The system of second person singular forms of address (2PS) in Medellín, Colombia is tripartite consisting of "tú, vos," and "usted," while also including the existence of a dual "usted." The current study compares usage of the intimate "usted" versus the distant "usted" with data from an oral…

This article sheds light on the linguistic and extralinguistic conditions that determine the likelihood of L1 grammatical attrition in late sequential bilinguals. We explore whether aspectual interpretations associated with the present tense may be a vulnerable area for the native grammar of 30 late Spanish-English bilinguals who have settled in…

The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

A surprising comprehension-production asymmetry in subject-verb (SV) agreement acquisition has been suggested in the literature, and recent research indicates that task-specific as well as language-specific features may contribute to this apparent asymmetry across languages. The present study investigates when during development children acquiring…

Today's changing sociolinguistic reality of English calls for a shift in paradigm in the field of English language teaching. Therefore, this study aims to examine Moroccan EFL learners' (MEFLLs) attitudes towards World Englishes (WE) and native and non-native English-speaking teachers (NESTs & non-NESTs). Firstly, building on the assumption…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

This dissertation explores Spanish copular verbs, "ser" and "estar" (both 'to be' in English), in pre-adjectival contexts within two Spanish varieties: first-language (L1) Chilean speakers from Santiago (N = 29) and second-language (L2) English-speaking learners studying in Chile (N = 31). Bridging sociolinguistics and second…

Traditionally, Basque has three voiceless affricates that are different in their place of articulation. More precisely, affricates can have a lamino-alveolar, apico-alveolar, and prepalatal place of articulation and the graphemes used to represent them are respectively. Likewise, Basque has been described as having three fricatives with the same…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

This research project sought to explore the influence of English L2 on Spanish L1 in an environment where the L1 (Spanish) is the dominant language. Participants were recruited through voluntary response sampling at the University of Puerto Rico Secondary School (UHS). They completed a language survey on Google Forms that collected general…

This study investigates how fluent second-language (L2) learners of English produce and perceive the /ae/-/?/ vowel contrast of Southwestern American English. Two learner groups are examined: (1) early, proficient English speakers who were raised by Spanish-speaking families but who became dominant in English during childhood and, as adults, lack…
