🍲 caldera = cauldron: from Latin caldaria, 'for heating' (calidus = hot)
Spanish caldera comes from Latin caldaria, 'pot for heating,' related to calidus, 'warm.' Think of calor (heat) inside caldera: a vessel built for heat. The geological English 'caldera' is the same word, a huge cauldron-shaped volcanic basin.
