Fiancee at home being looked after (8)
I believe the answer is:
intended
'fiancee' is the definition.
(I've seen this before)
'at home being 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'**).
'being looked after' becomes 'tended' (I've seen this before).
'in'+'tended' is 'INTENDED'.
(Other definitions for intended that I've seen before include "Fiancé (e) - on purpose" , "One about to join union" , "Planned, meant to" , "Deliberate" , "no mistake!" .)
