God of passion
I believe the answer is:
eros
'god of passion' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eros that I've seen before include "Greek equivalent to Roman Cupid" , "Cupid, son of Aphrodite" , "capital statue" , "Rose for the love-god" , "Asteroid - Greek god of love" .)
