This book investigates the critical role of phonological acquisition in the broader framework of second language learnability. It examines how learners acquire the sound systems of new languages, focusing on the interplay between innate linguistic capacities and external linguistic input. The work syntheses existing research and presents new theoretical perspectives on the challenges and mechanisms involved in mastering L2 phonology, considering factors such as age, first language influence, and the nature of the target language.

This text is recognized as a significant contribution to the field of Second Language Acquisition, particularly within the sub-discipline of L2 phonology. It is likely to be regarded as a dense, academic work suitable for advanced students and researchers in linguistics. The book's focus on theoretical frameworks and empirical evidence suggests it aims to advance scholarly understanding of language learnability.
