 Even now there are families, usually those in which both parents are of a German lineage, in which this dialect is still spoken on a regular basis and owners of businesses who speak the dialect may conduct business with it on occasion.This rigid demarcation of a dialect is called an "isogloss" and is remarkable given the almost 200 years that have passed since these villages were first settled.High German was taught in the local schools until it became unpopular during the period of the first and second world wars.
