Male mink (4)
I believe the answer is:
boar
'male mink' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for boar that I've seen before include "Male swine" , "Resting place for birds or bats" , "Wild swine" , "Wild animal, sounds like drill" , "Uncastrated male hog" .)
