Wenedyk (in English: Venedic) is a constructed language of the naturalistic kind, created by the Dutch translator Jan van Steenbergen. Officially, Wenedyk is a descendent of Vulgar Latin with a strong Slavic admixture, based on the premise that the Roman Empire incorporated the ancestors of the Poles in their territory. Unofficially, it just tries to show what Polish would have looked like if it had been a Romance instead of a Slavic language.
The idea for the language was inspired by such languages as Brithenig, Breathanach and Kerno. The language itself is based entirely on (Vulgar) Latin and Polish: all phonological, morphological, and syntactic changes that made Polish develop from Common Slavic are applied to Vulgar Latin.
