This dissertation investigates the extent to which bilingual speakers' cognitive representations of the syntactic structures of their two languages are interconnected. This is a substantially understudied domain despite the widespread existence of bilingual/multilingual communities in the world, including the US. To draw solid conclusions about…

We investigate sensitivity to island constraints in English native speakers and Najdi Arabic learners of English, examining (1) whether second language (L2) learners whose native language (L1) does not instantiate overt "wh"-movement are sensitive to island constraints and (2) the source of island effects. Under a grammatical account of…

This article offers a descriptive account of seven interjections, "eish", "yho", "tjo", "sho", "hayi", "hau", and "mxm", which are adopted from different local South African languages into South African English. It investigates the frequencies, orthography, syntactic position,…

This corpus-based multifactorial study delves deeper into the well-known alternation between bare and full infinitive complements, specifically regarding the "help" concordances. It extends the line of research to learners' language productions with a focus on comparing and contrasting the probabilistic grammatical knowledge reflected in…

Artificial Intelligence (AI) powered translation influxes in the translation industry. Yet, questions have arisen about the quality of AI-powered translation systems (AIPTSs). Therefore, this study aims to evaluate the translation quality generated by ChatGPT for the Farewell Sermon. Using House's (2015) model of translation quality assessment…

This article reports on an empirical study of L3 Mandarin, aiming to shed light on transfer effects and their interaction with other factors throughout the L3 acquisition trajectory. A fill-in-the-blank task was employed to examine L2 and L3 acquisition of three types of Mandarin sentence-final particle clusters. Participants in the study were…

After the pandemic has ceased, high expectations have been raised for the tourism industry to generate quick and substantial income for Thailand as a remedy for the sluggish economy. The Tourism Authority of Thailand (TAT) plays a key role in informing and inviting foreign tourists to visit the country. TAT's official English website is another…

Children who speak non-standardized language varieties are at risk for both over- and under-referral to speech-language and special education services (e.g., Morgan et al., 2016; Pearson et al., 2014). Extensive research with bidialectal (Craig, 2016; Kohn et al., 2021) and bilingual (Goldstein, 2022; Paradis et al., 2021) children has shown the…

The current study examined early grammatical marking in a relatively understudied language, Mandarin, by using the Mandarin version of MacArthur-Bates Communicative Development Inventory. Two waves of data collection included 338 monolingual children (17-36 months; 143 female) at Time 1 and 308 children (32-55 months; 139 female) at Time 2 and…

All accounts of language acquisition agree that, by around age 4, children's knowledge of grammatical constructions is abstract, rather than tied solely to individual lexical items. The aim of the present research was to investigate, focusing on the passive, whether children's and adults' performance is additionally semantically constrained,…

Previous work has reported that children creatively make syntactic errors that are ungrammatical in their target language, but are grammatical in another language. One of the most well-known examples is "medial wh-question" errors in English-speaking children's wh-questions (e.g., "What do you think who the cat chased?" from…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

Each language has its unique way to mark grammatical information such as gender, number and tense. For example, English marks number and tense/aspect information with morphological suffixes (e.g., -"s" or -"ed"). These morphological suffixes are crucial for language acquisition as they are the basic building blocks of syntax,…

The study deals with emphatic constructions in English and Arabic scientific texts. To the researcher's best knowledge, this topic received little attention from linguistic researchers, exceptionally in functional grammar analysis. The importance of this study arises from the fact that some syntactic forms are effective linguistic choices for…
