This article is about a lingustic term. See Pseudomorph for another meaning of the word.
In linguistics an allomorph is a variant form of a morpheme. The meaning remains the same, while the sound can vary.
For example, in the English language the past tense morpheme is -ed. It occurs in several allomorphs depending on its phonological environment, assimilating voicing of the previous segment or inserting a schwa when following an alveolar stop:
- as /əd/ in 'hunted' or 'banded',
- as /d/ in 'buzzed',
- as /t/ in 'fished'
| Singular | Plural | |
|---|---|---|
| Nominative | ||
| Genitive | ||
| Instrumental | ||
| Locative |
The nominative /vaːk/ is the basic form of the morpheme and, because of Pre-Indic palatalazation of velars and the merging of /e/ and /o/ into /a/ (making the alternation unpredictable on phonetic grounds), morphophonemic variation has occurred that isn’t directly related to phonological processes.
