Hang over; loiter (5)
I believe the answer is:
hover
I believe this clue is a double definition.
'hang over' is the first definition.
(I've seen this before)
'loiter' is the second definition.
(thesaurus)
(Other definitions for hover that I've seen before include "Remain stationary while aloft" , "Remain suspended" , "Float above in the air, perhaps a craft" , "What some cross-Channel craft do" , "Hang in the air or waver" .)
