I'm surprised the Church raised a sound response (4)
I believe the answer is:
echo
'a sound response' is the definition.
'echo' can be an answer for 'response' (echo is a kind of response). I am not sure about the 'a sound' bit.
'i'm surprised the church raised' is the wordplay.
'i'm surprised' becomes 'oh' (exclamation).
'the church' becomes 'CE' (Church of England).
'raised' shows that the letters should be reversed in order (going up in a down clue).
'oh'+'ce'='ohce'
'ohce' backwards is 'ECHO'.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Repeating of sound" , "Nymph (only able to repeat the last words of others)" , "Repeated sound" , "Before foxtrot" , "Reiterate" .)
