What is the opposite of dele?

Answer 1

Caret (insert), or stet (cancel the delete). Dele is the name of the proofreader's mark (deleatur) that indicates to take something out (DELETE it). It's a line that runs through the material to be deleted and ends in a single loop that looks like a pig's tail. The proofreader's mark that indicates to INSERT something is the caret, which looks like an upside-down "V." So the opposite of "dele" could be "caret." Stet means "Let it stand as it was." It tells the typesetter to ignore whatever instructions were marked previously. It can negate instructions of many kinds, and is not the direct opposite of dele.
