Lune

     The lune was invented by Robert Kelly, who was unhappy with the western haiku. (the seventeen syllable 5-7-5 version) This was because English uses less syllables per word than Japanese (on average) The form he invented, named after French for "moon" because of its similarity to the crescent moon, had a pattern that better fit English still three lines, the syllabic scheme was
     5 - 3 - 5

     A poet, Jack Collom, loved this idea, especially when he began teaching children. The problem was he remembered it wrong. He taught
     3 - 5 - 3
words, not syllables
the form was easy to pick up for the children. 

Both are considered lunes.
