An authoritative overview of research into heritage language acquisition, covering key terminological and empirical issues, theoretical approaches, and research methodologies.

Heritage speakers are a fascinating group of bilinguals with a unique profile. Living abroad as immigrants of the second generation, they speak the language of their own speech community (the heritage language) at home, and the societally dominant language in most other domains. What exactly they know about their heritage language continues to fascinate the research community as well as teachers and other practitioners working with this group. The different contributions cover a large variety of studies into heritage languages spoken in Europe and North America (including Chinese, Norwegian, Russian, Spanish and Turkish). The volume makes a key contribution to the description and explanation of variability in the outcomes of heritage language acquisition, taking into account a wide range of factors which impact on language acquisition. As comparisons are frequently made with monolinguals and foreign language learners, the volume is also highly relevant for researchers working in monolingual language acquisition and foreign language learning and teaching.

This volume is the first handbook dedicated to language attrition, the study of how a speaker's language may be affected by crosslinguistic interference and non-use. Topics covered include theoretical implications, psycho- and neurolinguistic approaches, linguistic and extralinguistic factors, L2 attrition, and heritage languages.

A pioneering study of heritage languages, from a leading scholar in this area of study world-wide.

Gender as a morphosyntactic feature is arguably “an endlessly fascinating linguistic category” (Corbett 2014: 1). One may even say it is among “the most puzzling of the grammatical categories” (Corbett 1991: 1) that has raised probing questions from various theoretical and applied perspectives. Most languages display semantic and/or formal gender systems with various degrees of opacity and complexity, and even closely related languages present distinct differences, creating difficulties for second language learners. The first three chapters of this volume present critical reviews in three different areas – gender assignment in mixed noun phrases, subtle gentle biases and the gender acquisition in child and adult heritage speakers of Spanish – while the next six chapters present new empirical evidence in the acquisition of gender by bilingual children, adult L2/L3 learners and heritage speakers of various languages such as Italian, German, Dutch or Mandarin-Italian.

In our increasingly multilingual modern world, understanding how languages beyond the first are acquired and processed at a brain level is essential to design evidence-based teaching, clinical interventions and language policy. Written by a team of world-leading experts in a wide range of disciplines within cognitive science, this Handbook provides a comprehensive overview of the study of third (and more) language acquisition and processing. It features 30 approachable chapters covering topics such as multilingual language acquisition, education, language maintenance and language loss, multilingual code-switching, ageing in the multilingual brain, and many more. Each chapter provides an accessible overview of the state of the art in its topic, while offering comprehensive access to the specialized literature, through carefully curated citations. It also serves as a methodological resource for researchers in the field, offering chapters on methods such as case studies, corpora, artificial language systems or statistical modelling of multilingual data.
