This book demonstrates the importance of raising multilingual children in the UK, both for the children's own benefit and for the benefit of society as a whole. Against the backdrop of both the rich linguistic diversity already present in the UK and the challenges faced by any languages other than a few major European languages to find any space…

The first part of this paper discusses the rationale for universal grammar (UG) theory to explain first language acquisition. It also illustrates the issues of language acquisition Chomsky argued which could not be supported by behaviourist theories and shows how Chomsky proposed a solution to this problem through his theoretical model of…

The study of language acquisition has a long and contentious history: researchers disagree on what drives this process, the relevant data, and the interesting questions. Here, I outline the Starting Big approach to language learning, which emphasizes the role of multiword units in language, and of coarse-to-fine processes in learning. I outline…

Bilingual environments are more complex than monolingual environments. To adapt to this complexity, bilingual infants may navigate their environment in fundamentally different ways than monolingual infants. Drawing from visual, social, and linguistic processing, in this article, I present evidence to suggest that bilingual and monolingual learners…

As children of immigrants are increasing in number across the U.S. classrooms, schools need to develop strategies to engage with immigrant families. Structural and attitudinal issues in the school system create challenges in communicating with immigrant parents. Immigrant parents have high expectations for their children's academic achievement…

Uganda's "early exit" language policy positions African languages ambiguously in public education provision. Runyoro-Rutooro and Runyankore-Rukiga are spoken in Western Uganda in public spaces where translanguaging happens as a matter of course. These languages are heard at pre-primary and lower primary levels but are superseded by…

This article introduces this special issue by declaring that the studies contained here build on the idea that multilinguals, in the sense of learners or speakers that have more than two languages in their linguistic repertoire, are different from bilinguals and monolinguals in various ways. Several authors in the area of third language…

Researchers agree that attention to bilingualism and biliteracy can and should be a goal in all educational settings where young dual language learners are present. The challenge, however, is how to promote biliteracy development while remaining congruent with principles of developmental direction, specifically the idea that children's…

As humans, we all experience the fundamental need to belong. Often, this sense of belonging is inherited and nurtured by our families and their histories, the languages we speak and the cultures we adhere to; and it is in our experiences and engagement with these aspects of ourselves that our identities are formed, contested, negotiated and…

Research interest in heritage speakers and their patterns of bilingual development has grown substantially over the last decade, prompting sign language researchers to consider how the concepts of heritage language and heritage speakers apply in the Deaf community. This overview builds on previous proposals that ASL [American Sign Language] and…

When an adult migrant begins to acquire a second language, it is often presumed that the learner is already equipped with first language literacy and can therefore transfer these same literacy skills during their acquisition of the new, second language. However, many adult second language (L2) learners lack the opportunity to develop first…

A new solution is offered to the Infant Language Acquisition Problem, rejecting both of Chomsky's alternatives. It proposes that the infant does not acquire his mother tongue by mastering its grammar, whether by inference from personal experience or via an innate Language Acquisition Device such as the UG, but that the language he hears is all…

Bilingual education has unique and complex features. In the course of language study, with the mother tongue as a foundation, acquiring a second language depends on the features of student's learning and age. Based on the construction of J. Cummins's (1984) dual iceberg theory dual-language model, students' bilingual education is founded on the…

In this commentary, the author defends the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roepe (A&R) in the present issue. Topics discussed include second language acquisition, the concept of developmental optionality, and the idea that structural decisions involve the lexical dimension. The author states that A&R's…

This article offers the author's commentary on the Multiple Grammars (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue. Multiple Grammars advances the claim that optionality is a constitutive characteristic of any one grammar, with interlanguage grammars being perhaps the clearest examples of a…
