Questions & Answers about Han er uvitende om problemet.
Because Norwegian uses å være (to be) with adjectives, just like English does.
- Han er uvitende = He is unaware / ignorant
- Han har uvitende would be ungrammatical
Here, uvitende is describing his state, so er is the correct verb.
Uvitende means unaware, ignorant, or not knowing.
It is built from:
- u- = a negative prefix, like un- in English
- vitende = knowing
So uvitende literally suggests unknowing.
In this sentence, it usually means unaware rather than stupid or foolish. That matters, because English ignorant can sometimes sound insulting, while Norwegian uvitende is often more neutral.
