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…

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…

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…

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…

This dissertation investigates the methods used by intermediate, advanced and superior level learners of German when quoting formerly uttered speech in direct discourse. The study shows that that there are different methods of speech reporting at different levels of language proficiency. Each level of speakers in the study used the quotative…

This dissertation investigates the acquisition of oblique relative clauses in L2 Spanish by English and Moroccan Arabic speakers in order to understand the role of previous linguistic knowledge and its interaction with Universal Grammar on the one hand, and the relationship between grammatical knowledge and its use in real-time, on the other hand.…

This study of L-2 Russian interlanguage production examined the salience of phonetic, lexical and syntactical features for L-1 listener intelligibility, based on L-2 recitation of written scripts (Part I) and also unrehearsed speech (Part II). Part III of the study investigated strategies used by native-speaking teachers of Russian as a Second…
