Silesian, occasionally called Upper Silesian, is an ethnolect of the Lechitic group spoken by part of people in Upper Silesia. Its vocabulary was significantly influenced by Central German due to the existence of numerous Silesian German speakers in the area prior to World War II and after. The first mentions of Silesian as a distinct lect date back to the 16th century, and the first literature with Silesian characteristics to the 17th century.
