Situated outside entrance to temple, let it remain (4)
I believe the answer is:
stet
'let it remain' is the definition.
(I've seen this before)
'situated outside entrance to temple' is the wordplay.
'situated' becomes 'ste' (I am not sure about this - if you are sure you should believe this answer much more).
'outside' says to put letters next to each other (outside can mean adjacent to).
'entrance to' says to take the initial letters.
The first letter of 'temple' is 't'.
'ste'+'t'='STET'
Can you help me to learn more?
(Other definitions for stet that I've seen before include "Let it stand (on proof)" , "Printing instruction: "Let it stand"" , "leave things as they were" , "Leave in, as text" , "Ignore correction" .)
