What is what does stet mean?

"Stet" is a proofreading term that means to let the original text stand, despite any changes or corrections that have been suggested. It comes from the Latin phrase "stet litera," which translates to "let the letter stand." When an editor or proofreader comes across a correction that they feel is unnecessary or incorrect, they may indicate that the original text should remain by writing "stet" in the margin or next to the text. This indicates to others that the editor has reviewed the text and has intentionally decided to keep it as is.
