Noam Chomsky’s innateness theory explains language development by proposing that human beings are biologically equipped with an inborn capacity to acquire language. Chomsky developed this theory as a criticism of behaviorist explanations of language learning, particularly the view that language is acquired mainly through imitation, reinforcement, conditioning, and practice.

The LAD is a hypothetical, innate cognitive mechanism that enables children to process linguistic information and discover the grammatical rules of their language. When children are exposed to speech in their environment, the LAD helps them identify patterns and construct an internal system of grammar. Thus, language acquisition is not simply a matter of memorizing words or imitating
