refresco
/reˈfɾesko/ · B2 · noun · m
soda, soft drink
🥤 refresco = re + fresco (cool, fresh): a drink that makes you fresh again
From refrescar, to cool down or freshen up. Fresco means cool or fresh, as in English fresco, a painting on fresh plaster. So a refresco is literally a re-cooler, and in everyday Spanish that usually means a soda.
