This text provides a comprehensive introduction to current thinking on language acquisition. Following an introductory chapter that discusses the foundations of linguistic inquiry, the book covers the acquisition of specific aspects of language from birth to about age 6. Topics include the language abilities of newborns, the acquisition of phonological properties of language, the lexicon, syntax, pronoun and sentence interpretation, control structures, specific language impairments, and the relationship between language and other cognitive functions. At the conclusion of each chapter are a summary of the material covered, a list of keywords, study questions, and exercises. The book, which adopts the perspective of Chomskyan Universal Generative Grammar throughout, assumes a familiarity with basic concepts of linguistic theory.Guasti, Maria Teresa is the author of 'Language Acquistion The Growth of Grammar', published 2004 under ISBN 9780262572200 and ISBN 0262572206.
