Please paraphrase to simple English
The innatist perspective, advocated by Noam Chomsky, posits that language acquisition is innate and genetically predetermined. Chomsky's theory of universal grammar suggests that all humans have an innate ability to acquire language and that there are underlying rules and structures that govern all languages. According to this perspective, children are born with a language acquisition device (LAD) that enables them to learn language effortlessly and unconsciously. Research studies on language universals and the critical period hypothesis support Chomsky's theory on the innateness of language acquisition.
