Prose simply refers to language written in sentences and paragraphs rather than verse (i.e. language other than poetry). It applies to all language without a regular rhythmic pattern or metrical structure.
“It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.”
The first sentence of Jane Austen’s Pride and Prejudice is an excellent example of prose.
“My mistress’ eyes are nothing like the sun / Coral is far more red than her lips’ red: / If snow be white, why then her breasts are dun; / If hairs be wire, black wires grow on her head” (lines 1-4).
- These lines from Shakespeare’s Sonnet 130 are an example of verse.
