If rebuffed, stay at home (8)
I believe the answer is:
fireside
'home' is the definition.
(fireside is a kind of home)
'if rebuffed stay' is the wordplay.
'rebuffed' says the letters should be written backwards.
'stay' becomes 'reside' (I've seen this in other clues).
'if' written backwards gives 'fi'.
'fi'+'reside'='FIRESIDE'
'at' acts as a link.
(Other definitions for fireside that I've seen before include "in the home" , "focus for domesticity" , "warm, cosy place" , "One warmed by this" , "Hearth area" .)
