Bellow is some information on Haiku. If you find more feel free to post it here in this announcement. Much love: LunarHybrid.

Haiku (俳句) is a very short form of Japanese poetry typically characterised by three qualities:

* The essence of haiku is "cutting" (kiru). This is often represented by the juxtaposition of two images or ideas and a kireji or 'cutting word' between them, a kind of verbal punctuation mark which signals the moment of separation and colours the manner in which the juxtaposed elements are related.

* Traditional haiku consist of 17 on (also known as morae), in three phrases of 5, 7, and 5 on respectively. Any one of the three phrases may end with the kireji. Although haiku are often stated to have 17 syllables, this is inaccurate as syllables and on are not the same.

* A kigo (seasonal reference), usually drawn from a saijiki (歳時記), an extensive but defined list of such words. The majority of kigo, but not all, are drawn from the natural world. This, combined with the origins of haiku in pre-industrial Japan, has led to the inaccurate impression that haiku are necessarily nature poems.

In contrast to English verse typically characterized by meter, Japanese verse counts sound units known as "on" or morae. Traditional haiku consist of 17 on, in three phrases of five, seven, and five on, respectively. Among contemporary poems teikei (fixed form) haiku continue to use the 5-7-5 pattern while jiyuritsu (free form) haiku do not. But even the traditional haiku masters were not always constrained by the 5-7-5 pattern.

Although the word "on" is often translated as "syllable", in fact one on is counted for a short syllable, an additional one for an elongated vowel, diphthong, or doubled consonant, and one more for an "n" at the end of a syllable. Thus, the word "haibun", though counted as two syllables in English, is counted as four on in Japanese (ha-i-bu-n); and the word "on" itself, which English-speakers would view as a single syllable, comprises two on: the short vowel o and the moraic nasal n̩. In addition, some sounds, such as "kyo" (きょ) can be perceived as two syllables in English but is a single on in Japanese.

The word onji (音字; "sound symbol") is sometimes used in referring to Japanese sound units in English[9] although this word is no longer current in Japanese. In Japanese, each on corresponds to a kana character (or sometimes digraph) and hence ji (or "character") is also sometimes used as the count unit.
