It is a fact that any new theory puts old questions into a new light. However, to achieve the goals of linguistic theory is what a linguistic theory should concern itself with whatever field it tackles. Optimality theory is a modern linguistic theory that aims at describing and explaining languages in a new framework. It is considered to be a radical departure from the derivational model of the previous versions of generative phonology. It assumes that grammars of individual languages draw their basic options from a set of universal constraints. It achieved universality by the ranking and the reranking of such constrains. These constraints are considered to be a detailed description of linguistic phenomenon in different languages.
