Slovincian

The Slovincian language became extinct in the 20th century. It was one of the Lekhitic languages. Its users lived in parishes of Schmolsin and Garde in Pomerania in present-day Poland. Slovincian was so closely related to Kashubian that it must be regarded as its dialect, but it is conventionally treated separately. Slovincians regarded themseves as Kashubs-Lutherans and their language as Kashubian.
