The English word quinzaine come from the French word qunize, meaning fifteen. A quinzaine is an unrhymed verse of fifteen syllables.
These syllables are distributed among three lines so that there are seven syllables in the first line, five in the second line and three in the third line (7/5/3). The first line makes a statement. The next two lines ask a question relating to that statement.
