Boyfriend; dandy (4)
I believe the answer is:
beau
I believe this is a double definition.
'boyfriend' is the first definition.
(synonyms)
'dandy' is the second definition.

(Other definitions for beau that I've seen before include "Dandy - attentive companion" , "Male admirer; dandy" , "Male suitor - dandy" , "Sweetheart" , "Dandy - lover" .)
