Abstract

This chapter examines Chomsky's influence on the modeling of linguistic variation, focusing specifically on the notion of parameter. It begins by examining the different conceptualizations of “parameter” in Chomsky's work, from the Government and Binding era, through early Minimalism to more recent approaches which locate variation in phonological form. The idea that grammatical variation should be modeled by abstract parameters is arguably one of Chomsky's most important contributions to linguistic theory, and one which has had significant influence. Two domains of variation (word order and argument expression) are used as case studies to illustrate how Chomsky's ideas have given rise to different kinds of parametric models. Finally, the chapter discusses some of the potential objections to the concept of parameters before concluding.
