Jatwingisch (also Sudauisch , jatw. Jātviun / sūdaviun bilā ) was a western Baltic language of the Jatwingers ( Balts ), a tribe related to the Prussians between the Vistula and Memel ( Baltic States ). After the conquest of the area by the Teutonic Knights , it died out, the Yatwingers gradually merged into the German, Lithuanian (East Baltic) and Slavic element.
Jatwingisch had six cases ( nominative , genitive , dative , accusative , locative and vocative ) and a complex verbal morphology with different modes . It was one of the marginal dialects of the Ur-Baltic, which is why it retained many archaic features that were lost in the Central Baltic region.
There are many Yatvian loanwords in the Belarusian dialects . Written language certificates are not known, except for a short dictionary, which is controversial.
