Book excerpt: This volume contains new research on the lexicon and its relation to other aspects of linguistics. These essays put forth empirical arguments to claim that specific theoretical assumptions concerning the lexicon play a crucial role in resolving problems pertaining to other components of grammar. Topics include: syntactic/semantic interface in the areas of aspect, argument structure, and thematic roles; lexicon-based accounts of quirky case, anaphora, and control; the boundary between the lexicon and syntax in the domains of sentence comprehension and nominal compounding; and the possibility of extending the concept of blocking beyond the traditional lexicon. Ivan Sag is a professor of linguistics at Stanford University. Anna Szabolcsi is an associate professor of linglustics at UCLA.
