Residents at home with partners (7)
I believe the answer is:
inmates
'residents' is the definition.
(inmate is a kind of resident)
'home with partners' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'with' means one lot of letters go next to another.
'partners' becomes 'mates' ('mate' can be a synonym of 'partner').
'in'+'mates'='INMATES'
'at' acts as a link.
(Other definitions for inmates that I've seen before include "Inhabitants" , "Ties man (anag.)" , "Prisoners" .)
