cancelar

To cancel — used for appointments, events, subscriptions, and debts (cancelar una deuda, to pay off/settle a debt, especially in Latin America). Extremely common, everyday verb with a straightforward regular conjugation.

• Tuvimos que cancelar el vuelo por la tormenta. — We had to cancel the flight because of the storm.
• Ya cancelé la suscripción del gimnasio. — I already canceled the gym subscription.
• Canceló la deuda antes de fin de mes. — He paid off the debt before the end of the month.

In much of Latin America, cancelar can mean "to pay off/settle" a bill or debt, not just "to call off" — a learner who only knows the "call off" sense may be confused seeing cancelar used at a store checkout or on an invoice.

• expression Cultura de la cancelación — The Spanish-language name for "cancel culture," the social-media phenomenon (widely discussed since around 2015 and amplified by the #MeToo movement) of publicly withdrawing support from a person or brand over conduct seen as offensive — cancelar a alguien is now common everyday usage for this specifically.
