1. Stanza: A stanza is a group of lines in a poem that are separated from other groups of lines by a space or indentation. Each stanza usually contains a complete thought or idea and follows a consistent rhyme scheme or meter.
2. Verse: In its general usage, verse refers to a line or group of lines in a poem. However, in some specific poetic forms, verse can also be used to refer to an entire stanza.
3. Strophe: Strophe is another term for a stanza, particularly in ancient Greek and Latin poetry.
4. Canto: A canto is a major division or section within a long narrative poem, such as an epic or a canto in Dante's Divine Comedy. Each canto typically covers a significant part of the story or narrative.
5. Episode: In narrative poetry, an episode refers to a distinct event, incident, or part of the story that forms a self-contained unit within the larger narrative.
6. Quatrain: A quatrain is a stanza consisting of four lines. Quatrains are often used in sonnets, hymns, and other poetic forms.
7. Tercet: A tercet is a stanza consisting of three lines. Tercets are commonly found in terza rima, a verse form where three-line stanzas are linked by a specific rhyme pattern.
8. Couplet: A couplet is a stanza consisting of two lines. Couplets are often used to create a sense of closure or emphasis at the end of a poem or stanza.
9. Line: A line is a single horizontal row of words in a poem. Lines in poetry can vary in length and meter and contribute to the overall rhythm and flow of the poem.
It's worth noting that not all poems may have these specific sections or divisions. Some poems may have their own unique structures or may deviate from traditional forms.
