The triolet is a short poem of eight lines with only two rhymes used throughout.

In a triolet, the first line is repeated in the fourth and seventh lines; the second line is repeated in the final line; and the final words from the first two lines are used to complete the tight rhyme scheme.

The line structure is: ABaAabAB, where the capital letters show the repeated lines.

The triolet is French in origin, and likely dating to the thirteenth century. It is closely related to the rondeau, another French verse form emphasising repetition and rhyme.
