Uriah, beheaded, coming back: bit of a shock (4)
I believe the answer is:
awed
'shock' is the definition.
(I've seen this before)
'uriah beheaded coming back bit of a' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
The remaining letters 'wed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for awed that I've seen before include "Amazed" , "Inspired with wonder" , "Inspired with reverence" , "in terror" , "Overcome with wonder or amazement" .)
