Noam Chomsky, known as the father of modern linguistics, has made a crucial contribution in the field of linguistics. He has opined that language has a strong biological basis, with children biologically prepared to learn a language at a certain time and in a certain way. Chomsky proposed the assumption that a child is born with an innate language learning capacity. He has also proposed 'Language Acquisition Theory' that is 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'.Language acquisition device is a hypothetical tool in children's brain that makes them able to:acquire and produce language.learn and assimilate the language easily.analyze language and extract basic rules.encode the grammatical structure of language.Hence, it could be concluded that Chomsky proposed the assumption that a child is born with an innate language learning capacity.Important Points Other Aspects of Chomsky's Theory:Innate abilityChomsky strongly believes that children born with an innate knowledge of grammar that serves as the basis for all language acquisition.Generative grammarAccording to Chomsky generative grammar refers to a finite set of rules to generate sentences and can be used to produce more sentences in that language.Universal grammarChomsky's universal grammar suggests that all children have an innate ability to acquire, understand, and develop grammar.
