For an Irish person, this sentence is quite amusing as ‘gick’ is slang for ‘poo’!
What's the whole infinite for "gikk"? is it gå?
Yes, it is "gå".
The whole infinitive is "å gå".
Is the Norwegian sentence saying that she walked to the toilet or that she used the toilet or both? I'm asking because in American English, "she went to the bathroom" is used both ways.
I think it can be used in both ways, I think I use it like that (I live in Norway).
If you want to indicate that she went to the bathroom/ restroom without indicating that she used the toilet you could say, "Hun dro på toalettet."
How to know when to say på and when to say til? Is there a rule to this?
"på" is used with this meaning in idioms like "go to school" or "go to the toilet" and alongside "gå" (I can't think of any exception) .
Why do people dislike my comments?? :O
My extended family in Norway always used the phrase "Jeg må på du" (or do; I'm not sure of the spelling.) Is this slang?
My extended family in Norway always said "Jeg må på du" (or do; Im not sure of the spelling.) Is du rather than toalett slang?
My Norwegian teacher says the same.
