouns that they have adapted their object clitics to a French-like prosodic representation of left free clitics (left sister to PWd, daughter of PPh), or do they persist in using the English-like PWd structure (right sister to PWd)?As discussed earlier, if the clitics are never stressed, the PWd analysis is eliminated, and if clitics are "stacked", or used prefixed verbs, the affixal analysis is invalid.

The accuracy of both production and comprehension (GJs) indicates mastery of the L2 French morphosyntax of clitic pronouns.As Arche and Domínguez (2011, p. 305) note, "if learners have acquired the morphosyntactic properties of Spanish clitics, then high rates in both the production and comprehension tasks will be observed."We answer the first question in the negative, as the learners have overcome the transfer of English word order and morphosyntax; their only errors are lexical.We consequently see no impaired representation of their L2 syntax with respect to the use of strong and clitic pronouns in French.Although beginning and low intermediate French L2 learners make persistent errors with in situ clitics in behavioral responses and non-native neural responses, advanced Anglophone learners of L2 French master French pronoun word order and morphosyntax.These advanced learners demonstrate target-like mastery of French pronoun word order and prosody in production, and sensitivity to ungrammatical uses in grammaticality judgments.Similarly to Gabriele et al. (2013, p. 225) observations, we believe "our results show that by an advanced level of proficiency, learners can process features not instantiated in the native language similarly to native speakers".
As for prosodic stucture, recall that English pronouns vary in prosodic realization between prosodic words and affixal clitics-right, while French consistently requires object pronouns to be free clitics-left.However, we noted the availability of leftward free clitics in both L1 and L2 DPs.It is our point that learners are incapable of gaining the free clitic construction for French clitic pronouns for quite a long time.Anglophone learners are able to gain free clitic articles at the beginning and intermediate stages, so the free clitic prosodic structure is presumably available to beginning-intermediate learners in L1 English and L2 French articles (which are morphologically identical to third person clitic pronouns).The difficulty that the Anglophone learners have with French object pronouns is clearly not a difficulty with the prosody at the beginning and early intermediate stages, since they master the article plus noun left-clitic structure early on (indeed, they can simply transfer the L1 to L2 DP prosody).Our point is that a combination of factors that differentiate English and French pronouns-the contrasts noted by Cardinaletti and Starke (1999) in terms of semantic, morphological, syntactic and phonological properties-seem to converge to inhibit command of French object pronouns by early Anglophone learners.We propose that it is not until high intermediate (cf. Sneed German et al. 2015) and advanced levels that learners finally gain the implicit mastery that enables them to transfer this article free clitic prosody from DP to TP.Despite its availability, the beginning and intermediate learners were unable to adapt that structure to TP in L2 French.Eventually, though, at the advanced level, learners attain the ability to adapt the DP structure of prosodic free clitics to the TP domain, supporting the PTH (transfer of the L1 free clitic article) and the related concept of minimal adaptation (adapting the DP clitic to a TP domain) of native prosodic structures to construct the new L2 structures.The prosodic transfer hypothesis maintains that target prosody can be built when L1 structures can be licensed in new positions, and it is clear that the advanced learners have mastered the leftward clitics, licensing the pronominal objects in L2 preverbal instead of L1 postverbal positions.A lack of stressed preverbal clitics, together with the presence of stacked clitics and clitics before prefixed verbs, that the correct surface word order corresponds to the correct prosodic structure as well; the clitics are prosodified as free clitics, and not as PWds or affixal clitics.
Together with previous research, our results show that target prosody achieved via minimal adaptation, that is the transfer of the free clitic construction (article + noun) to a new context (pronoun + verb), cannot take place in an immediate transfer, but rather, a certain threshold of proficiency must be reached before the prosodic structures are adapted.Morphosyntax and prosody must apparently develop in parallel.

Conclusions
Beginning and low intermediate Anglophone L2 French learners are insensitive to French prosodic constraints in using in situ pronouns transferred from the L1, as proposed by the prosodic transfer hypothesis. 14The PTH proposes that native prosodic structures may be adapted to facilitate the acquisition of L2 prosodic structure.This study has presented new evidence from three Anglophone advanced learners of L2 French that indicates ceiling performance for pronoun production (99% accuracy in 300 tokens over nine interviews) and grammaticality judgments (98% accuracy).This native-like performance demonstrates that target French morphosyntax and prosody, are built-as predicted by the PTH-by licensing pronominal free clitics in a new pre-verbal L2 position distinct from post-verbal L1.Furthermore, accurate prosody is confirmed by correct pronoun placement, pronoun use in stacked sequences and with prefixed verbs, as well as target-like production of prosodic alternations (liaison, elision) in the learners' data.These results counter impaired representation approaches and suggest that early missing inflection may be overcome.
) point out two conditions for minimal adaptation: "(a) when they [structures] can be built through combining pre-existing (L1) licensing relations; or (b) when they involve L1 structures being licensed in new positions.
