Silesian or Upper Silesian (Silesian: ślōnskŏ gŏdka, ślůnsko godka, Czech: Slezština, Polish: język śląski/Polish: etnolekt śląski) is a West Slavic lect, related to Polish and Czech. Its vocabulary has been significantly influenced by Central German due to the existence of numerous Silesian German speakers in the area prior to World War II and after, until the 1990s.There is no consensus on whether Silesian is a separate language or a somewhat divergent dialect of Polish.
