adjectivelike

Adjectivelike refers to forms that function similarly to adjectives in syntax and meaning, even though they may arise from other word classes or have different morphosyntactic properties. In linguistic analysis, adjectivelike items can modify nouns, occur in attributive positions before a noun, participate in predication, and convey qualitative or descriptive content, much like true adjectives. They often originate from verbs (participles) or nouns (denominal forms), so they are not always canonical adjectives in origin, but they behave like adjectives in use.

Key criteria for adjectivelike status include distribution, degree modification, and predication. Adjectivelike forms typically appear directly before a noun as modifiers (the broken vase), may take degree modifiers (a very broken vase, more broken than the others), and can predicate about a subject (The vase is broken). Inflection and agreement patterns can vary: some adjectivelike forms inflect or agree like adjectives in certain languages, while in others their inflection is limited or non-existent. Examples in English include broken, sleeping, wooden, and world-famous, where the form derives from a verb or noun but functions adjectivally.

Adjectivelike phenomena are of interest in linguistics and natural language processing because they illuminate the boundaries between word classes and the flexibility of word formation. Cross-linguistic variation is common: some languages treat participles as a distinct category separate from adjectives, while others merge them into a unified adjectival system. Understanding adjectivelike items aids in parsing, morphological tagging, and the study of language acquisition and change.
