Clodhopper (3)
I believe the answer is:
oaf
'clodhopper' is the definition.
(both can mean a clumsy person)
This is the entire clue.
(Other definitions for oaf that I've seen before include "Stupid or boorish man" , "Barbarian" , "Lout, dullard" , "A clumsy or stupid person" , "Awkward stupid person" .)
