A woman's happiness (8)
I believe the answer is:
felicity
I believe this clue is a double definition.
'a woman's' is the first definition.
'happiness' is the second definition.
(I know that happiness can be written as felicity)
(Other definitions for felicity that I've seen before include "Girl" , "happy event" , "Intense joy" , "Complete happiness" , "Joy -- eloquence" .)
