Ostfriesisch
In the eastern Frisian regions, in contrast to North and West Frisia, the Frisian language was replaced by Low Saxon dialects very early. The local dialect is now East Frisian Low Saxon. Though not a Frisian language by linguistic classification, the language is a Friso-Saxon dialect of the Low Saxon language which they call "East Frisian" ("Oostfreesk"), and has major influences in vocabulary and grammar from the original East Frisian language. The only surviving dialect of the East Frisian language is the Saterlandic dialect.
