Bergish is the collection of local speech varieties of the Bergisches Land Region east of the Rhine in West Germany. The term is common in the general populace, but is not of much linguistic relevance, because the varieties belong to several quite distinct groups inside the Continental West Germanic dialect continuum. As usual inside a dialect continuum, neighboring varieties have a maximum of similarities, and speakers being used to the rather small individual lingual differences in their immediate neighborhood perceive them naïvely as varieties of some bigger, undivided group, such as "Bergish", being part of "Rhinelandic", being part of "German", etc..
In fact, "Bergish" varieites belong to three major groups following the dialect geographers of today:
The Bergish varieties in the northern areas are also referred to as parts of Meuse-Rhenish, which exclusively refers to the Low Franconian varieties, that are Limburgish including Low Bergish, and Zuid-Gelders including East Bergish.
