Returning, I say, saw a Greek god (4)
I believe the answer is:
eros
'greek god' is the definition.
(Eros is an example)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "Statue of love-god in Piccadilly Circus in London" , "Arrow shooter" , "In Greek myth, the god of love" , "Name given to statue" , "Group of instincts" .)
