Deer relatives (4)
I believe the answer is:
elks
'deer relatives' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elks that I've seen before include "Large deer of Europe and N America" , "Moose" , "Moose(s)" , "Large deer with flattened antlers" , "Large deer of Northern Europe" .)
