interés
/inteˈɾes/ · A2 · noun · m
interest
💰 interés = interest with the stress on the end: in-te-RÉS
From Latin interesse, to be between or to matter (inter = between + esse = to be). Same root as English interest, and it covers the same three senses: bank interest, curiosity, and a stake in something. The accent mark shows the final-syllable stress.
