An American elk or a Scottish rodent? (5)
I believe the answer is:
moose
'an american elk' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for moose that I've seen before include "Ungulate" , "Large US deer" , "Large N American deer like European elk" , "North American elk" , "North American deer" .)
