Aristotle (1954:235) once came to a conclusion that all rhetoric phenomena can be ascribed to metaphorical language. In theory, metaphors may appear in a single word, a phrase, a sentence, a paragraph or even the whole essay. Each language is full of a great deal of euphemisms and proverbs, and Metaphor plays a crucial role in expressing point of views and exploring the world. The true value of metaphors is not only embodied in serving as a king of rhetoric device, but in being an important means of creating new words as well as expansion of meanings in order that ensure language acclimatize itself the ever-changing language utilization.

In conclusion, metaphor provides us with the opportunity to evince our cognitive activities and via these activities we are capable of making use full of a certain extent presented by one word or a phrase to be aware of another experience or conceptual extent.
