oír
/oˈiɾ/ · A1 · verb
to hear
👂 oír ← Latin audire, same root as audio — the d dropped out, leaving o-ír
Latin audire (to hear) gave English audio, audible and audience. Spanish wore it down: au became o and the d fell away, leaving oír. Say it as two beats, o-EER, and the EER sits close to English ear.
