Reportedly, what Cupid has for lover (4)
I believe the answer is:
beau
'for lover' is the definition.
(beau is a kind of lover)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for beau that I've seen before include "An old boy friend like Brummel?" , "An old-fashioned boy friend (4)" , "One loving" , "Sweetheart" , "Handsome young lover" .)
