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

Heritage languages are minority languages learned in a bilingual environment. These include immigrant languages, aboriginal or indigenous languages and historical minority languages. In the last two decades, heritage languages have become central to many areas of linguistic research, from bilingual language acquisition, education and language policies, to theoretical linguistics. Bringing together contributions from a team of internationally renowned experts, this Handbook provides a state-of-the-art overview of this emerging area of study from a number of different perspectives, ranging from theoretical linguistics to language education and pedagogy. Presenting comprehensive data on heritage languages from around the world, it covers issues ranging from individual aspects of heritage language knowledge to broader societal, educational, and policy concerns in local, global and international contexts. Surveying the most current issues and trends in this exciting field, it is essential reading for graduate students and researchers, as well as language practitioners and other language professionals.

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

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.

Age effects have played a particularly prominent role in some theoretical perspectives on second language acquisition. This book takes an entirely new perspective on this issue by re-examining these theories in light of the existence of apparently similar non-native outcomes in adult heritage speakers who, unlike adult second language learners, acquired two or more languages in childhood. Despite having been exposed to their family language early in life, many of these speakers never fully acquire, or later lose, aspects of their first language sometime in childhood. The book examines the structural characteristics of "incomplete" grammatical states and highlights how age of acquisition is related to the type of linguistic knowledge and behavior that emerges in L1 and L2 acquisition under different environmental circumstances. By underscoring age of acquisition as a unifying factor in the study of L2 acquisition and L1 attrition, it is claimed that just as there are age effects in L2 acquisition, there are also age effects, or even perhaps a critical period, in L1 attrition. The book covers adult L2 acquisition, attrition in adults and in children, and includes a comparison of adult heritage language speakers and second language learners.

Heritage languages, such as the Turkish varieties spoken in Berlin or the Spanish used in Los Angeles, are non-dominant languages, often with little prestige. Their speakers also speak the dominant language of the country they live in. Often heritage languages undergo changes due to their special status. They have received a lot of scholarly attention and provide a link between academic concerns and educational issues. This book takes a language contact perspective: we consider heritage languages from the perspective of their history, their structural properties, and their interaction with other surrounding languages.

This book provides a pioneering introduction to heritage languages and their speakers, written by one of the founders of this new field. Using examples from a wide range of languages, it covers all the main components of grammar, including phonetics and phonology, morphology and morphosyntax, semantics and pragmatics, and shows easy familiarity with approaches ranging from formal grammar to typology, from sociolinguistics to child language acquisition and other relevant aspects of psycholinguistics. The book offers analysis of resilient and vulnerable domains in heritage languages, with a special emphasis on recurrent structural properties that occur across multiple heritage languages. It is explicit about instances where, based on our current knowledge, we are unable to reach a clear decision on a particular claim or analytical point, and therefore provides a much-needed resource for future research.
