Abstract

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book deals with the nature of hierarchical relations, in particular the computational procedure needed to generate such relations. It discusses the importance of linguistic diversity in Chomsky's work. Chomsky's own work has mostly focused on synchronic grammatical analyses. The book describes ways in which work on second language acquisition has embraced theoretical developments in syntax, and how it has sometimes informed those developments as well. It also discusses different declarative frameworks, shows in detail how they are compatible with Chomsky's early work, and provides examples of grammatical analyses within such frameworks. The book explains the differences between Chomsky's linguistics and what can broadly be labeled “usage‐based linguistics.” It explores how Chomsky's work has influenced research on one area of linguistic performance, namely sentence processing or “parsing.”
