Deer at Hampton, perhaps? (3)
I believe the answer is:
roe
'deer' is the definition.
(roe deer is a kind of deer)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for roe that I've seen before include "Fish eggs; small deer" , "shy animal" , "If hard, eggs" , "Part of fish, sounds like go through water" , "Lobster's ripe ovary" .)
