Roman counterpart of Aphrodite (5)
I believe the answer is:
venus
'roman counterpart of aphrodite' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for venus that I've seen before include "Aggrieved, peeved" , "Brightest planet" , "not really a star" , "Second nearest planet to the sun" , "Roman goddess of love" .)
