Generativism refers to the theory of language developed by Noam Chomsky and his followers. It holds that language is innate and that humans possess a language acquisition device. Chomsky argued against behaviorism, proposing that language is not learned through stimulus and response. Instead, he believed that humans are born with an innate, universal grammar that allows children to learn language quickly despite limited exposure. Generativism also distinguishes between competence, the innate linguistic knowledge, and performance, how language is produced and understood. It views language as rule-governed and creative.
