As far as I know, the following negative construction must be correct: - Snakker du norsk? - Nei, det gjør jeg ikke. And what about this variant of short answer: - Nei, jeg gjør ikke. Is it correct also? For example, the first lines of "Peer Gynt" have a similar thing: Aase: Peer, du lyver! Peer Gynt (uden at standse): Nej, jeg gør ej! Will the latter phrase be 'Nei, jeg gjør ikke' in current Norwegian bokmål?
