What is the difference between verse and stanza?

A stanza is two or more lines of a poem and verse is defined as a single line of a poem. In music, verse and stanza both refer to the part of the piece before the chorus.

A stanza does not need to be a particular number of lines, but stanzas usually have a recurring structure such as lines of the same length or with the same pattern of rhyming. The word "verse," derived from "versus" in Latin, may also be used to refer to "poetry" as opposed to "prose" and can also refer to a complete work of poetry.
