[interfixus]

Everything you said. And yes, obviously I'm thinking primarily of Norwegian bokmål. Although I do comprehend at least som spoken fjeldnorsk. Having had a Faroese girlfriend, and some exposure to Icelandic does help :)

Rhythm and intonation of spoken Danish shifts markedly down towards the southern islands. No difficulty of compehension whatsoever, but it's clearly a dialectal belt with a history quite different from neighbouring parts of Sjælland (or "Zealand"). I'd love to see a genetic mapping of the local communities. I'm almost certain that lots of corresponding patterns would turn up.
