Old Prussian
Also known as: Prussian, Prūsiskan
The only substantially attested West Baltic language, spoken in historical Prussia around the Sambia peninsula — today's Kaliningrad Oblast and north-eastern Poland. Extinct since the early 18th century, after the 1709–1711 plague; attested in three 16th-century catechisms and the Elbing vocabulary, with a modern reconstruction movement.
