Edit delivered at noon (5)
I believe the answer is:
amend
'edit' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for amend that I've seen before include "Put right" , "Alter in writing" , "Change to improve" , "Modify - edit" , "Correct error, make minor alteration as to writing" .)
