Cape a huntsman might possess? (4)
I believe the answer is:
horn
'cape' 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 horn that I've seen before include "See 1 Across" , "Head growth; cornucopia" , "Musical instrument - antler" , "familiar to the matador?" , "Possession of huntsman or deer" .)
