Rainer Langenhan of Handakte WebLAWg pointed out this weblog, Sprachblog – Tipps zu deutscher Rechtschreibung und Grammatik. It is part of the site of Ines Balcik, co-author of a book on the subject, Pons Deutsche Grammatik und Rechtschreibung. The book appears to be partly directed at schoolchildren and written with a minimum of jargon and everyday examples. The author is a ‘Diplom-Fachsprachenexpertin’.
The weblog is very new and intended for non-linguists but to people who need to use language at work but have no time for thick books and don’t understand jargon terms. I gather from the comments on January 6th that it’s also not intended for all webloggers – and probably not for me.
Incidentally, I wish Germans wouldn’t always call the accusative the fourth case. It makes life very hard for those of us who learnt it as the second case. Obviously, they have no choice, since in German that’s correct, but I will continue to complain.
