In recognition of the tremendous variation across children and language, the fifth edition of this readable book devotes much more space to individual developmental differences and cultural differences. Discussion of other cultures has been included wherever possible. In addition, the sections on bidialectalism and bilingualism have been expanded to reflect more accurately the realities of everyday life in the United States. Developed within a chronological framework, every aspect of syntax, morphology, semantics, phonology, and pragmatics is examined. For anyone interested in language development.
