Request to remain true to type? (4)
I believe the answer is:
stet
'type?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for stet that I've seen before include "Instruction to ignore amendment" , "leave things as they were" , "Notation meaning leave as is, don't change spelling" , "Printer's annotation - let it stand" , "Ignore crossing" .)
