According to Chomsky, what describes the innate ability to use language?

The concept describing the innate ability to use language, according to Noam Chomsky, is referred to as the Language Acquisition Device (LAD). This idea posits that humans are born with an inherent capacity for language learning, which includes a set of grammatical rules or structures common to all languages. The LAD allows children to acquire language naturally and rapidly during a critical period of development, demonstrating that the ability to understand and produce language is not solely learned through imitation or environmental interaction, but is also rooted in our biology.

Chomsky's theory emphasizes that while children are exposed to language, their capacity to learn and generate language stems from this internal mechanism. This foundational perspective laid the groundwork for much of modern linguistic theory and our understanding of cognitive development in relation to language learning.
