Chomsky's concept of 'Universal Grammar' suggests what about human languages?

Chomsky's concept of 'Universal Grammar' proposes that despite the apparent diversity of languages around the world, all human languages share a common structural basis. This idea posits that certain grammatical principles are innate to the human mind, suggesting that there are fundamental characteristics and rules that underpin all human languages. The concept of Universal Grammar implies that, regardless of the specific language being spoken, there exists a shared cognitive framework that supports language acquisition, which allows children to effortlessly learn the grammar of their native language.

This framework highlights the similarities between languages, such as the presence of nouns, verbs, and the ability to form questions or negatives, despite the variations in syntax and vocabulary. Understanding this commonality provides insights into how children can acquire complex language structures even with limited exposure, supporting the idea that language learning is facilitated by an inherent capability rather than being solely dependent on explicit instruction or imitation.
