At home looked after fiancee (8)
I believe the answer is:
'fiancee' is the definition.
(I've seen this before)
'at home looked after' is the wordplay.
'at' says to put letters next to each other.
'home' becomes 'in' ('he's home' can mean 'he's in'**).
'looked after' becomes 'tended' (tending is a kind of looking after).
'in' put next to 'tended' is 'INTENDED'.
(Other definitions for intended that I've seen before include "Fiancé (e) - on purpose" , "The boyfriend" , "Informally one's fiance or fiancee" , "Fiance (e) - on purpose" , "Fianc(e) - proposed" .)
