The term PROSE PIECES can be broken down into two crossword solutions: ESSAYS (6 letters) and POEMS (5 letters). Prose pieces are written works that are composed in sentences and paragraphs, as opposed to verse. ESSAYS are a type of prose piece that are typically used to express an opinion or make an argument. They are usually structured with an introduction, body, and conclusion. Poems are another type of prose piece that use rhythm, imagery, and other literary devices to convey emotion and meaning.
