Final answer:
Noam Chomsky believed that children are born with an innate capacity for language acquisition, known as the Language Acquisition Device (LAD), and that exposure to language in early childhood is crucial for language development.
Step-by-step explanation:
According to Noam Chomsky, language acquisition occurs most especially because of exposure to language in early childhood. Chomsky posited that we have an innate capacity to learn language, which he termed the Language Acquisition Device (LAD).
This biological predisposition for language suggests that while reinforcement such as parental feedback plays a role, children are inherently equipped to learn language. Indeed, the process is both a product of nature and nurture, with a biological determination underpinning the ability to learn language that is enhanced by interaction within a linguistic environment.
