Poetry is a form of literature composed in verse. It is normally rhythmic, metrical and there is division of stanzas. The use of imagery and figurative language gives it unique character.
Poetry is a collective name for the cluster of poems. It is one of the most ancient forms of arts. It is often fused with music in songs. It is its rhythmic use of language as a reason; it is often called “metrical writing”. But as we see, cadenced poetry of the Bible and free verse for example, are rhythmic but not metrical in strict sense of the term.
Broadly speaking, poetry usually projects emotions, feelings and human experience in metrical language.
