Although "verse" is used in the real world to name a group of lines in a song (as in "Verse, Chorus, Verse, Chorus, Bridge, Verse, Chorus"), in poetry it means "single line." A group of verses is called a stanza or a verse paragraph. You'll impress English teachers by using the terms precisely.
The other meaning for verse is more general: it's sometimes used of metrical writing of all sorts: in other words, for poetry in general, as distinct from prose.

Three question marks mean I have to write more on the subject. Bear with me.
