Phon-something: a clarification

This is an attempt to set phonology and its neighbours in and out of the gra mmar in a consistent theory of mind. A series of definitions of modes of sound perception (and production) is offered with as little co mmitment as possible to any particular set of phonological tenets. The idea is to make sense of the modi operandi of phonology and its interfacing with other levels of representation, giving due regard to considerations of learnability, and (even) of evolution.
