The Goat (9)
I believe the answer is:
capricorn
'the goat' is the definition.
(the goat in the zodiac)
This is all the clue.
(Other definitions for capricorn that I've seen before include "Tropic - Zodiac sign" , "Goat star sign" , "It's a Tropic, and the Sign of the Goat" , "Sign of winter" , "Constellation known as The Goat" .)
