Klutzy type (3)
I believe the answer is:
oaf
'klutzy type' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oaf that I've seen before include "Clod" , "Stupid or boorish man" , "Stupid or loutish person" , "A clumsy or stupid person" , "Lout, dullard" .)
