This book presents the latest developments in crosslinguistic influence (CLI) and multilingualism research. The contributors consider CLI in lexis, syntax, tense-aspect, morphology, phonology of multilingual production and link it to concepts such as redundancy, affordances, metalinguistic awareness and L2 status.
