Stag or roe (4)
I believe the answer is:
deer
I believe this clue is a double definition.
'stag' is the first definition.
(I've seen this before)
'roe' is the second definition.
(I've seen this in another clue)
(Other definitions for deer that I've seen before include "Eg, stag or doe" , "Bucks and does?" , "Hoofed grazing animal" , "Antler-bearing animal" , "The - Hunter, 1978 film" .)
