redondo
/reˈdondo/ · B2 · adj
round
⚽ redondo = re- + rotundus (Latin 'wheel-shaped'), so round like a wheel
Redondo comes from Latin rotundus, itself from rota, 'wheel'. The sound 'rotund' became 'redond'. Round numbers and a 'round' success (negocio redondo, a perfect deal) extend the sense of a complete circle with nothing missing.
