Multilingualism presents both a challenge and an opportunity for Natural Language Processing, with code-switching representing a particularly interesting problem for computational models trained on monolingual datasets. In this paper, we explore how code-switched data affects the task of Machine Translation, a task which only recently has started…

The paper focuses on the communication of three bilingual couples, each speaking a different lingua franca (LF). Positioning theory offers a methodological framework to explain language choice in interactive positioning within personal contacts. A comparative view of the couples' storylines benefits from the differences between them. The analysis…

The study investigates the reflections on tempo-aspectual morphology in Italian expressed by undergraduate multilingual learners with previous knowledge of Swedish and a Romance language (N = 22). The reflections of the participants, who were divided into four groups depending on a combination of proficiency in their background Romance language…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

This study sets out to investigate possible effects of previously learned languages on the acquisition of English as a third language by examining six prepositions (in, on, at, behind, over, to) when they denote spatial relations. Two picture description tasks were employed to find out which of the two known languages (L1 and/or L2) is the major…

Although previous research has observed a facilitative influence of the first language (L1) on the acquisition and processing of gender agreement in a second language (L2), particularly in language pairs with similar gender agreement marking, the question of whether knowledge of two languages with gender can confer an additional advantage for…

Quantificational elements such as some pose a challenge to young language learners, given their vague meaning and ability to take on an upper-bounded interpretation (relative to "all") in certain contexts. The challenge is enhanced when a child is acquiring multiple languages that do not share a one-to-one mapping between their lexical…

English for Academic Purposes (EAP) aims to equip multilingual students with the tools to effectively engage in disciplinary academic communication, especially writing. An ongoing challenge is how to transfer students' knowledge of language from the EAP classroom into their current and future disciplines (Monbec, 2018) and how to empower them as…

This paper compares the initial state of second language (L2) and third language (L3) acquisition for English articles to examine the influence of L2 proficiency on positive transfer from L2 to L3. We tested 36 L1 Turkish/L2 German adolescent learners of L3 English (L3 group), 41 L1 Turkish adolescent learners of L2 English (L2 group), and 10…

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers' knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential…
