(Aka Sound Pattern of English)
A 1968 work on phonology by Noam Chomsky and Morris Halle that presented phonology as a linguistic subsystem that was separate from other parts of the grammar.
According to Chomsky and Halle, phonology works by transforming an underlying phonemic sequence according to rules, and produces as its output the phonetic form that is uttered by a speaker.
1. The theory fits with the rest of Chomsky's early theories of language in the sense that it is transformational.
