Exaggeration is a rhetoric picture which is often used to arrange the speech and to attract the audience. In exaggeration, the poet, shows his meanings by the use of two methods, to make the subject greater or smaller, and in fact he develops his speech by the use of these rhetorical devices and emphatics in order to make the meaning more understandable.
Most rhetoricians, as they introduce the exaggeration, emphasize that it is in fact a kind of lie mixed with superstitions and therefore they sometimes have praised it and they have considered it as one of the basic elements of poetry and heightened speech and they have sometimes rejected it and considered it separate from the real poetry.
