Automatic Alternations in Non-Transformational Phonology

Abstract

Automatic alternations, those traditionally understood to be required by phonetic structure, have not been a part of transformational generative phonologies, where alternations are described by feature-changing P-rules. ‘Conspiracies’, the justification of two or more alternation P-rules by some requirement of phonetic structure, have also gone unexpressed. Phonetic structure is properly expressed by non-transformational, non-directional neutralization rules, of which alternation P-rules are partial repetitions. Automatic alternations can be considered alternations of completely with incompletely specified phonemes, resulting from a neutralization of features. If the features subject to neutralization are so marked in lexical entries, this effectively represents the automatic allomorphs, permitting the non-directional phonetic-structure rules to accomplish automatic alternations by selecting the correct alternants in environments of neutralization. (An illustration of this is an automatic-alternation conspiracy in Kambata, a language of Ethiopia—resulting from historical assimilations, vowel deletion, and metathesis.) The result is a non-transformational phonology consistent with the general tendency of leveling—one in which automatic alternations, conspiracies, and all non-controversial generalizations are expressed in a grammar which prohibits ordered rules and requires that all rules and representations be surface-true.
