<Li> "Unbreakable" comprises three morphemes: un - (a bound morpheme signifying "not"), - break - (the root, a free morpheme), and - able (a free morpheme signifying "can be done"). </Li> <Li> Allomorphs of the plural morpheme for regular nouns: / s / (e.g. in cats / kæts /), / ɪz, əz / (e.g. in dishes / dɪʃɪz /), and / z / (e.g. in dogs / dɒɡz /). </Li> <P> A morpheme is the smallest grammatical unit in a language . In other words, it is the smallest meaningful unit of a language . The linguistics field of study dedicated to morphemes is called morphology . A morpheme is not identical to a word, and the principal difference between the two is that a morpheme may or may not stand alone, whereas a word, by definition, is freestanding . When a morpheme stands by itself, it is considered as a root because it has a meaning of its own (e.g. the morpheme cat) and when it depends on another morpheme to express an idea, it is an affix because it has a grammatical function (e.g. the--s in cats to indicate that it is plural). Every word comprises one or more morphemes . </P> <P> Every morpheme can be classified as either free or bound . These categories are mutually exclusive, and as such, a given morpheme will belong to exactly one of them . </P>
