Stupid person accepts fine offering (4)
I believe the answer is:
gift
'offering' is the definition.
(I've seen this before)
'stupid person accepts fine' is the wordplay.
'stupid person' becomes 'git' (git can mean an annoying person).
'accepts' means one lot of letters goes inside another.
'fine' becomes 'f' (abbreviation).
'git' going around 'f' is 'GIFT'.
(Other definitions for gift that I've seen before include "A present or gratuity" , "A natural attribute" , "Offering" , "Endowment" , "Special aptitude - present" .)
