This article aims to offer some unified analysis of a couple of irregular stems in Korean. The l-gemination attested in /lɨ/-irregular stems turns out to be compensatory in nature, and so the phenomenon comes under the purview of moraic theory. The /t/-irregular stems are basically shown to be conditioned in the lexicon. But it is argued that their allomorphic choice becomes phonologically natural once the stem is assumed to carry two underlying allomorphic variants in the lexicon. Those two allomorphs are closely related in that they have the feature value of [voice] unspecified in the input. The value will be filled in with the help of a universal constraint in charge of agreement. Then, what appears to be irregular in the allomorphy of /t/-irregular stems in question is not a phonological irregularity at all, but rather results from a different match between morphemes that under more normal circumstances would not be expected to happen. On the other hand, emergence of nondistinctive [d] and [ɹ] in the conjugation of regular as well as irregular stems should not be something that happens within phonology. It must be an allophonic process taking place in the environment of intervocalic position, so it stands reason to treat it in terms of phonetic implementation.
