Morph, Allomorph, Morpheme. Linguistics 323. Morphology. A morph is a phonological string (of phonemes) that cannot be broken down into smaller constituents that have a lexicogrammatical function. In some sense it corresponds to a word-form. An allomorph is a morph that has a unique set of grammatical or lexical features. All allomorphs with the same set of features forms a morpheme. A morpheme, then, is a set of allomorphs that have the same set of features.
