German
Kommazwerg takes reformed German spelling as its standard – i.e., the latest editions of Duden Band 1 and Duden Band 9. Where more than one spelling is possible, Kommazwerg follows Duden’s recommendations, unless otherwise agreed upon. Kommazwerg’s use of end-of-line word division and punctuation conforms to Was Duden empfiehlt and Walter Heuer’s reference work Richtiges Deutsch.
