Noam Chomsky, known as the father of modern linguistics, has made a crucial contribution in the field of linguistics. He has proposed 'Language Acquisition Theory' that is primarily related to language development.According to Chomsky, 'set of rules in the mind of humans' is known as universal grammar. Chomsky emphasizes that 'children have an innate universal grammar' which helps them in:acquiring and understanding grammar regardless of where or how they are raised.developing grammatical sentence structures independence of sensory experience.serving as the basis for all languages, despite the existing differences between them.Hence, it could be concluded that the Universal Grammar theory of Chomsky states that we're all born with an innate understanding of the way language works.
