Knowledge of Chomsky's method and grammar is useful for a number of reasons. The field of linguistics and our understanding of language acquisition have greatly benefited from Noam Chomsky's theories. His theory of universal grammar, which holds that people possess an innate understanding of language, has significant implications for language learning and teaching. For example, as an English teacher, one can gain insight into how students learn language and produce grammatically correct sentences despite receiving limited input during the critical period of language development.

Teachers should pay particular attention to Chomsky's theoretical notion of the language acquisition device, a fictional instrument that speeds up children's language learning and internalization. It has ramifications for curriculum development and language instruction since it claims that all children are born with this natural process for acquiring language. An English teacher can improve their comprehension of the cognitive processes that underlie language acquisition by being acquainted with Chomsky's theories. This knowledge can then be used to instructional tactics and approaches that are used to teach grammar and language skills.

In addition, Chomsky's contributions have shaped contemporary techniques of teaching languages; many instructors are using more organic, immersive approaches that are consistent with universal grammar. An English teacher can stay up to date on language education trends and make well-informed decisions regarding teaching approaches that align with the most recent research and ideas by becoming knowledgeable with Chomsky's method and grammar.
To sum up, English teachers should become knowledgeable about Chomsky's approach and grammar since it offers insightful knowledge about universal grammar, language acquisition, and cognitive science. This knowledge can then be used to improve and guide language teaching methods.
