Allomorph is a linguistics term for a variant form of morpheme.

In some cases a morpheme has more than one allomorph.

Concept of allomorph occurs when a unit of meaning can vary in sound (phonologically), but the meaning is remain the same.

It is used in linguistics to explain the comprehension of variation in sound

for a specific morpheme.

In some cases a morpheme has more than one allomorph.

This happens when the same meaning unit like [past] for past

tense or [pl] for plural has more than one sound form

Past: one feature [past] kick / kick-ed leave / lef-t hit / hit-Ø

Different allomorphs of a morpheme are part of the same morpheme, but are found in particular contexts.

The same is true of the different allomorphs of a morpheme

Which allomorph of a morpheme is found depends on its context;

Example: consider [pl] for English plural. It normally has the pronunciation –s (i.e. /z/),

but

moose / moose- Ø

ox / ox-en

box/*box-en/box-es

So, the special allomorphs depend on the noun

Regular and irregular allomorph

In the examples above, the different allomorphs have a distinct status. One of them is regular.

This is the default form that appears when speakers are using new words: (one blork,

two blorks)For another allomorphs, speakers have to

memorize the fact that the allomorph is what it is

Example: It cannot be predicted from other facts that the plural of ox is ox-en

Demonstration: The regular plural is /z/; consider one box, two box-es.

Default cases like the /z/ plural are called regular.

Allomorphs that have to be memorized are called

irregular.Irregular allomorphs block regular allomorphs from

occurring (ox-en, not *ox-es or *ox-en-s).

Two types of Allomorph

The Plural morpheme in English has different sound-forms: dog-s/cat-s/church-

esThese are predictable,

based on the phonological context

In the case of Past Tense allomorphy, it is not predictable from the phonology which affix

appears

We can find verbs with the same (or similar) sound form, but with

different allomorphs: break/broke, not stake/*stoke

In English, the negative prefix ‘in’ has several allomorph. For examples:1.in-capable2.il-logical3.im-probable4.ir-relevent
