Meant to be at home, getting looked after (8)
I believe the answer is:
'meant' is the definition.
('intend' can be a synonym of 'mean')
'at home getting looked after' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'getting' means one lot of letters go next to another.
'looked after' becomes 'tended' (tending is a kind of looking after).
'to be' is the link.
(Other definitions for intended that I've seen before include "wanted from the outset" , "no mistake!" , "Person engaged" , "One about to join union" , "Fiancee (colloq.)" .)
