What are allomorphs?
[NU-‘14,‘18]
In linguistics, allomorphs are variants of a
morpheme that differ in pronunciation but are semantically identical.
Allomorphs are used in linguistics to explain the comprehension of variations
in sound for a specific morpheme.
English has several morphemes that vary in sound but not in
meaning. For example, in English, a past tense morpheme is ‘ed’. It occurs in
several allomorphs depending on its phonological environment, assimilating,
voicing of the previous segment.
However, allomorphs vary in shape or pronunciation according
to their condition of use but not as to meaning.
Explain the difference between free
morphemes and bound morphemes. [NU-‘15,‘17]
Morphemes can be divided into two major classes. These are:
free morphemes and bound morphemes.
Free morphemes: The morphemes that can function independently, are called
free morphemes. For example: man, boy, girl, cow, mango, cruelty, beauty, is,
and, but and so on. Free morphemes are of two types. These are:
1. Lexical free
morphemes,
2. Grammatical free morphemes.
Bound
morphemes: There are some morphemes that cannot function alone and are
added to root words. This type of morpheme is called bound morphemes. For
example: -less, -ness, pre- , -ment, un-, im- and so on. Bound morphemes are of
two types. These are:
1. Bound roots,
2. Affixes.
