Tanka or haiku (4)
I believe the answer is:
poem
I believe this clue is a double definition.
'tanka' is the first definition.
(thesaurus)
'haiku' is the second definition.
(I've seen this in another clue)
(Other definitions for poem that I've seen before include "Piece of verse" , "Mope (anag.)" , "Ode" , "Literary composition, sometimes in verse" , "Mope about in verse" .)
