How Second Languages are Learned

'This book provides a very clear and accessible introduction to second language acquisition viewed from a linguistic perspective. Readers will come away with an excellent grasp of the central issues that have dominated the field, including the task facing learners and the linguistic properties that must be acquired. The effects of age, input, and the mother tongue are carefully assessed, as well as theories and debates about the nature of second language acquisition. Highly recommended as an introductory textbook for non-specialists and would-be specialists alike.' Lydia White, McGill University, Montreal
