Title:A case for Enriched Inputs
Authors:Ronald Sprouse
Abstract:In this paper I anlayze complex alternations which require an

intermediate representation between UR and output and therefore

appear to pose a serious problem for OT and other two-level theories

of phonology. I argue for the need for an intermediate representation

in OT and propose the Enriched Input model, which provides this

representation without creating a true three-level theory. An

intermediate representation is motivated by cases of compensatory

lengthening triggered by affixation as well as an opaque relationship

between epenthesis and deletion in Turkish, both of which require a

link between non-surfacing segments and syllable structure that is

not present in UR. The Enriched Input model provides a set of candidate

inputs of varying degrees of syllabification, all of which are required

to unify with the underlying representation. Candidate input-output

mappings are evaluated on the well-formedness of the input and output

and Faithfulness of the input-output mapping. The evaluation of

candidate input-output mappings is accomplished through use of a

tableau des tableaux of the type already proposed for Lexicon

Optimization. The paper concludes by showing how the Enriched Output

model can be applied to other types of opacity, such as the relationship

between vowel harmony, lowering, and epenthesis in Yowlumne (Yawelmani).
