corrigendum (n.)

mid-14c., "to set (someone) right by punishing for a fault or error, to discipline;" late 14c., of texts, "to bring into accordance with a standard or original," from Latin correctus, past participle of corrigere "to put straight, attempt to make (a crooked thing) straight, reduce to order, set right;" in transferred use, "to reform, amend," especially of speech or writing, from assimilated form of com-, here perhaps an intensive prefix (see com-), + regere "to lead straight, rule" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule").

Meaning "to remove or counteract the operation of" is from late 14c. Related: Corrected; correcting.
