Definition of Morpheme
Morpheme is the smallest linguistic unit which has a meaning or grammatical function. Some words are not composed of other morphemes, for example, car, spider, and race. But, they are also morpheme since they cannot be broken down into smaller meaningful parts.
A morpheme may be represented by a single sound, a single syllable or more than one syllable.
Girl girl (one morpheme)
Books book + -s (two morphemes)
Underdevelopment under- + develop + -ment (three morphemes)
Undesirability un- + desir (e) + -abl (e) + -ity ( four morphemes)
A morpheme ( the minimal linguistics sign ) is thus a grammatical unit in which there is an arbitrary union of sound and a meaning that cannot be further analyzed.
