Home before time, wound up fiancé (8)
I believe the answer is:
intended
'fiance' is the definition.
(someone's intended is their fiance)
'home before time wound up' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'before' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'wound up' becomes 'ended' (how things 'wind up' is how they end).
'in'+'t'+'ended'='INTENDED'
(Other definitions for intended that I've seen before include "Set out" , "wanted from the outset" , "Deliberate" , "Fianc(e) - proposed" , "Fiancé (e) - on purpose" .)
