Terrible greed with pie family (8)
I believe the answer is:
pedigree
'family' is the definition.
(I've seen this before)
'terrible greed with pie' is the wordplay.
'terrible' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'greed' put after 'pie' is 'piegreed'.
'piegreed' is an anagram of 'PEDIGREE'.
(Other definitions for pedigree that I've seen before include "List of ancestors" , "Line of descent, family tree" , "Blood line" , "Stock" , "Ancestral line" .)
