Old English wearm (adjective), werman, wearmian (verb), of Germanic origin; related to Dutch and German warm, from an Indo-European root shared by Latin formus 'warm' and Greek thermos 'hot'.

  • Warm is an Old English word but can be traced right back to a root that was also the source of Greek thermos ‘hot’, which gave us thermometer (mid 17th century), thermostat (mid 19th century), and the Thermos flask (early 20th century). Cold hands, warm heart is a proverb first found in the early 20th century.
