Girl got hour off to check and polish (4)
I believe the answer is:
edit
'polish' is the definition.
(I've seen this in another clue)
'girl got hour off to check' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'edi' and 'edi' is found within the answer.
A single letter 't' 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).
'and' is the link.
Can you help me to learn more?
(Other definitions for edit that I've seen before include "Alter text" , "Adjust text" , "be a bookmaker" , "Supervise - amend" , "doctor" .)
