This anthology draws together leading linguists, logicians, and computer scientists working on Head-Driven Phrase Structure Grammar and Construction Grammar. Covering a wide array of linguistic topics and languages, the papers in this book document the singular ability of lexicalist theories of grammar to provide analyses which combine the advantages of explanatoriness, analytic precision, and thorough empirical data coverage. Topics that are discussed include: argument structure, idiomatic constructions, case and agreement, anaphora and ellipsis, syntactic locality and nonlocality, quantification, word structure, issues in processing and formalization, and unbounded dependencies.
