More elaborate lover (7)
I believe the answer is:
fancier
I believe this is a double definition.
'more elaborate' is the first definition.
('fancy' can be similar in meaning to 'elaborate')
'lover' is the second definition.
(fancier is a kind of lover)
(Other definitions for fancier that I've seen before include "connoisseur" , "More highly decorated" , "More baroque" , "one imagines" , "More elaborate - lover (of pigeons, for instance?)" .)
