Japanese verse form (5)
I believe the answer is:
haiku
'japanese verse form' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for haiku that I've seen before include "Jap 17-syllable poem" , "17-syllable Japanese verse form" , "Seventeen-syllable Japanese poem" , "Short Japanese poem" , "Japanese poem of seventeen syllables comprising three lines" .)
