|Abstract:||Turbid Output Representations and the Unity of Opacity
Johns Hopkins University
OT has had difficulty accounting for opacity effects (Kiparsky, 1971),
which involve the violation of faithfulness unmotivated by surface
structual harmony. OT researchers have proposed that these
faithfulness violations can be motivated by relating the candidate
output to outputs of morphologically related forms (Benua, 1997) or
failed candidates (McCarthy, 1998).
This paper outlines an alternative approach: enlarging the space
of phonological representations so that outputs may contain
covert/'Turbid' structure. The proposal is illustrated through an
examination of compensatory lengthening in Luganda and
overapplication of fricative assimilation in German. We also examine
contrasts between Turbidity and other OT approaches to opacity.
