Housewife's talk, not entirely joyous (6)
I believe the answer is:
festal
'joyous' is the definition.
('festal' can be similar in meaning to 'joyous')
'housewife's talk not entirely' is the wordplay.
'not entirely' indicates a hidden word.
'FESTAL' can be found hidden inside 'housewifes talk'.
(Other definitions for festal that I've seen before include "Relating to a holiday" , "Jovially celebratory" , "Jovial" , "Joyous, festive" , "Relating to a festival; joyous" .)
