Morphemes are the smallest units that carry meaning. A morpheme can be a free morpheme, which can stand alone as a word, or a bound morpheme, which must be attached to other morphemes. A morph is the actual form used to realize a morpheme. For example, the word "cats" has two morphs, /kæt/ and /s/. An allomorph is an alternative pronunciation of the same morpheme. For example, the plural morpheme /s/ has allomorphs like /s/ in "books" and /z/ in "dogs".

1. Morph Morpheme &
Allomorph

2. A. Morpheme
1. Definition ofMorpheme
According to Blau (2010 : 156), Morpheme is the
smallest element that carry a sense or meaning. which
means every single word which have a meaning either
it is need to be insterted to another word or it can
stand by it self, is called a morpheme.
Ex: Unthinkable = 'un-' 'think' and '-able‘
Ex: Books = Book and s.

3. 2. Types ofMorpheme
In his book entitled The Study of Language Forth
Edition (2010 : 68) Yule stated, morpheme has been
divided into 2 sort of it, they are:
a. Free Morpheme
b. Bound Morpheme
Note: See chapter one for detailed description about morpheme
types.

4. B. Morph
1- Definition of Morph
Francis (1958 : 170) stated, morph is a meaningful group
of phones which can’t be subdivided into smaller
meaningful units.
On the other handYule (2010 : 71)stated, morph is actual
form used to realize a morpheme.

5. For Example :
The word cats has two morphs /kæt / and –s /s/
The word buses has two morphs /bʌs / and –es /s/
So we can conclude the meaning of morph
regarding to the explanation of Yule and Francis with
the example above. Morph is a general term for all
morphemes.

6. C. Allomorph
Definition ofAllomorph
McCarthy (2002 : 22) stated, a morpheme that have two
or more different pronunciations called an allomorph.
It is supported by Lieber (2009 : 158) who said,
Allomorph is phonologically distinct variant of the same
morpheme. Which we can say an allomorph is the
different pronunciation of the same morpheme.

7. Examples of Allomorph
Example-1
The plural morphemes in English, usually written as {s}, has at least 3 allomorphs:
-s as in books /buks/
-z as in dogs /dogz/
-iz as in boxes /boksiz/
Example-2
The past form morpheme {ed} usually has also three allomorphs:
-d as in ‘played’ /pled/
-t as in ‘fished’ / fist/
-id as in ‘banded’ /bendid/

8. Difference between Morpheme,
Morph and Allomorph
A. Morpheme is the smallest unit that carries a meaning.
B. Morph is the actual form of morpheme. The real form of
morpheme that makes a deal in building the structure of
word or the word itself. Or we can say it as the general
termto say morpheme
C. Allomorph is the variant of pronunciation of a morpheme.
