Nonadjectives

Nonadjectives is a label used in some linguistic discussions and teaching materials to refer to all words whose primary grammatical category is not an adjective. It is not a formal universal class in most grammars, but a pragmatically defined grouping that helps contrast adjectives with everything else, especially in discussions of sentence structure, semantics, or computational tagging. The exact set of nonadjectives depends on the language and the analytic framework being used.

In English, nonadjectives typically include nouns (cat), verbs (run), adverbs (quickly), pronouns (they), determiners (this, those), prepositions (in), conjunctions (and), interjections (oh), numerals (three), and particles (not). Some words can perform multiple grammatical functions; for example, a word commonly treated as an adjective in one context might function as an adverb or a noun in another. In such cases, its classification as a nonadjective can be context-dependent, particularly in corpus analyses or part-of-speech tagging.

Applications of the nonadjective concept include corpus linguistics, natural language processing, and language teaching, where it serves as a convenient way to discuss everything outside adjectives. However, the boundary between adjectives and nonadjectives is not universal and can vary by language, theory, and even by function within a sentence. When used, the term should be defined explicitly for clarity and reproducibility.
