A morpheme is the smallest meaningful unit of language. It may be a word or a part of a word, such as a prefix or a suffix. For example, in the word “unhappy,” “un-” is a morpheme that indicates negation, and “happy” is a morpheme that conveys the base meaning of the word.

Unhappiness consists of three morphemes: un- (prefix), happy (root), and -ness (suffix).

A morph is a form that represents a specific morpheme. It can be a word or a part of a word. For example, the word “cats” consists of two morphs: “cat” (the base form) and “-s” (the morph indicating pluralization).

An allomorph is a variant form of a morpheme that has a similar meaning but is pronounced or written differently in different contexts. Allomorphs typically occur due to sound changes or phonological rules within a language. For example, the plural morpheme “-s” can be pronounced as /s/ (as in “cats”), /z/ (as in “dogs”), or /ɪz/ (as in “watches”), depending on the preceding sounds.

A morpheme is the smallest meaningful unit, while a morph is a form that represents a specific morpheme. Allomorphs, on the other hand, are multiple variant forms of a single morpheme. Morphemes and morphs can be stand-alone words, such as “book” or “un-“, while allomorphs are context-dependent and can only occur as part of a larger word.

A morpheme carries meaning, whether it’s a word or a part of a word. A morph represents a specific morpheme and helps express its meaning. Allomorphs, however, do not inherently carry meaning by themselves but contribute to the overall meaning of a word.

Morphemes and morphs have consistent pronunciations. For example, the morpheme “cat” will always be pronounced as /kæt/, and the morph “un-” will always be pronounced as /ʌn/. Allomorphs, on the other hand, can have different pronunciations depending on the surrounding sounds, as seen with the various pronunciations of the plural morpheme “-s” mentioned earlier.
