1. Emotional and imaginative content:
the first notable feature of poetry is that its content is emotional and imaginative. In fact, emotion and imagination are the essential qualities of poetry.it is said that “poetry is imaginative emotional interpretation of life". Poetry deals with facts , experiences and problems of life. First ,it relates them to our emotions and then transforms them by imagination. Poetry treats reality imaginatively. However, it does no falsify it. Imagination and emotion predominate poetry.
2. Metrical form (Rhythm):
the second essential characteristic of poetry is metre. Poetry is emotional and imaginative in substance and metrical in form. Metre means rhythmical language. In poetry ,the emotional and imaginative interpretation of life is clothed in rhythmical language. Like any art ,the function of poetry is to give aesthetic pleasure. And it is metre which enables poetry to perform this function properly.it is metre which primarily differentiates poetry from prose. Without metre, even the most imagination and emotion subject would remain prose. It is metre which function as the dividing line between prose and poetry. Great critic Matthew Arnold says “ metre must be taken as the general and constant characteristic of poetry and the chief point of distinction between prose and poetry.
