köken: From Middle High German van(e) m, from Old High German fano, from Proto-West Germanic *fanō, from Proto-Germanic *fanô (“cloth, flag”), from Proto-Indo-European *pān- (“fabric”). The shift to the feminine gender began in cognate Middle Low German vāne and, through Central German, established itself in the written language by the end of the 17th century.

Ich trage eine Fahne, Und diese Fahne ist rot. Es ist die Arbeiterfahne, Die uns die Einheit gebot.
köken: From earlier vendel (the present form with -aa- is likely influenced by vaan), likely an earlier borrowing from Middle High German venel, diminutive (with umlaut) of vane (German Fahne). By surface analysis, vaan + -el, with epenthetic -d- (compare Dutch daalder).
