In English it's not very clear who is referred as "Bavarian". It can either mean "somebody from Bavaria" or "somebody culturally Bavarian", such as Austrians, South Tirolians and some other smaller language islands.
Not everybody who lives in Bavaria or Austria speaks Bavarian however. In the state of Bavaria there are also Franconians and Swabians. In the state of Austria only some parts speak a different language, mainly in the far west.
On this webpage we will teach you about the Bavarian culture and language. We also have a project to create an unbiased standard for the Bavarian language and you are more than welcome to make your contribution to it!
