The idea that functional load offers a tool of potentially great explanatory power in diachronic linguistics is shared by a number of contemporary linguists, particularly those influenced at first or second hand by Prague. It is the purpose of the present paper to investigate the hypothesis that functional load plays a significant role in sound change. I will attempt to demonstrate that functional load, if it is a factor in sound change at all, is one of the least important of those we know anything about, and that it is best disregarded in discussions centering on the cause and direction of phonological change.
