Change at midday? (5)
I believe the answer is:
amend
'change at midday?' is the definition.
'amend' can be an answer for 'change' (amending is a kind of changing). I'm not certain of the 'at midday?' bit.
'change at midday?' is the wordplay.
I cannot really see how this works, but
'change' could be 'end' (ending is a kind of changing) and 'end' is found within the answer.
'midday?' could be 'm' and 'm' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for amend that I've seen before include "Revise" , "Modify, correct" , "Correct (one's ways)" , "make an improvement" , "Make minor improvements to (something)" .)
