 The placename ending "—weiler" goes back to the Romance word "villare" and means homestead or farm (as a standalone German word, "Weiler" nowadays means “hamlet”).While only a few places with names ending in "—weiler" arose in the early days of Frankish settlement, new foundings – homesteads and little villages – whose names took this ending were being named as late as the 13th century.Nonetheless, Welchweiler might already have arisen by the 7th century as a single homestead.
