The traditional language of the "région" is Alsatian, an Alemannic dialect of Upper German spoken on both sides of the Rhine and closely related to Swiss German. Some Frankish dialects of West Central German are also spoken in "Alsace Bossue" and in the extreme north of Alsace. Neither Alsatian nor the Frankish dialects have any form of official status, as is customary for regional languages in France, although both are now recognized as languages of France and can be chosen as subjects in lycées.
