Abstract

This chapter is concerned with Noam Chomsky's influence on historical linguistics, one might also ask about the influence of historical linguistics on Chomskyan thought. It outlines the tension between Chomskyan generative grammar and historical linguistics and argues how both have been beneficial to each other. Generative grammar and historical linguistics can benefit from each other's insights. The chapter explains how there is a great deal of influence of Chomskyan, generative linguistics on historical linguistics, in particular syntax, and also shows how Third Factor Principles shape language change. Chomsky's current focus on labeling as a Third Factor effect necessitated by the interfaces and unconnected to Merge makes it possible to see syntactic change in another way, namely as a resolution to labeling problems. Apart from labeling, there are other Third Factor Principles, such as the one to avoid indeterminacy in a derivation.
