To override something is to use your power or a stronger rule to cancel or replace it.
From “over” and “ride,” originally meaning to ride over or trample down. The figurative sense of overpowering a rule or decision developed later.
Override is the word of last resort—when a system, rule, or machine is doing the wrong thing, you force a new path. In technology, an override is both a safety tool and a risk, because it lets humans break the system’s own safeguards.
