Knight - Wikipedia

Etymology. The word knight, from Old English cniht ("boy" or "servant"), is a cognate of the German word Knecht ("servant, bondsman, vassal"). This meaning, of unknown origin, is common among West Germanic languages (cf Old Frisian kniucht, Dutch knecht, Danish knægt, Swedish knekt, Norwegian knekt, Middle High German kneht, all meaning "boy, youth, lad").
