Usage-based linguistics

Usage-based linguistics explains linguistic structure as emerging from language use, learning, and experience. It emphasizes that patterns speakers acquire from repeated use shape grammar and linguistic knowledge.

Construction grammar: A family of linguistic theories that treats form–meaning pairings, from words to abstract patterns, as basic units of grammar. It models grammatical patterns as learned constructions rather than rules independent of use.
Linguistic experience: A person's accumulated exposure to language in comprehension, production, and interaction. It is the input history from which usage-based accounts explain individual linguistic knowledge.
Cognitive linguistics: An approach to language that studies linguistic structure as part of general cognition and conceptualization. Usage-based linguistics developed closely alongside cognitive linguistics and shares its emphasis on experience.
Generative grammar: A family of theories that models language with formal rules or principles capable of generating grammatical expressions. It contrasts with usage-based explanations over how much grammatical knowledge is abstracted from experience.
Statistical learning: Learning regularities in input by tracking the frequency and distribution of events. Sensitivity to recurring patterns helps explain how speakers extract structure from language exposure.
Corpus linguistics: The study of language through systematic analysis of large collections of recorded or written texts. Corpora reveal distributional patterns that usage-based theories connect to grammar.
Functional linguistics: Approaches to language that explain structure in relation to communicative functions and social use. Functional traditions helped establish language use as a source of explanation for linguistic structure.
Universal grammar: The hypothesis that humans possess innate linguistic principles shared across languages. Usage-based accounts generally assign learning and experience a larger role than innate language-specific structure.
Entrenchment (linguistics): The strengthening of a linguistic unit or pattern in memory through repeated use. Repeated use makes familiar forms easier to access and more established in an individual grammar.
Prototype theory: A theory of categorization in which members vary in typicality around especially representative examples. Graded categories help explain why frequent or typical expressions can shape linguistic generalizations.
