It is one of two parallel mountain ridges of the Eastern Beskids, situated in western parts of modern Ukraine.
They are stretching parallel to the Wooded Beskids on the northeast, and Vihorlat-Gutin Area to the southwest.
[1] The name of this mountain range is derived from Slavic term polonyna, designating a particular type of montane meadows, characteristic for those parts of the Carpathians.
In Polish and Ukrainian terminology, this range is most commonly called the "Polonynian Beskids" (Ukrainian: Полонинські Бескиди; Polish: Beskidy Połonińskie), while in Slovakia it is also defined in a much wider sense, under the local term Poloniny (Slovak: Poloniny).
The territorial scope of all those terms varies in accordance to different classifications and traditions.
