On the formal expression of natural rules in phonology

Abstract

While the notion of naturalness or plausibility has been a tacit guiding principle for past generations of phonologists, the effort to accord the notion of naturalness a theoretical status and to incorporate this notion into the descriptive formalism of a linguistic theory was a major innovation by the generative school. In accordance with what we may refer to as the ‘formalness condition’, the generativist requires that the substantive naturalness of a phonological process be explicitly recognizable in the very formalism used to state the process. The lively interest in and the on-going search for a ‘natural’ phonology is very much in evidence, witness, e.g., the titles of papers presented at the 1971 Annual Meeting of the Linguistic Society of America.
