Loiter, having finished after husband (5)
I believe the answer is:
hover
'loiter' is the definition.
(thesaurus)
'finished after husband' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'after' means one lot of letters go next to another.
'husband' becomes 'h' (abbreviation).
'over' after 'h' is 'HOVER'.
'having' is the link.
(Other definitions for hover that I've seen before include "Hang in the air or waver" , "Fly over same spot" , "Remain in one place in the air" , "Be poised" , "sky - so remain there?" .)
