Description

Chomsky's Language Acquisition Theory

Chomsky proposed that humans are born with an innate ability to acquire language through a mechanism called the Language Acquisition Device (LAD). He also introduced the concept of universal grammar, which suggests that all languages share a common structural basis. Additionally, he emphasized the critical period for language learning, indicating that early childhood is the most effective time for language acquisition.
