Intimidate, daunt (7)
I believe the answer is:
overawe
I believe this is a double definition.
'intimidate' is the first definition.
(I've seen this in another clue)
'daunt' is the second definition.
(I've seen this before)
(Other definitions for overawe that I've seen before include "Or weave (anag.)" , "Impress someone into silence" , "Fill with astonishment" , "put off" , "Cow" .)
