Grammatical reference materials

• Updated grammatical terms for use in the schools (Norsk språkråd):  The grammar sites above use the new grammatical terms.  The biggest changes are the new terms for verb tenses and the creation of a new category–determinatives–that includes articles, possessives, demonstratives, and words expressing quantity.)
• Changes in spelling and grammar from July 1, 2005 (I'm a bit of a grammar geek and never had difficulty learning grammatical forms, but I find it really hard to relearn forms I have known for 25 years whenever a new update to the grammar and spelling rules is released.)
• Rules for writing and grammar
• List of Norwegian equivalents of English words / Quizzes
