The Pomeranian language (Polish: pomorszczyzna or język pomorski, German: Pomoranisch or die pomoranische Sprache) is in the Pomeranian group of Lechitic languages (Polish: grupa pomorska języków lechickich, German: die pomoranische Gruppe der lechischen Sprachen) within the West Slavic languages. In medieval contexts, it refers to the dialects spoken by the Slavic Pomeranians. In modern contexts, the term is sometimes used synonymously with "Kashubian" and may also include extinct Slovincian. The name Pomerania comes from Slavic , which means "[land] by the sea". Ancient Pomeranian During the early medieval Slavic migrations, the area between the Oder and Vistula rivers was settled by tribes grouped as Pomeranians. Their dialects, sometimes referred to as Ancient Pomeranian, had a transitory character between the Polabian dialects spoken west of Pomerania and the Old Polish dialects spoken to the southeast. While there are no surviving documents in Pomeranian, medieval Pomeranian names are mentioned in contemporary documents written in other languages. Slovincian and Kashubian During the High Middle Ages, German immigration and assimilation of the Slavic Pomeranians () introduced Low German East Pomeranian, Central Pomeranian, and dialects, which became dominant in Pomerania except for some areas in the east, where the populace remained largely Slavic and continued to use the Slavic Pomeranian language. This was especially the case in Pomerelia, where the Slavic population became known as Kashubians and their language accordingly as Kashubian. An insular Slavic Pomeranian dialect spoken northwest of Kashubia until the 20th century became known as Slovincian. It is disputed whether Slovincian may be regarded as a dialect of Kashubian or a separate language. Likewise, it is disputed whether Kashubian may be regarded as a dialect of Polish or a separate language. Stefan Ramułt (1859–1913) was fascinated by Florian Ceynowa and decidedly supported giving Kashubian the status of a full-fledged standard language. Influence on other dialects The Pomeranian language influenced the formation of other Polish language dialects, such as the Kociewski, Borowiacki and Krajniacki dialects. Undoubtedly, they belong to the Polish language, but they also have some features in common with the Pomeranian language, which proves their character was transitional. Friedrich Lorentz supposed that the Kociewski and Borewiacki dialects first belonged to the Pomeranian language and were then Polonized as a result of the Polish colonization of these territories. According to Lorentz, the Krajniacki dialect most probably was originally a part of the Polish language. The common feature of the Kociewski dialects and
