ALLOMORPHS:

VARIATIONS OF MORPHEMES

DEFINITION:

An allomorph is ‘any of the different forms of a

morpheme’.[Richards, Platt & Weber, 1987: 9]

EXAMPLE: long, length

NOTE: a morpheme may have more than

one phonemic form.

SELECTION OF ALLOMORPHS:

•The past-tense ending , the morpheme {-D pt}, has

three phonemic forms.

•The choice depends on the preceding sound.

NOTE: These three phonemic forms of {-Dpt} are not

interchangeable. They are positional variants. They

are allomorphs belong to the same morpheme.

Page 7: Allomorphs - Dr. Shadia Yousef Banjar

•It must be emphasized that many morphemes in English have only one phonemic form, that is, one allomorph – for example, the morpheme {boy} and {-hood} each has one allomorph - /bŦŦŦŦy/ and /-hUd/ - as in boyhood.

Dr. Shadia Yousef Banjar7

allomorph - /bŦŦŦŦy/ and /-hUd/ - as in boyhood.•It is really not the morpheme but the allomorph that is free or bound.•For example the morpheme {louse} has two allomorphs: the free allomorph /laws/ as in the singular noun louse , and the bound allomorph /lawz-/ as in the adjective lousy.

TYPES OF ALLOMORPHS

Dr. Shadia Yousef Banjar8

Page 9: Allomorphs - Dr. Shadia Yousef Banjar

1. ADDITIVE ALLOMORPHS:

To signify some difference in meaning, something is added to a word. For example, the

past tense form of most English verbs is formed by adding the suffix –ed which can be pronounced as either /–t/, /–d/ or /–ƽƽƽƽd/:

ask + –ed = /a:sk/ + /–t/, liv(e) + –ed =/lΙv/ + /–d/, need + –ed =/ni:d/ + /–ƽƽƽƽd/.

2. REPLACIVE ALLOMORPHS:

To signify some difference in meaning, a sound is used to replace another sound in a

word. For example, the /Ι/ in drink is replaced by the /æ/ in drank to signal the simple

past. This is symbolized as follows:

/drænk/ = /drΙnk/ + / Ι > æ /.

3. SUPPLETIVE ALLOMORPHS:

To signify some difference in meaning, there is a complete change in the shape of a word.

Dr. Shadia Yousef Banjar9

To signify some difference in meaning, there is a complete change in the shape of a word.

For example:

� go + the suppletive allomorph of {–D pt} = went;

� be + the suppletive allomorph of {–S 3d} = is;

� bad + the suppletive allomorph of {–ER cp} = worse;

� good + the suppletive allomorph of {–EST sp} = best.

4. THE ZERO ALLOMORPH:

There is no change in the shape of a word though some difference in meaning is

identified. For example, the past tense form of hurt is formed by adding the zero

allomorph of {–D pt} to this word.

A schematic representation of the lexicon as the irregular allomorphs are

stored as distinct lexical entries, while the regular past tense form is

derived by combining the stored stem and the stored past tense

morpheme according to the regular rule. (Linnaea C. Stockall, 1999).

allomorphs of the same morpheme.
