Noam Chomsky, known as the father of modern linguistics, has made a crucial contribution in the field of linguistics. He has proposed theories that are primarily related to language development. According to Chomsky, an innate capacity to acquire language is the result of our uniquely human biological inheritance which is called the 'Language Acquisition Device'. A language acquisition device is a hypothetical tool in a child's brain that makes learners able to:acquire and produce language.learn and assimilate language easily.analyze language and extract basic rules.encode the grammatical structure of language.Hence, it could be included that according to Chomsky, human beings are born with a 'Language Acquisition Device' which helps to learn a language.Additional Information Other important concepts given by Noam Chomsky:Innate ability: He strongly believes that children are born with an innate knowledge of grammar that serves as the basis for all language acquisition.Generative grammar: According to Chomsky it refers to a finite set of rules to generate sentences and can be used to produce more sentences in that language.Universal grammar: Chomsky's universal grammar suggests that all children have an innate ability to acquire, understand, and develop grammar.Other theorists:According to Vygotsky, the most important part of language learning is "Social interaction".Skinner believed that children learn language through imitation and reinforcement.
