Title:Anti-faithfulness and Subtractive Morphology
Authors:Graham Horwood
Abstract:In the Muskogean language Koasati (Kimball 1991), pluralization in
indicative verbs may be shown allomorphically by truncation of a
root-final rhyme or consonant. This phenomenon and others like it fall
under the heading of subtractive morphology: truncation of a prosodic
category from a morphological one. The present work will show that
subtractive morphological operations of the type found in Koasati are best
accounted for under the Optimality-theoretic Transderivational
Anti-faithfulness model of Alderete (2000). The essential argument is
that high-ranking anti-MAX constraints are operative on the
OO-correspondence relation of the singular/plural paradigm, forcing
truncation of at least one segment in the derived word in a manner
restricted by more general phonological constraints on the grammar.
Examination of anti-faithfulness constraint interactions in the grammars
of Koasati, Tohono O\'odham, and Lardil will illustrate a more general
morph-phonological framework under which subtractive morphological
operations may be analyzed without reference to the syllable or rhyme
template which previous analyses of subtraction have relied upon. This is
a result desirably in accord with the goals of Prosodic Morphology set out
in McCarthy and Prince (1993a).
