It is assumed that it evolved from the language spoken by some tribes of Pomeranians called Kashubians, in the region of Pomerania on the southern coast of the Baltic Sea between the Vistula and Oder rivers.
As of 2000, it had some 200,000 speakers, mainly in eastern Pomerania in northern Poland. In 2002 Census, 53,000 people in Poland declared that they mainly use Kashubian at home. Research shows that many Kashubian-speaking parents use Polish rather than Kashubian at home, because they believe that if they spoke Kashubian, their children would find it more difficult to learn correct Polish.
The dialects spoken by other ethnic groups are between Kashublanguage and Polish dialects of Great Poland and Mazovia.
The parliament (Landtag) of Prussia in KÃÂönigsberg in 1843 decided to change the official church language from Polish to German, but this decision was soon recalled and starting in 1852 Kashubianlanguage was taught at the Gymnasium (high school) of Wejherowo.
Scientific interest in the Kashubianlanguage was sparked by Mrongovius (publications in 1823, 1828) and the Russian linguist Hilferding (1859, 1862), later followed by Biskupski (1883, 1891), Bronisch (1896, 1898), Mikkola (1897), Nitsch (1903).
Kashubian or Cassubian (Kashubian: kaszëbsczi jãzëk, pòmòrsczi jãzëk, kaszëbskò-słowińskô mòwa) is one of the Lechitic languages, which are a group of Slaviclanguages.
It is assumed that it evolved from the language spoken by some tribes of Pomeranians called Kashubians, in the region of Pomerania on the southern coast of the Baltic Sea between the Vistula and Oder rivers.
A number of schools in Poland teach in Kashubian as a lecture language and it is used as an official alternative language for local administration purposes in parts of Pomorze Voivodship.
