A couple of females, clever and congenial (7)
I believe the answer is:
affable
'congenial' is the definition.
(I've seen this before)
'a couple of females clever' is the wordplay.
'couple of females' becomes 'ff' (two abbreviations for female).
'clever' becomes 'able' (able can mean skilled or talented).
'a'+'ff'+'able'='AFFABLE'
'and' acts as a link.
(Other definitions for affable that I've seen before include "Pleasant and friendly in manner" , "Pleasant to talk to" , "Polite and friendly" , "Showing friendly warmth" , "Amiable, genial" .)
