Eastern Low Prussian

Eastern Low Prussian (Mundart des Ostgebietes, lit. dialect of the Eastern territory) is a subdialect of Low Prussian that was spoken around Angerburg (now Węgorzewo, Poland), Insterburg (Chernyakhovsk, Russia), Memelland (Klaipėda County, Lithuania), and Tilsit (Sovetsk, Kaliningrad Oblast, Russia) in the eastern territories of East Prussia in the former eastern territories of Germany. Many speakers of this subdialect were Prussian Lithuanians.

Geography
Eastern Low Prussian had borders with Ostsamländisch, Natangian, and Standard German. Lithuanian language was spoken within its area.

Phonology
In difference to varieties to the West, it had no vocalization of /r/. Its alveolar /r/ probably counts among its influences from Lithuanian. Werdersch has an alveolar as well. Like in Werdersch, it has du motst meaning you have to.

Eastern Low Prussian has a greater phonetic affinity to Standard German than Samlandic. The /ai/ of Samlandic is given as /ei/ with long /e/.

It has features common with Nehrungisch. It has major High German influence, a Lithuanian substrate, even numerous words having undergone High German consonant shift. High German influence is, though not exclusively, by Salzburg Protestants.

It has dorx (with the ach-Laut) for High German durch, English through.

Grammar
There was a diminutive ending -l around Gusev, Kaliningrad Oblast (Gumbinnen), explained by Upper German influence.
