Peter Olsen Groth, A Danish and Dano-Norwegian Grammar (1894)
“ Thus it is that we have at the present time two kinds of Danish language, the pure Danish used in Denmark and by Danish authors, and the Dano-Norwegian used in Norway by most of the educated classes, especially in the cities, and by most of the Norwegian authors. Still it should be noted that the language spoken in Norway even by educated people is far more national in its character than the one used in writing. ”
