- This paper addresses how we should deal with underlying representation (UR) in Optimality Theory (OT ), focusing in particular on the proper method of Lexicon Optimization (LO), a mechanism in OT that determines a 'real' input among various possible inputs. After closely examining previous proposals, I conclude that Kager's (1999) model of LO is most promising, only if it is controlled by a meta- principle, Input- Output Isomorphy, that guarantees a UR to be identical to its surface form in the cases where underlying contrasts are expressed at surface level. I demonstrate that LO performed in this way provides a good account of UR for allomorphy cases without posing any problem to Richness of the Base, one of the fundamental concepts in OT.
