resfriado
/resˈfɾjado/ · B2 · adj
afflicted with the common cold
🤧🥶 resfriado = re- + enfriar (to chill): you got chilled, now you're sniffling
Resfriado comes from resfriar, built from re- (again, thoroughly) + enfriar (to cool, from frío, cold). Being thoroughly chilled gives you a cold, so the word names both the illness and the state of having caught one: estoy resfriado, I have a cold.
