The quality or state of being warm or hot; warmth or heat.
From Latin caliditas, formed from calidus (warm) plus the -itas suffix, a standard Latin method for forming abstract nouns. The term appears in medieval philosophical and medical texts discussing the properties of substances.
Medieval doctors actually believed in measuring calidity as a medical property—they ranked foods and medicines by their heat, and this abstract noun captures that long-lost medical philosophy about balancing your body's internal temperature.
