For Joseph May's eight word contest..

A rondeau (plural rondeaux) is a form of French poetry with 15 lines written on two rhymes. Variant forms may have 10 or 13 lines. It makes use of refrains, repeated according to a certain stylized pattern. It was customarily regarded as a challenge to arrange for these refrains to contribute to the meaning of the poem in as succinct and poignant a manner as possible. The rondeau consists of thirteen lines of eight syllables, plus two refrains (which are half lines, each of four syllables), employing, altogether, only three rhymes. It has three stanzas and its rhyme scheme is as follows: (1) A A B B A (2) A A B with refrain: C (3) A A B B A with concluding refrain C. The refrain must be identical with the beginning of the first line.
