Fawn or stag (4)
I believe the answer is:
deer
I believe this clue is a double definition.
'fawn' is the first definition.
(thesaurus)
'stag' is the second definition.
(I've seen this in another clue)
(Other definitions for deer that I've seen before include "Ruminant(s) -- breed of 13 down" , "The male has antlers" , "Hoofed mammal" , "Antler-bearing animal" , "Hoofed animals" .)
