Let it stand one way and in France (4)
I believe the answer is:
'let it stand' is the definition.
(I've seen this before)
'one way and in france' is the wordplay.
'one way' becomes 'st' (abbreviation for street).
'and' means one lot of letters go next to another.
'in france' becomes 'et' (I've seen this in other clues).
(Other definitions for stet that I've seen before include "Direction in printing to cancel a correction or deletion" , "Correction-reversing mark" , "Retain this type" , "Printing instruction: "Let it stand"" , "cancel amendment" .)
