The West Polesian language (Belarusian: Заходнепалеская мікрамова, Zakhodniepalieskaya mikramova; Ukrainian: Західнополіська мікромова, Zakhidnopolis'ka mikromova) or dialect is spoken in Southeastern Belarus, in Northwestern Ukraine and in the bordering regions of Poland. It is also considered as one of the Slavic microlanguages, in effect a transitional language between the Ukrainian and the Belarusian.
West Polesian is mostly used in everyday speech, though attempts have been made in 1990s to develop a standard written language for the dialects.
