cold

cold: [OE] Cold is a word of ancient roots. It can be traced back to the Indo-European base *gel-, *gol-, which also produced Latin gelu ‘frost’, ultimate source of English congeal, gel, and jelly. Its prehistoric Germanic descendant was *kal-, *kōl-, from which English gets cool, probably chill, and, via a past participial adjective *kaldaz, cold. The noun use of the adjective dates back to Old English times, but the sense ‘viral infection of the nose, throat, etc’ is a 16th- century development.
=> chill, congeal, cool, gel, jelly
