Scoffs in great surprise (4)
I believe the answer is:
eats
'scoffs' is the definition.
(I've seen this before)
'in great surprise' is the wordplay.
'in' indicates a hidden word.
'EATS' can be found hidden inside 'great surprise'.
(Other definitions for eats that I've seen before include "Is not any faster" , "Ingests" , "Swallows food" , "Takes meals" , "Consumes with teas" .)
