Corrigendum is a noun that refers to an error.

The origin of corrigendum is in the Latin word corrigere (core ee GARE ay) which means ‘to bring into order’ or ‘to correct.’

As an editor, I often deal with writers who get frustrated when they see a corrigendum that embarrasses them. I always assure them that all writers have things that need be corrected. If they didn’t, I wouldn’t have a job.
