Word of the Day:

: an error in a printed work discovered after printing and shown with its correction on a separate sheet

Not only was the document itself full of errors, but the corrigenda included with it had mistakes as well!

If you guessed that "corrigendum" might be connected to the word "correct," you are quite right. Both "corrigendum" and "correct" derive from the Latin verb "corrigere," which means "to correct." The noun "corrigendum" and its plural "corrigenda" came to us unaltered from Latin in the early 19th century. The verb "correct" is much older; it has been part of our language since at least the 14th century. Other descendants of the very correct "corrigere" include "incorrigible" and "escort."
