Being clumsy, comes in to a fanfare (3)
I believe the answer is:
oaf
'being clumsy comes' is the definition.
I can't judge whether this definition defines the answer.
'in to a fanfare' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OAF' is hidden within 'to a fanfare'.
Can you help me to learn more?
(Other definitions for oaf that I've seen before include "Lout; dolt" , "A clumsy boor" , "Idiot" , "Yahoo" , "Boor or lout" .)
