The document discusses the difference between prose, poems, and poetry. Prose uses ordinary language without a metrical structure, while a poem uses language arranged in a rhythmic and metrical pattern to express ideas or emotions. Poetry is a type of literature that uses language and form to evoke emotional responses. The document examines Coleridge's view that poetry is an activity of the mind that can exist without meter or form, and a poem is a verbal expression of that activity. It concludes that a work cannot be defined as a poem or prose solely based on rhyme and meter, but also by its ultimate purpose and the effect it aims to achieve.
