ALLOMORPH
allomorph is a variant form of a morpheme, that is, when a unit of meaning varies in sound without changing meaning.
An allomorph is
an alternate pronunciation of a phonological form of a morpheme in a particular
linguistic environment.
For example the “s”
morpheme in english which indicates plurality or third person singular present
tense has three allomorphs :
Cats / kaets / Dogs
/ dogz / Horses / ho:sez /
Likes / laiks / rubs / rabz / hisses / hisez /
Thus,
orthographically the same “s” manifestation holds, but phonologically, there
are three variants, /s/z/ and /ez/ making up the three allomorphs of the
morphemes.
So, The allomorphs
of English plural are: /әz/,
/s/, /z/
1.
[әz] occurs on nouns ending in s, z, š, z, č, j. (sibilants)
2.
[s] occurs following all other voiceless sounds
3.
[z] occurs following all other voiced sounds
Allomorph
for english past tense :
Wish / wished /
Talk / talked /
Kiss / kissed /
ADD [t] if following voiceless sound
Grab / grabbed /
Love / Loved /
ADD [d]
Want/ wanted
wait/ waited
