respiratorio
/respiɾaˈtoɾjo/ · B2 · adj
respiratory, breathing
🫁 respiratorio = re- (again) + spirare (breathe): breathing again and again
Spanish respiratorio comes from Latin respirare, built from re- (again) plus spirare (to breathe). Breathing repeats in cycles, so the re- fits. The same spirare appears in English spirit and inspire.
