Written for students encountering the topic for the first time, this is a clear and practical introduction to second language acquisition (SLA). It explains in non-technical language how a second language is acquired; what the second language learner needs to know; and why some learners are more successful than others. The textbook introduces in a step-by-step fashion a range of fundamental concepts – such as SLA in adults and children, in formal and informal learning contexts, and in diverse socio-cultural settings – and takes an interdisciplinary approach, encouraging students to consider SLA from linguistic, psychological and social perspectives. Each chapter contains a list of key terms, a summary, and a range of graded exercises suitable for self-testing or class discussion. Providing a solid foundation in SLA, this book is set to become the leading introduction to the field for students of linguistics, psychology, and education, and trainee language teachers.

"When i received this book, I was five weeks into my introduction to SLA graduate seminar. I found Sayville-Troike's text helpful in organizing some of the remaining content of my course. By structuring an SLA course around the main questions the field investigates, Saville-Troke focuses students' attention on the important issues that illuminate the study of SLA. The adaptable nature of the book also makes it ideal for courses that include both undergraduate and graduating students, and for courses that have both students who intend to continue taking courses in SLA, and those who do not. Saville-Troike's text is a timely and welcome addition to the profession." - Wynne Wong, Ohio State University
