In Germany, we say 'Trenne nie st, denn es tut ihm weh.' Never divide between 'S' and 'T,' because that hurts!

Well, at least we said so until the German spelling reform – since then, most people have been confused about the rules. Good to know that the Duden’s corrector software knows it all. It corrects mistakes and makes you have that light bulb moment. And so do the radio spots.

They deal with the boring topic of division and hyphenation in a witty way and they make it impressively clear that dividing can hurt a lot. Here, an expert is needed to make it stop - and the Duden’s correction software truly is an expert.
