Noam Chomsky’s nativist linguistic theory suggests that language is an innate concept. Through his universal grammar concept, Chomsky believes that every human has a natural language ability. It means babies are born pre-equipped with language-learning systems. According to Chomsky, a single master language existed, and all the other languages originated from here. It means babies are born with the prerequisites for language learning. Chomsky refers to it as the Language Acquisition Device (LAD), and it allows children to acquire linguistic abilities quickly.
