For the clever, propitious (6)
I believe the answer is:
bright
I believe this is a double definition.
'for the clever' is the first definition.
(bright can mean clever or gifted)
'propitious' is the second definition.
(thesaurus)
(Other definitions for bright that I've seen before include "Effulgent" , "Intelligent, lively" , "bubbly?" , "Illuminated" , "Shining (with intelligence)" .)
