The current German name of "Bodensee" derives from the place name Bodman, which probably originally derived from the Old High German "bodamon" which meant "on the soils", indicating a place on level terrain by the lake. This place, situated at the west end of Lake Überlingen ("Überlinger See"), had a more supraregional character for a certain period in the early Middle Ages as a Frankish imperial palace ("Königspfalz"), Alamannian ducal seat and mint, which is why the name may have been transferred to the lake ("lake, by which Bodman is situated" = "Bodmansee"). From 833/834 AD, in Latin sources, the name appears in its Latinised form "lacus potamicus". Therefore, the name actually derived from the Bodman "Pfalz" (Latinized as "Potamum") was wrongly assumed by monastic scholars like Walahfrid Strabo to be derived from the Greek word "potamos" for "river" and meant "river lake". They may also have been influenced by the fact that the Rhine flowed through the lake.
