Rise and hover in the air (8)
I believe the answer is:
levitate
'rise and hover in the air' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for levitate that I've seen before include "Rise in the air, unsupported" , "Lift" , "Cause to rise and hover" , "Cause to float, spiritualist fashion" , "Rise and float in defiance of gravity" .)
