Wenedyk
Wenedyk (in English: Venedic) is a made-up language. Jan van Steenbergen, a linguist and translator from the Netherlands, made it in 2002. The idea behind it is this: what would have happened if the Polish language had developed from Latin instead of Old Slavic? Wenedyk is a possible answer to that question. It is a Romance language, so almost all words are family of words in French, Italian, Romanian, and so on. But they look very different and much more like Polish. The rules for spelling and pronunciation are completely based on Polish. Other parts of the language, like grammar and sentence structure, are a mixture of Polish and Romance.
