Modeling sublexical contrast maintenance as an emergent effect of lexical category competition

Andy Wedel

The transmission of information requires a contrastive code. Standard linguistic models locate the building blocks of contrast in a set of atomic sound categories which in combination subserve contrast between higher order sound-meaning categories, such as words. The mechanism of contrast maintenance between these atomic sound categories through the course of language change has been unclear, particularly given that contrast has its function at higher, sound-meaning category levels. However, given the growing body of evidence indicating that variation is recorded at multiple levels of organization. I argue here that contrast maintenance may arise instead at the sound-meaning level through usage, producing an indirect, non-teleological mechanism for selection for contrast at the level of sound categories. As an example, I show that variant trading between categories competing for percepts results in categorial contrast maintenance, and that within simulations, sound category contrast can arise epiphenomenally through word category competition.
