The present study assesses linguistic and geographic diversity in selected outlets of SLA and multilingualism research. Specifically, we examine over 2,000 articles published in specialized top-tier journals, recording the languages under study and their acquisition order, author affiliations, the country in which the research was conducted, and…

This special issue revisits a classic topic in linguistic theory, A-bar movement, applied to developing and bilingual grammars. We claim that A-bar movement, or filler-gap dependencies, is still the quintessential linguistic phenomenon to illustrate the interaction between the biological endowment, the experience with language (past and present),…

This paper gives an account of the impact of spaces of linguistic non-understanding and spaces of linguistic partial understanding in the first author's linguistic ethnographic doctoral study of lawyer-client communication within UK immigration legal advice meetings. The paper uses the researching multilingually framework as a lens for exploring…

Research on Spanish heritage language (SHL) education has grown exponentially in the last two decades. The most recent nationwide study on SHL programs in US postsecondary institutions was conducted a decade ago. To continue this line of research, the primary aim of this study is to provide an update about the current state of SHL course offerings…

Language teachers report having limited direct contact with research and research findings despite generally positive perceptions of research (Borg 2009; Marsden and Kasprowicz 2017; Nassaji 2012). Key reasons teachers give are 1) practical - a lack of time and access, and 2) conceptual - academic papers can be difficult to read (Plavén-Sigray et…

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.…

Does complexity make multilingualism special? Since there is no unequivocal notion of complexity on which researchers agree, several characteristics that have been considered crucial for complexity are brought to bear on multilingualism. While multilingualism is fairly complex in some senses, for instance, because it requires that many variables…

In today's globalised world, a single named language such as English, Norwegian or Spanish, no matter how 'big' it is, rarely satisfies all the needs of communication, cooperation, education or any other area of human life. Neither is the entire language repertoire plausible for everyday use, simply because it is impossible to use too many…

In our article, we investigate the complex dynamics of linguistic understandings and mis- or non-understanding within multilingual contexts. Through the lens of sociolinguistic exploration, we navigate the multifaceted landscapes of language use, applying a multi-perspective approach and the triangulation method to explore the depths of linguistic…

There has been increasing L3 research on L3 transfer selectivity, especially concerning which factor triggers crosslinguistic influence during L3 acquisition. According to Slabakova's (2016) Scalpel Model, every linguistic property has distinct and unique input factors regarding L3 acquisition such as high/low frequency or positive/negative input.…

Research on multilingualism and the acquisition of language(s) faces numerous challenges given its inherently interdisciplinary character. This discussion will focus on the notion of internal context, a concept that forcefully demonstrates the need for integrating linguistically-oriented research with cognitive research in general. Investigating…

In this commentary, I question Westergaard's argument that third language (L3) data can be used to decide between theories such as Full Transfer Full Access, involving wholesale transfer initially, and Full Transfer Potential, involving property-by-property transfer. I suggest that much L3 data will be amenable to explanation under either theory.…

Language is on display all around us, all the time, and the study of this linguistic landscape is one of the fastest-growing areas of research in applied linguistics. This book provides an overview of how the field of Linguistic Landscape Studies has emerged and developed over the past 20 years, combined with an in-depth exploration of the…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

Globally classrooms are increasingly linguistically diverse. Research often oversimplifies lived linguistic heterogeneity as binary variables: native versus non-native. Linguistic distance (LD) measures allow a fine-grained operationalization of linguistic diversity in foreign language education. This study investigated associations of cognate LDs…
