"the system of word-level devices (affixes etc.) used by a language for signaling grammatical categories like tense, number, person; the structure of certain closed paradigmatic sets like personal pronouns." Inflectional morphology has two broad functions: (a) the actual marking of grammatical categories on words, and (b) establishing linkages of various kinds between items in the sentence or discourse, such as agreement or concord, government, and anaphora.
