Recalled expression of surprise with church having acoustic feature (4)
I believe the answer is:
echo
'acoustic feature' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'recalled expression of surprise with church' is the wordplay.
'recalled' is a reversal indicator.
'expression of surprise' becomes 'oh'.
'with' means one lot of letters go next to another.
'church' becomes 'CE' (abbreviation for Church of England).
'oh'+'ce'='ohce'
'ohce' reversed gives 'ECHO'.
'having' is the link.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Reflected sound" , "Sound bouncing back" , "Repetition of sound" , "Send back" , "copy" .)
