A woman's religion (5)
I believe the answer is:
faith
I believe this clue is a double definition.
'a woman's' is the first definition.
'religion' is the second definition.
(I know that religion can be written as faith)
(Other definitions for faith that I've seen before include "Religious belief" , "Strong belief in a supernatural power" , "religion" , "A woman" , "Total trust" .)
