apurar
/apuˈɾaɾ/ · B1 · verb
to drain, use up completely
⏳ a + puro (pure): purify by boiling down to the last drop, so drain, then rush
From Latin purus, pure. To purify a liquid you reduce it until nothing is left, hence to drain or use up. Running out (of time, of patience) gives the other senses: to hurry someone, and to worry or pressure them.
