House needed by this writer for domicile (4)
I believe the answer is:
home
'domicile' is the definition.
('home' can be a synonym of 'domicile')
'house needed by this writer' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'needed by' means one lot of letters go next to another.
'this writer' becomes 'me' (the person who is writing these clues**).
'ho'+'me'='HOME'
'for' is the link.
(Other definitions for home that I've seen before include "Living place" , "It's where the heart is, they say" , "birthplace" , "Be it ever so humble, there's no place like it" , "chez nous?" .)
