the minimal meaningful part of an utterance and one of the basic units of a language system. The characteristics of morphemes are meaningfulness—morphemes convey lexical or grammatical meaning; repeatability—morphemes retain the same (or similar) meaning and the same (or similar) form when they appear in different contexts; and nonreducibility— morphemes cannot be further divided into parts having the same characteristics. The morpheme is also defined as the smallest meaningful part of a word and as a class of morphs possessing specific characteristics.

The detection of a morpheme begins with the division of utterances in a language into morphs; then, morphs similar in content and form and found in complementary or noncontrastive distribution (not causing differences of meaning) are combined into a single morpheme. For example, the Russian morpheme drug, “friend,” has the morphs drug~druzh~druz’ This level of analysis, which establishes the allomorphs of a single morpheme, is called identification. Identification is followed by the classification of the morpheme. According to their position in the language system, morphemes are divided into free morphemes capable of behaving as independent words, such as English day, German Tag, and Russian tikh; bound morphemes that occur only as part of a word, such as the plural formant -s in English days, or the adjectival ending -ii in Russian tikhii, “quiet“); and relatively bound morphemes that may occur in both free and bound form, such as Russian do, used as preposition and as prefix, in doletef do reki, “to fly up to the river.”

Morphemes are divided by function into auxiliary (affixal) and nonauxiliary (radical), of which the former are usually bound and the latter free. As a rule, the number of affixal morphemes is limited to a few dozen, while the number of radical morphemes is unlimited. Affixal morphemes are divided according to types of meaning conveyed, into derivational (word-forming), relational (word-altering, or inflectional), and relational-derivational (form-creating). The last two categories are often combined under the term “word-altering.”

Morphemes may convey meaning not only by their phonological presence in a given word but also by their absence (zero ending, zero allomorph). For example, the Russian word stol, “table,” is construed as nominative singular since it lacks the morphemic plural marker -y (Russian stoly, “tables“) as well as any relational morphemes indicating oblique case (the sign for zero ending is -#, as in stol[-#]). Most linguists regard the morpheme as a unit that correlates linguistic expression with linguistic content, that is, as a two-sided semiotic unit. Less often, the morpheme is regarded as the smallest unit of linguistic expression.
