Reeled, amazed (9)
I believe the answer is:
staggered
I believe this clue is a double definition.
'reeled' is the first definition.
('stagger' can be a synonym of 'reel')
'amazed' is the second definition.
(staggering is a kind of amazing)
(Other definitions for staggered that I've seen before include "Astonished" , "Did floor" , "Lurched, reeled" , "Bowled over" , "not to be starting together" .)
