No argument. My point was that a great many languages have dialects, yet are still recognized as a lanugage.That would have been "hochdeutsch". But no one in germany speaks hochdeutsch. Its basically only for formal letters so that everyone can communicate with eachother.
Apart from school or work everyone uses the local dialect.
This is why so many people who learned german in school outside of germany/austria/switzerland are really puzzled when they get to germany and dont understand anything.
German dialects - Wikipedia, the free encyclopedia
Quite a good map.
There are quite a few videos on youtube about this but they are all on german.
One wouldn't argue that there is no "Chinese", simply because Guan Dong Hua sounds different from Beijing Hua.
(Characters are the same though.)
