Introduction: Linguistic universals and language change

Abstract

Certain grammatical patterns are found again and again in the languages of the world. Some of these patterns recur so frequently that they are given the label “universal”. Explaining the source of such patterns is clearly an important goal of linguistics, but how to go about doing this is not obvious. Problems range from the terminological (what sort of patterns should we consider universal?) to the methodological (what kind of explanation will we accept as sufficient?) to the theoretical (what role does a universal grammar have in shaping recurrent patterns? what role do functional considerations play?). How one answers one of these questions will affect how one answers the others. Can probabilistic generalizations be considered universals? If so, then we need explanations predicting probabilistic patterns. Are we looking for proximate explanations (for example, “language A shows pattern X because it inherited it from its parent language”) or ultimate ones (for example, “language A shows pattern X because only this pattern is permitted by Universal Grammar”)? Will we assume there is no such thing as Universal Grammar? Then, of course, we cannot appeal to it for any sort of explanation. Will we assume there is such a thing? Then, what is its precise structure?
