Etymology
The phrase "to cancel a reservation" combines "cancel," derived from the Latin 'cancellare,' meaning to cross out or make void, with "reservation," which comes from the Latin 'reservare,' meaning to keep back or save. The phrase emerged as booking systems developed, allowing people to revoke their prior commitments.
