A moral tale about female being friendly (7)
I believe the answer is:
affable
'friendly' is the definition.
('affable' can be similar in meaning to 'friendly')
'a moral tale about female' is the wordplay.
'moral tale' becomes 'fable' (I've seen this before).
'about' means one lot of letters go next to another.
'female' becomes 'f' (abbreviation).
'fable' after 'f' is 'ffable'.
'a'+'ffable'='AFFABLE'
'being' acts as a link.
(Other definitions for affable that I've seen before include "Pleasant and easygoing" , "Genial and friendly" , "Pleasant and friendly in manner" , "Congenial, easy to walk" , "benign" .)
