Haiku (俳句, is a type of short form poetry originally from Japan. Traditional Japanese haiku consist of three phrases that contain a kireji, or “cutting word”, 17 on (a type of Japanese phoneme) in a 5, 7, 5 pattern, and a kigo, or seasonal reference. However, modern haiku vary widely on how closely they follow these traditional elements. https://en.wikipedia.org/wiki/Haiku
