Competitors and Alternants in Linguistic Morphology

Complementary distribution is a consequence of a general principle of evolutionary biology, competitive exclusion, which further provides a uniform account of both allomorphic variation and the rivalry between affixes in terms of competition for distributional resources. The distribution of inflectional competitors is a type of spatial partitioning, restricted by the morphosyntactic system of a language, while derivational rivals benefit from having to name externally driven concepts. The English suffixes -ce, -cy, and -ntial are analyzed in detail as examples of competition for distribution.
