K. David Harrison and Abigail Kaun
The principles of Lexicon Optimization dictate that predictable feature
values will be missing from input representations only when they exhibit
surface alternations. Patterns of vowel harmony and disharmony in Finnish
and Tuvan indicate that this is not the case.
We argue that the theory of underspecification that falls out from
Lexicon Optimization is too restrictive. We instead propose a theory of
Pattern-Responsive Lexicon Optimization (PRLO) under which a pervasive
phonological pattern may yield underspecified input representations, even
in the absence of surface alternations. Such patterns may promote the
selection of an underspecified input representation over a fully-specified
one, even when mapping the appropriate surface form to the fully-specified
alternative would involve fewer constraint violations.
