the proof that comfort is just physics doing you a favor
means The quality or state of being warm, whether in temperature, feeling, or affection.
from From Old English 'wearmth,' built from 'wearm' (warm) plus the noun-making suffix '-th' — the same '-th' that quietly turns 'long' into 'length' and 'deep' into 'depth.' 'Wearm' itself traces back to a Proto-Germanic root and is related to words across the Germanic family for being warm; the deeper Indo-European cousins possibly link to roots meaning 'to burn' or simply 'to heat.' So the word is, fittingly, an old one — heat given a name long before anyone could explain it.
