"Let it stand" (4)
I believe the answer is:
stet
'let it stand' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stet that I've seen before include "Retainer" , "Let it stand (on proofs)" , "Leave in, as text" , "Direction in printing to cancel a correction or deletion" , "Notation for let spelling stand, don't change it" .)
