Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

This study revisited L2 morpheme development order among Korean young learners of English. Taking into account the spirit of the current English curriculum in South Korea, the current study examined L2 morpheme development from two different perspectives: accuracy and fluency aspects. In the field of second language development, many studies have…

Learning to use prepositions in English as a second language (L2) has been widely acknowledged to pose significant difficulties to learners, especially within metaphorical contexts. Difficulties relate to the complex distributional patterns of prepositions in discourse, namely, the variety of collocations requiring their use, as well as…

Writing proper English sentences poses a significant challenge for Arabic-speaking postsecondary students studying English as a Foreign Language (EFL) due to substantial differences between Arabic and English syntactic structures. This basic qualitative study explored the perceptions of Arabic-speaking EFL learners at an Arabian university…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Second language (L2) phonological acquisition involves learning novel target-language sounds, variable forms of sounds that arise in different phonological contexts, and any phonotactic constraints that govern their appearance. Interlanguage (IL) grammars must adapt to represent sounds and constraints that are novel to the native language (L1)…

A great deal of research concerning the acquisition of English morphology as a second language has been carried out in order to explain some typical stages in the acquisition of the English-s morphemes and the difficulty confronted by second language learners. According to Siegel (2003), interlanguage and functional transfer both play a crucial…

In the past century, French has shifted from being the native language of many Louisianans to being an endangered dialect. Since the creation of the state agency CODOFIL (Council for the Development of French in Louisiana) in the 1960's, efforts have been made to revitalize French in Louisiana, and since the 1980's, some parishes have offered…

Adult second language (L2) learners often experience difficulty producing and perceiving non-native phonological contrasts. Even highly proficient bilinguals, who have been exposed to an L2 for long periods of time, struggle with difficult contrasts, such as /r/-/l/ for Japanese learners of English. To account for the relative ease or difficulty…

As face-threatening speech acts, requests are of particular interest to second language acquisition scholars. They affect the interlocutors' public self-images, and thus require a careful consideration of the social distance between the interlocutors, their status, and the level of the imposition, factors that are weighed differently in…

This study investigated the acquisition of the Spanish clitic se by English native speakers in passive, middle, and impersonal constructions. Little research has been done on this topic in SLA within a UG framework (Bayona, 2005; Bruhn de Garavito, 1999). VanPatten (2004) proposed the Processing Instruction (PI) model arguing for the necessity of…

The new developments in syntactic theory under Minimalism reconsiders the relation between the language faculty and general cognitive systems whereby language acquisition is accomplished by the interaction of Chomsky (2005)'s three factors: (F1) a minimally specified UG (Genetic endowment); (F2) Primary Linguistic Data (PLD), i.e., input; and (F3)…

This dissertation explores the second language acquisition of Mandarin Chinese tones by speakers of non-tonal languages within the framework of Optimality Theory. The effects of three L1s are analyzed: American English, a stress-accent language; Tokyo Japanese, a lexical pitch accent language; and Seoul Korean, a non-stress and non-pitch accent…
