It's an interesting argument; however I am a little dissuaded by the fact that half of the support for the claims of similar syntax between Norwegian and English (split infinitives and placing a preposition at the end of a sentence) are generally considered poor grammar in English.

[fusiongyro]

They're considered "poor grammar" for historical reasons (mainly because they're impossible in Latin), not because they are not understood (compare to "I the dog kick" which is ungrammatical in a much more rigorous sense). From a linguistic standpoint what's interesting is what is understood and what isn't, not what is the most proper.

Those protests were popularized by grammarians who learned grammar thru a Latin lens, so, to them, being used to the Latin grammar, this construct in English looked incorrect. From a Germanic language context, though, it's perfectly normal.

They're not poor grammar at all, since grammar is determined by the consensus of the speakers, and they have spoken (so to speak).
