Ripping ingrate apart (7)
I believe the answer is:
tearing
'ripping' is the definition.
(I've seen this in another clue)
'ingrate apart' is the wordplay.
'apart' is an anagram indicator (the word is broken apart).
'ingrate' anagrammed gives 'TEARING'.
(Other definitions for tearing that I've seen before include "'Pulling apart, ripping (7)'" , "Granite (anag.)" , "violent" , "splitting" .)
