Wandering across Unilang, I didn't found anything about Fränkisch, or Franconian, a beautiful and lively dialect spoken in central Germany.
As a matter of fact, Franconian has a lot of variants: I will refer here to the one spoken in Franken (Franconia), roughly corresponding to northwestern Bavaria, southern Thuringia and western Hesse and Baden-Württemberg. It is also the area I happen to live in since when I moved from Italy, my home country, so this makes things somewhat simpler.
Franconian has been classified as somewhat in the middle between Central and High German: surely the Franconian-speaking areas around the river Main are more commonly described as "central German" than the ones in Bavaria (and, as a matter of fact, I can also understand Bavarian pretty well) where, especially in Nuremberg, Franconian has absorbed a lot of Bavarian words and forms. Even if Erlangen and Fürth are just 15 km far from each other, for instance, the dialects are pretty different!
I started this topic to answer to some of your question about Franconian (if you have any). Of course we can also discuss it in German, but I used English to attract even beginners or non-German speakers.
