Chełmno–Dobrzyń dialect

The Chełmno–Dobrzyń dialect (Polish: gwary chełmińsko-dobrzyńskie) belongs to the Greater Poland dialect group and is located in the northern part of Poland. It borders the Bory Tucholskie dialect to the East, the Kociewie dialect to the north, the Kujawy dialect to the south, the Masovian Lubawa dialect to the northeast, and the Near Mazovian dialect to the southeast.

Originally considered by Nitsch to be the oldest subdialect which had significant influence on Pomeranian dialects, Kocevian, Malborsko-lubawski, Warmian, and even Masurian, and even considered a separate supradialect separate from Greater Polish and Masovian, called the Chełmno-Dobrzyń-Kociewie supradialect, the Chełmno-Dobrzyń dialect is now considered to be part of the Greater Polish dialect. This disagreement in classification is likely due to the fact that the Chełmno-Dobrzyń subdialect is a transitionary subdialect, having both Kujavian and Masovian raits. Aside from both Greater Polish and Masovian influence, Chełmno-Dobrzyń has also been affected much by German and somewhat by Russian.
