A robust overview of the explanatory vocabulary based on sound acquisition theory. Chomsky's universal grammar principle was the welcome. From a different angle he achieved in considering elements of vocabulary. He seems to be in an additional role. The objective of this essay is to prove such a point that this hypothesis not only depends on some of them. Each one has the feeling of understanding and integrating elements of the other if the vocabulary to be attained is fully accountable.
