Share accommodation with husband, not much company to begin with (7)
I believe the answer is:
cohabit
'share accommodation' is the definition.
(I've seen this before)
'husband not much company to begin with' is the wordplay.
'husband' becomes 'h'.
'not much' becomes 'a bit' (a bit can mean a small amount).
'company' becomes 'co' (abbreviation).
'to begin with' is a charade indicator (letters next to each other).
'h'+'abit'='habit'
'habit' put after 'co' is 'COHABIT'.
'with' acts as a link.
(Other definitions for cohabit that I've seen before include "What to do with partner" , "become bedfellows" , "House-share" , "Live together as unmarried couple" , "Share a property" .)
