Pomeranian is a group of Lekhiticdialects, sometimes called also the dialects of Polish. In the Middle Ages these dialects were spoken in all territory of Pomerania. According to Florian Ceynowa, today the only living descendand of Lekhitic Pomeranian is Kashubian language spoken in Eastern Pomerania (Pomeranian Voivodship). A dialect of Kashubian language, Slovincian became extinct around 1945. Other dialects used by autochtonic people of Pomerania (Kociewiacy, Borowiacy, Krajniacy) were influenced by Pomeranian/Kashubian, however are considered parts of Great Polish dialect (Krajniacy) and Masurian dialect (Kociewiacy).
Pomeranian (German Pommersch) is an East Low Germandialect. It is the language of the German Pomeranians in western Pomerania, which today is included in the Bundesland of Germany called Mecklenburg-Vorpommern. It is a form of East Low German with Slavic influence.
The Pomeranian language, and its only surviving form, Kashubian, traditionally haven't been recognized by the majority of Polish linguists and have been treated in Poland as "the most distinct dialect of Polish".
The bill passed by the Polish parliament in 2005 recognizes Kashubian as the only regional language in the Republic of Poland and provides for its use in official contexts in 10 communes where Kashubian speakers constitute at least 20 percent of the population.
Pommersch Platt is the dialect of the German Pomeranians (Pommern) in western Pomerania, which today is included in the Bundesland of Germany called Mecklenburg-Vorpommern.
