The Northern Ukrainian dialects (), also called the Polesian dialects (), are one of the three main dialect groups of the Ukrainian language, along with Southeastern and Southwestern. Northern Ukrainian is a transitional dialect to the Belarusian language, which is located to the north.
A defining characteristic of the Northern dialects is archaic vocalism of stressed vowels, or, in the case of letters "" and "", the usage of monopthongs when stressed. The letter "" also acquires a sound similar to standard Ukrainian "" when not stressed and preceded by a palatised consonant.
The northern dialects share a simplified morphology with the Southeastern dialects, which they played a critical role in forming. Some more northwestern dialects, located in Podlachia, however, lack this simplified morphology.
In contrast to the Southeastern dialects, which form Ukrainian's literary standard within Ukraine, and the Southwestern dialects, which are the literary standard of the Ukrainian diaspora, the Northern dialects are much less frequent in Ukrainian culture. Lesya Ukrainka's play The Forest Song is one of the most significant works in the Northern dialects.
The Northern dialects are composed of three different dialects: the Western Polesian dialect, the Central Polesian dialect, and the Eastern Polesian dialect. Western Polesian transitions into the Southwestern dialects in the south, while Central and Eastern Polesian are separated by the Dnieper river.
Northern Ukrainian dialects are distinguished from Southeastern and Southwestern Ukrainian dialects by following features:
Different varieties of the Northern group are distinguished by their own specific dialectisms. For example in Western (Volhynian) Polesian the words üþÃÂóÃÂýâÂÂð (morochnya), ÃÂÃÂýñûð (stubla), ÃÂáúòð (chakva), ÃÂûðýâ (tlan') are used in the meaning of "bog"; corresponding words in Central Polesian varieties are ÷âÂÂôâÂÂòâÂÂÃÂö (zdvizh), ÃÂÃÂòâÂÂÃÂóð (stviha), ôÃÂðóá (drahá), and in Eastern Polesian - ÃÂóÿúðùõ ñðûóÃÂð (topkaye balota).
