Poetry is a literary work that uses distinctive style and rhythm to express feelings and ideas. Poems can have various structures, including stanzas of different line counts. Readers often make incorrect assumptions that a poem has a hidden message to decode rather than appreciating the sounds and emotions directly conveyed. Poems use techniques like descriptive language, rhyme, metaphor, and rhythm in various forms without always needing a specific structure. Common types of poems are lyric, which expresses personal feelings; narrative, which tells a story; and descriptive, which focuses on images of the external world.
