Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

This article analyzes the construction of sign names in an emerging sign language from Mexico, the Yucatec Maya Sign Language (YMSL). Data comes from elicited interviews as well as natural interactions collected by the authors and signers from two different villages, Chicán and Nohkop. Despite YMSL being an isolate language, sign name construction…

In this commentary to Westergaard (2021), we focus on two main questions. The first, and most important, is what type of L3 data may be construed as supporting evidence--as opposed to a compatible outcome--for the Linguistic Proximity Model. In this regard, we highlight a number of areas in which it remains difficult to derive testable predictions…

With the increasing consensus that a single effect of bilingualism is unlikely, some scholars shift their focus to elements that may exert an influence on the bilingual brain. One such element that has been garnering attention lately concerns the role of L1-L2 typological distance. In this conceptual analysis, I make the case that the foundations…

We evaluated external and internal sources of variation in second language (L2) and native language (L1) proficiency among college students. One hundred and twelve native-English L2 learners completed measures of L1 and L2 speaking proficiency, working memory, and cognitive control and provided self-ratings of language exposure and use. When…

This commentary discusses the recent keynote article in "Second Language Research" by Westergaard (2021), which extends the Micro-cue Model to second language (L2) and third language (L3) acquisition. The commentary comments on such questions as: What makes a given property easy or hard to acquire? How do learners determine similarity?…

This paper looks into the dilemma of what counts as a grammatical 'learner error' in ELT on the basis of recent results from English variationist research and English as a lingua franca research. Examples from these studies show that features often perceived as 'errors' for EFL speakers also occur in ESL production--where they are called…

In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

This text comments on the Keynote article 'Microvariation in multilingual situations: The importance of property-by-property acquisition' by Marit Westergaard, who argues for Full Transfer Potential within the Linguistic Proximity Model in third language (L3) acquisition. The commentary points at some theoretical and methodological issues related…

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…

The major aim of the current paper is to review and discuss three prevailing approaches to the study of Second Language Acquisition (SLA) since the middle of the twentieth century: Contrastive Analysis (CA, henceforth), Error Analysis (EA) and Interlanguage (IL). It begins with a general overview of how the CA approach was formulated and developed…

This commentary discusses the recent keynote article by Westergaard (2021), which is an interesting contribution to the field of language acquisition and multilingualism, especially because it attempts to provide a wider perspective by embracing first, second and third language acquisition. I address major claims put forward by Westergaard, to…

This paper provides an introduction to Lakurumau, a previously undescribed and undocumented Oceanic language of Papua New Guinea. The first part of the paper is a guide to the Lakurumau documentation corpus, deposited in the ELAR archive. The participants and the content of the deposit, the technology used for recording, and the ethical protocols…

The field of English language teaching and learning has long been full of a plethora of acronyms and terms. Those terms that relate to languages and users of languages that are not those privileged or dominant in any given context should be subject to particular scrutiny. The author argues that labels applied to individuals and less dominant…

Though California's English Learner (EL) policies were developed in response to civil rights struggles for language access and equal educational opportunity, they are also conditioned by the history of U.S. settler and overseas conquest. This article presents a Critical Policy Analysis (CPA) of the California EL classification policies and…
