[.ca] Danish: A Comprehensive Grammar (ISBN 0415082064)

the joy of Danish grammar...:
This is an excellent (and probably only) English-language guide to thorough Danish grammar. Very refined grammatical points are exemplified and explained in terms that even a non-linguist can understand. This thick book is neatly organized, the material is logically presented, and is hip with contemporary language and usage.

Incredibly important book for serious students of Danish:
If you want to understand the language of Danish -- and Danes are sticklers for grammar, both Danish and English -- then you must have this book or a Danish nun as a teacher. The cross-cultural equivalent of Warriner's English; everything but sentence diagramming. Not quite Strunk & White's Elements of Style, but I need its 600-plus pages. The terminology is "rather" British (see "copulative conjunctions"), yet it even instructs how to properly form colloquial sentences -- "so" colloquial that a Danish friend to whom I had written thought I must have made a mistake because the sentence structure I had used, as a beginner, seemed to arcanely correct. In short, this book is outwardly dull but extremely useful.
