However, you could consider these options:
* "Octave and a Half": Since 28 lines is two octaves (8 lines each) plus 12 extra lines. This is playful and descriptive.
* "Long Sonnet": This refers to a sonnet (14 lines) extended to twice its length. It's a good fit if the poem has a sonnet-like structure.
* "Free Verse": If the poem doesn't follow a strict rhyme scheme or meter, "free verse" is a broad term that fits.
* "Descriptive Poem": If the poem's main focus is on describing something, this term captures its essence.
* "Narrative Poem": If the poem tells a story, "narrative poem" is suitable.
Ultimately, the best way to name a 28-line poem is to consider its content, structure, and your artistic intent.
