Belittle being anti-greed perhaps (9)
I believe the answer is:
denigrate
'belittle' is the definition.
(I know that belittle can be written as denigrate)
'anti-greed perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'anti'+'greed'='antigreed'
'antigreed' is an anagram of 'DENIGRATE'.
'being' is the link.
(Other definitions for denigrate that I've seen before include "Criticise, belittle" , "Blacken" , "put down" , "Run down" , "Unfairly criticise" .)
