Chomsky theorized the existence of what concept related to language?

Noam Chomsky proposed the concept of Universal Grammar, which suggests that the ability to acquire language is innate to humans and that all languages share a common underlying structure. This theory posits that children are born with an inherent understanding of the principles governing the structure of language, allowing them to learn their native language more easily and rapidly than if they were simply taught through imitation or reinforcement. Universal Grammar emphasizes that despite the vast diversity of languages, there are core grammatical principles that are universal to all human languages. This idea has significantly influenced the fields of linguistics, psychology, and cognitive science, shaping our understanding of language acquisition and development.
