[T]he book will be welcome to all who are looking for empirical testing grounds for their categorization theories. Many of the gradual (and not so gradual) linguistic distinctions underlying the categories presented here will hopefully lay one simplistic assumption to rest: A handful of 'word classes' handed down from antiquity will not help us in defining satisfactory linguistic theories. Given the lack of attention this important fact often recieves, this is a very welcome result indeed.

Given that word classes have been treated numerous times in modern linguistics, this volume might at first sight appear to be an unremarkable and perhaps unnecessary addition to the pile. However, such an assumption would be terribly misguided. Much of the research reported in the volume is groundbreaking and provides new insights into the increasingly complex world of word classes. Several contributions in the book cover aspects of word classes that have either not been addressed before or which have not received much attention. In this respect, the book as a whole constitutes an important contribution to the study of word classes.
