Response from congregation almost put right (4)
I believe the answer is:
amen
'response from congregation' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'almost put right' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'put right' becomes 'amend' (I've seen this before).
'amend' with its final letter taken away is 'AMEN'.
Can you help me to learn more?
(Other definitions for amen that I've seen before include "Last word of prayer" , "Name for end to prayer" , "Word of approval" , "statement of affirmation" , "Churchgoer's assent?" .)
