Something final to any buffoon (4)
I believe the answer is:
zany
'buffoon' is the definition.
(I know that zany is a type of buffoon)
'something final to any' is the wordplay.
I cannot quite understand how this works, but
'to any' could be 'any' and 'any' is present in the answer.
A single letter 'z' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for zany that I've seen before include "Screwball" , "Central African river" , "Clownish; wacky" , "Amusingly idiosyncratic" , "Left-field - foolish" .)
