Third language acquisition is a common phenomenon, which presents some specific characteristics as compared to second language acquisition. This volume adopts a psycholinguistic approach in the study of cross-linguistic influence in third language acquisition and focuses on the role of previously acquired languages and the conditions that determine their influence.

This book deals with the phenomenon of third language (L3) acquisition. As a research field, L3 acquisition is established as a branch of multilingualism that is concerned with how multilinguals learn additional languages and the role that their multilingual background plays in the process of language learning. The volume points out some current directions in this particular research area with a number of studies that reveal the complexity of multilingual language learning and its typical variation and dynamics. The eight studies gathered in the book represent a wide range of theoretical positions and offer empirical evidence from learners belonging to different age groups, and with varying levels of proficiency in the target language, as well as in other non-native languages belonging to the learner’s repertoire. Diverse linguistic phenomena and language combinations are viewed from a perspective where all previously acquired languages have a potential role to play in the process of learning a new language. In the six empirical studies, contexts of language learning in school or at university level constitute the main outlet for data collection. These studies involve several language backgrounds and language combinations and focus on various linguistic features. The specific target languages in the empirical studies are English, French and Italian. The volume also includes two theoretical chapters. The first one conceptualizes and describes the different types of multilingual language learning investigated in the volume: i) third or additional language learning by learners who are bilinguals from an early age, and ii) third or additional language learning by people who have previous experience of one or more non-native languages learned after the critical period. In particular, issues related to the roles played by age and proficiency in multilingual acquisition are discussed. The other theoretical chapter conceptualizes the grammatical category of aspect, reviewing previous studies on second and third language acquisition of aspect. Different models for L3 learning and their relevance and implications for representations of aspect and for potential differences in the processing of second and third language acquisition are also examined in this chapter. As a whole, the book presents current research into third or additional language learning by young learners or adults, considering some of the most important factors for the complex process of multilingual language learning: the age of onset of the additional language and that of previously acquired languages, social and affective factors, instruction, language proficiency and literacy, the typology of the background languages and the role they play in shaping syntax, lexicon, and other components of a L3. The idea for this book emanates from the symposium Multilingualism, language proficiency and age, organized by Camilla Bardel and Laura Sánchez at Stockholm University, Department of Language Education, in December 2016.

This book explores crosslinguistic influence in third language acquisition, drawing insights from a study of young bilingual secondary school students in Germany to unpack the importance of different variables in the acquisition and use of English as an additional language. Lorenz draws on data from a learner corpus of written and spoken picture descriptions toward analyzing sources of crosslinguistic influence in L3 acquisition in bilingual heritage speakers with unbalanced proficiency in heritage versus majority languages as compared with their monolingual German peers. This unique approach allows for a clearer understanding of the extent of influence of access to heritage languages, the impact of being a "balanced" vs "unbalanced" bilingual speaker, and the importance of extra-linguistic variables, such as age, gender, socio-economic status, and type of school. The final two chapters highlight practical considerations for the English language classroom and the implications of the study for future directions for research on third language acquisition. With its detailed overview of L2 and L3 acquisition and contribution toward ongoing debates on the advantages of being bilingual and multilingual, this book will be of interest to students and scholars in applied linguistics, foreign language acquisition, foreign language teaching, and learner corpus research.

This book presents the latest research in various areas of cross-linguistic influence (CLI), providing educators with insights into how previously learned languages influence the learning of an additional language at different levels, such as phonetics/phonology, morphosyntax, vocabulary, pragmatics, writing style and learning context. While the majority of the chapters have English as the target language, one investigates the acquisition of French. The L1s of the learners include Arabic, Basque, Catalan, Chinese, Czech, Danish, Finnish, Galician, Georgian, German, Norwegian, Polish, Russian, Spanish and Swedish. Each chapter ends with a reflection on possible pedagogical implications of the findings and offers recommendations on how to make the most of cross-linguistic influence in the classroom.

Third or Additional Language Acquisition examines research on the acquisition of languages beyond the L2 within four main areas of inquiry: crosslinguistic influence, multilingual speech production models, the multilingual lexicon and the impact of bi/mul

This book presents the latest developments in crosslinguistic influence (CLI) and multilingualism research. The contributors, both veteran researchers and relative newcomers to the field, situate their research in current debates in terms of theory and data analysis and they present it in an accessible way. The chapters investigate how and when native and non-native language knowledge is used in language production. They focus on lexis, syntax, tense-aspect, phonology of multilingual production and link it to a range of concepts such as redundancy, affordances, metalinguistic awareness and L2 status. The empirical data have been collected from participants with a wide combination of languages: besides English, German, French and Spanish, there is Finnish, Swedish, Polish, Chinese and Catalan.
