Eve V. Clark, First language acquisition. Cambridge: Cambridge University Press, 2003. Pp. xvi, 515. Hb $90.

Eve Clark's comprehensive book makes an important addition to those works already available on first language acquisition. A commendable feature is the inclusion of many non-English examples, although most are from English. In the field of language acquisition there has been an emphasis on cross-language comparisons over the past few years, as shown by the number of journal articles and chapters published, but there has not been a comprehensive single-authored book which has attempted to incorporate the recent cross-language findings. Clark's work goes a long way to filling this gap.
