Haiku

Begin with a thought and a kigo (seasonal metonym, either noun or phrase), arrange the thought around the kigo using 17 morae (syllable stresses) in metrical phrases of 5, 7, 5, place sensibly and pleasingly on three lines, with a natural keriji to end the thought or provoke emotion or meditation within it.


Baby bird fallen,
Mother sings, Father hovers
Wings flap -- infant soars!
