Honestly, there is nothing nice about today’s word, calura (cah-loo-rah). Calura is more than simple heat, it’s unbearable heat. It’s what you get when it’s so hot you could bake cookies on the ground or fry your morning eggs on a car’s dashboard.
It comes from the vulgar Latin word calura, child of the verb calere, being hot. In Italian, we started using it in the 13th century, so it’s likely our Dante complained about the heat using this very word. It has the same root as caldo, hot, and calore, heat: they are all lexical siblings.
