The main focus of this timely volume is phonological acquisition or the process of mastering a second language facilitated by guidance and direction. This thematic volume of recent research in the field comes at a time when phonology - always one of the liveliest areas of theoretical linguistic inquiry - is starting to enjoy a much-deserved resurgence of interest and writings within the realm of second-language acquisition. The scope of coverage in this volume includes phonological acquisition as well as requirements of language education where phonology refers not only to linguistically relevant dimensions of speech but related concerns of psychology as well.
