Prose is language that follows the natural flow or rhythm of speech, ordinary grammatical structures, or, in writing, typical conventions and formatting. Thus, prose ranges from informal speaking to formal academic writing. Prose differs most notably from poetry, which follows some type of intentional, contrived, artistic structure. Poetic structures vary dramatically by language; in English poetry, language is often organized by a rhythmic metre and a rhyme scheme.
The ordinary conversational language of a region or community, and many other forms and styles of language usage, fall under prose, a label that can describe both speech and writing. In writing, prose is visually formatted differently than poetry. Poetry is traditionally written in verse: a series of lines on a page, parallel to the way that a person would highlight the structure orally if saying the poem aloud; for example, poetry may end with a rhyme at the end of each line, making the entire work more melodious or memorable. Prose uses writing conventions and formatting that may highlight meaning—for instance, the use of a new paragraph for a new speaker in a novel—but does not follow any special rhythmic or other artistic structure.
