warn: [OE] Warn, and its German relative warnen, go back to a prehistoric West Germanic *warnōjan. This was formed from the base *war- ‘watch, be on one’s guard, take care’, which also produced English ward, ware, wary, etc. Germanic *warnjan, which evidently had close links with *warnōjan, was borrowed into French, and surfaced in English as garnish. => garnish, ward, ware, wary
warn (v.)
Old English warnian "to give notice of impending danger," also intransitive, "to take heed," from Proto-Germanic *warnon (cognates: Old Norse varna "to admonish," Old High German warnon "to take heed," German warnen "to warn"), from PIE *wer- (5) "to cover" (see weir). Related: Warned; warning.
