COGNITIVE GRAMMAR. John R. Taylor. Oxford: Oxford University Press, 2002. Pp. xii + 621. $29.95 paper.

This volume is not aimed at SLA researchers but is a book that SLA researchers interested in usage- and frequency-based models will find valuable. Taylor provides a lucid, comprehensive account of Langacker's theory of Cognitive Grammar (CG) and along the way also offers a thoughtful introduction to Cognitive Linguistics (CL). Of the many approaches within CL, CG has a notably wide scope and high degree of internal consistency and, thus, is particularly worthy of SLA researchers' attention. CG's central premise is that language is inherently symbolic and that linguistic expressions symbolize—or represent—conceptualization. In the original, Langacker's writing is technical and detailed, with many unfamiliar formal conventions; Taylor provides the uninitiated with a thorough, clear introduction to this significant, innovative work. SLA researchers will find it a valuable resource that provides many access points into CG and CL.
