Leave bewildered (4)
I believe the answer is:
daze
'leave bewildered' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for daze that I've seen before include "bowl over" , "Confused state unable to think clearly" , "can turn out to be stunning?" , "State of stupefaction" , "State of stunned confusion or bewilderment" .)
