Bite from bloodied general (4)
I believe the answer is:
edge
'bite' is the definition.
(I've seen this in another clue)
'from bloodied general' is the wordplay.
'from' says the answer is hidden in the clue.
'EDGE' is hidden in the letters of 'bloodied general'.
(Other definitions for edge that I've seen before include "Sharp side of a blade" , "Some bordering" , "Excitement; boundary" , "Bite" , "'Margin, rim (4)'" .)
