Final answer:
If you see the word stet in a circle in a margin next to a line, it means that the proofreader wants to keep that line as it is and not make any changes.
Step-by-step explanation:
If you see the word stet in a circle in a margin next to a line, it means that the proofreader wants to keep that line as it is and not make any changes. The word 'stet' is Latin for 'let it stand' and is commonly used in the editing process to indicate that a previously marked deletion or correction should be ignored.
For example, if a proofreader marks a word for deletion but later decides to keep it, they would write 'stet' in a circle next to that word. This is often done to ensure clarity and prevent confusion during the editing process.
