consumidor
/konsumiˈdoɾ/ · B2 · adj
consumer
🛒 consumidor = consumir (to consume) + -dor (one who) = one who consumes
Spanish -dor marks an agent, like English -er. Consumir comes from Latin consumere, to use up. So consumidor is literally the one who uses things up, a consumer, and it can also describe something that consumes.
