Wasn't about=om?

[Regney]

"Å tenke på" is used when discussing the (thinking) process going on in your head, e.g.,
Jeg tenker på brannmen hele dagen.

"Å tenke om" is used regarding an opinion, e.g.,
Hva tenker du om brannmenn?
Jeg synes de er kjekke.

[Adam204793]

would't you use tror in that case? to express an opinion? since tror is used for belief? so wouldn't it be A tror om?

[Bunchybunc]

Yes, this is confusing!

[Gavin376056]

same here

Why isn't it "alle" dag, ??

[Erin396857]

hele = all/whole, every part included
alle = every single one of whatever is being counted.
When you say 'all day', you mean the whole day or all the parts of the day.
If you use "alle" you would be referring to all the days but would have to say 'alle dager'.

Not in a creepy way... Riiight?

[MaryRose1]

Fordi de er heite!

[LorannaB]

why is it "hele dagen" and not "hele dag"?
Is it because "hele" requires the definite form?
