Exploit of female put away (4)
I believe the answer is:
Here is my best explanation:
'exploit' is the definition.
('feat' can be a synonym of 'exploit')
'female put away' is the subsidiary indication.
'female' becomes 'f' (abbreviation).
'put away' becomes 'eat' (I've seen this in other clues**).
'of' is the link.
(Other definitions for feat that I've seen before include "remarkable achievement", "Deed; achievement", "Great achievement", "Achievement needing skill, strength, etc.", "An achievement", "Notable act", "Accomplishment", "Courageous act", "Remarkable achievement of fate" and "Achievement of fate".)
