Greedy where flesh is involved? (7)
I believe the answer is:
selfish
'greedy' is the definition.
(greed is selfish)
'where flesh is involved?' is the wordplay.
'where' indicates anagramming the letters (I've seen this in other clues).
'involved?' is an insertion indicator.
'flesh' is an anagram of 'selfh'.
'selfh' enclosing 'is' is 'SELFISH'.
(Other definitions for selfish that I've seen before include "Mercenary" , "Concerned chiefly with one's own interests" , "Concerned only with self" , "Egocentric - mean" , "Putting own interests first" .)
