The subtlety of language acquisition has been the most fundamental question in the study of linguistics and human development. From Bow-wow Theory to Yo-He-Ho Theory, the major theories on language origins and learnability emerged at mid-20th century and has been heavily debated ever since. Among them, the idea of universal grammar in which is usually credited to linguist Noam Chomsky, remains the most notable and controversial theory over time. He introduced and developed the t heory from 1950s to 1970s as he proposed and championed linguistic nativism in language acquisition. Chomsky supports that language mastery involves knowledge of linguistic rules and conventions, which he later named that as ‘cognizance’. He believes that …show more content…

There are totally 5 stages in children language development. Preverbal stage refers to the crying of 0 – 6 months old infants. This is followed by the “one-word” holophrastic stage in 7-12 months children where they imitate vowels to communicate, i.e. “da da” for daddy. By adding gestures (e.g. pointing) and intonation into their words, they can convey directions, spacious relations of the objects near them, making it the third stage in language development. After 18 months, children enter the telegraphic stage where they can use 2-word phrases to indicate their needs, for instance, “Papa! Milk!” which they later enter the final stage: the multi-word stage. In this stage, they make remarkable breakthrough in language comprehension and speech. No matter what the first language that children are exposed to, the majority of them stick to such linguistic developmental mechanism. With the support of other generative linguists and data of 5000 to 6000 languages all over the world, Chomsky has proved that despite their very different grammars, all of the languages are rooted with similar syntactic principles and rules. This shows the universality of language acquisition. It is clear that there is some unique device in human brains that isolates language learning from cultural and intelligence, make human innate to language acquisition; the environment only shapes the outline of such neurobiological system to a specific language.
