This is a very important work and represents a major advance in the understanding of the dependence of syntactic description on an explicit semantic analysis. This work is especially valuable because the role of semantics, particularly the lexical semantics of verbs, has become increasingly central in current formal theories of syntax, and few semantic theories are as well worked out as that presented here. Syntactic theorists would be well advised to study this book carefully before they glibly invoke vague ( and potentially circular) semantic explanations for syntactic problems.

The entire book is written in a maximally clear and simple language. It invites the reader, in a friendly manner, into the creative laboratory, where there is being accomplished a wondrous process of reaching the complex through the simple. At the same time, it is a simplicity deeply thought through; behind it lies a professionalism of the highest order and many years of systematic thinking about the nature of human language.

Irrespective of theoretical orientation, one can only be impressed by the scope of the empirical investigation as well as the depth and insight of the resulting semantic descriptions. The theoretical tenets of Anna Wierzbicka's Natural Semantic Metalanguage approach are provocative and highly controversial. They focus attention on fundamental issues and force us to rethink the nature of linguistic meaning and psychologically plausible semantic descriptions. Linguists of all persuasions can profit from examining the analyses presented in this work, the theoretical proposals made, and their possible ramifications.
