Colognian
Kölsch is unusually well documented. Some linguists of the local universities have shown great interest in Kölsch and the ripuarian dialects, and research on them. Outside the world of science, the Akademie för uns Kölsche Sproch (Academy in favour of our Kölsch language) offers regular courses, classes, excursions for everybody. They publish a dictionary, a grammar, and phrase books. It is probably the only institute of its kind worldwide.
