The villanelle is a French verse form consisting of five three-line stanzas and a final quatrain, with the first and third lines of the first stanza repeating alternately in the following stanzas. These two refrain lines from the final couplet in the quatrain. Here's what that looks like (letters for rhyme scheme, numbers mean a line repeats): A1 B A2//A B A1//A B A2//A B A1//A B A1 A2 No theme, no prompt other than make it great.
