The present systematic review examines what factors determine when, how and to what extent previous linguistic experience (from the first language, second language or both languages) affects the initial stages and beyond of adult third language (L3) acquisition. In doing so, we address what a bird's eye view of the data tells us regarding…

Multilingual research could offer a unique perspective on how the languages already acquired by a person affect the online processing of a new language. But it is currently difficult to assess this issue because theoretical accounts of multilingualism have focused on acquisition rather than processing and most empirical research to date has…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

This commentary discusses Westergaard's (2021) keynote article, which presents a comprehensive model of first language (L1), second language (L2), and third language (L3) acquisition. The commentary presents evidence from a previous study of L3 learners that provides support for Westergaard's property-by-property transfer proposal. The commentary…

This article updates the trends and developments of Japanese as a second language (JSL) research since Mori and Mori (2011) by reviewing nearly 200 selected empirical studies published in English or Japanese between 2010 and early 2019. The first section of this review examines the cognitive aspects of second language (L2) Japanese development,…

This thesis examines the role of the African substrate languages in the emergence of Atlantic Creole grammatical structures. Alleyne (1980) and Faraclas (1990) have convincingly demonstrated that a survey of the grammatical features that typify the Colonial Era English-Lexifier Creoles of the Atlantic reveals remarkable similarities with those…

Language attrition research has developed in several clearly delimited phases spanning, roughly, each of the three decades between 1982 and 2012 (see Kopke & Schmid 2004 for a more detailed overview and analysis). The first phase was an era of stocktaking, with a number of symposia, collected volumes and special issues of journals. All of…

This study considers the upper limit of ultimate attainment in the L2 French and L3 English of trilingual learners. The learners are native speakers of Moroccan Arabic who started learning L2 French at eight and L3 English at 16. They are advanced in both languages. Four constructions representing the verb movement and null subject parameter were…

The aim of this article is to give an up-to-date picture of study of the role of the background languages (the first language, L1, and the second language, L2) in third language (L3) acquisition, mainly in the two areas of vocabulary and syntax. These seem to be the two linguistic levels on which there has so far been most research concerning…

Several studies on L3 lexicon, and recently also some on L3 syntax, have convincingly shown a qualitative difference between the acquisition of a true L2 and the subsequent acquisition of an L3. Some studies even indicate that L2 takes on a stronger role than L1 in the initial state of L3 syntax (e.g. Bardel and Falk, 2007; Rothman and Cabrelli…

The present article addresses the following question: what variables condition syntactic transfer? Evidence is provided in support of the position that third language (L3) transfer is selective, whereby, at least under certain conditions, it is driven by the typological proximity of the target L3 measured against the other previously acquired…

This article presents the concept of Jewish Lithuanian as a range of post-Yiddish varieties spoken by some Jews in Lithuania and seeks to synthesise findings in contemporary ethnolect studies and in the field of Jewish language research. The legitimacy of the term "ethnolect" is questioned by some researchers; however, it is argued that…

One central question in the formal linguistic study of adult multilingual morphosyntax (i.e., L3/Ln acquisition) involves determining the role(s) the L1 and/or the L2 play(s) at the L3 initial state (e.g., Bardel & Falk, Second Language Research 23: 459-484, 2007; Falk & Bardel, Second Language Research: forthcoming; Flynn et al., The…

This volume collects empirical studies applying Conversation Analysis to situations where second, third and other additional languages are used. A number of different aspects are considered, including how linguistic systems develop over time through social interaction, how participants 'do' language learning and teaching in classroom and everyday…

Many factors that contribute towards the perception of second language (L2) sounds and the subsequent establishment of L2 phonetic categories have been the focus of past research. However, learning a third language, unlike SLA, may be influenced by additional factors attributed to the presence of two language systems in a bilingual instead of one…
