Pidgins, narrowly defined, are auxiliary languages reserved for communication with linguistic outgroups. Although implicitly recognized as a class of languages by many linguists, there has been little systematic typological investigation of pidgins. This dissertation presents the first large-scale typological study of morphology and functional…

Increasingly, speakers of minoritized languages around the world are becoming uprooted due to economic pressures, political forces, and environmental destabilization. As communities leave their traditional homelands, they often experience accelerated language shift. Although youth are in a critical position to further transmit their languages to…

The founding and inception of Coral Way's bilingual program marked the beginning of Miami's multilingual era, as well as the start of modern bilingual education in the U.S. As multilingual and multicultural Miami has evolved, bilingual programming has not remained a priority in the school district. This dissertation study examines how language…

Sociolinguistic variation (SLV) entails that language is affected by social context (i.e. register, pragmatics). Interest in the acquisition of sociolinguistic variation in a second language (L2-SLV), as a key component of communicative competence, has grown exponentially over the past thirty years (Geeslin & Long, 2014). Researchers have…

This research investigated how a Critical Sociocultural Linguistics Literacy (CriSoLL) approach to authentic materials supports student literacy in a mixed Spanish heritage language (SHL) and additional language (L2) Spanish intermediate course at the university level. Using a qualitative approach (Cho, 2018; Esposito & Evans-Winters, 2021)…

Language forecasting, i.e., predicting the future state of a language, has long been regarded with a fair amount of skepticism. This is partly due to language change often being considered sudden, random, unpredictable, and viewed as the result of complex interacting factors that are not well understood (e.g., Keller 1994:72; Bauer 1994:25; Labov…

This dissertation examines the linguistic behavior of code-switching in three groups of highly proficient Cantonese-English bilinguals. Code-switching refers to alternating between two or more languages within the same sentence or between two sentences. While traditional research on bilingualism often compares bilingual speakers against…

In this three-paper dissertation project, I explore how 'English' becomes a recognizable object within the context of adult ESOL education. Building on scholarship on named languages (Garcia, 2019; Makoni & Pennycook, 2006), the historical construction of languages (Bonfiglio, 2010; Irvine & Gal, 2000), and raciolinguistic ideologies…

This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…

To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

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…

Following the social turn in Second Language Acquisition (SLA) in the 1990s (Block, 2003), researchers have increasingly focused on the emic perspective of learners. As a result, identity, subjectivity, and agency have come to the forefront in SLA research. In an effort to afford learners the means to negotiate meaning more freely and to position…

While much of the existing literature on code-switching focuses on languages that differ typologically, this dissertation focuses on typologically similar languages. Code-switching between Mandarin and Taiwanese is examined through the perspectives of 1) sociolinguistics, 2) typology, 3) phonetic and phonological production, and 4) speech…

*English Learners in secondary school settings often face discrepancies in opportunities and outcomes. Methods to address these discrepancies are grounded in an instrumental approach to instruction, wherein educational practitioners are understood to require methodological intervention in the form of professional development by a more experienced…

This dissertation investigates the interaction of developing extralinguistic cognitive systems with early language learning and processing through the case study of verb argument structure. The interaction of these systems with the linguistic system underpins fundamental theories of language learning and use: language does not exist in isolation.…
