Questions & Answers about Han er militær.
Because han is the subject form of the pronoun, and the subject is the one doing or being something in the sentence.
- Han er militær = He is military / He is in the military
- Jeg ser ham = I see him
So in this sentence, han is correct because he is the subject of er.
In Norwegian, after å være, words for profession, role, identity, religion, or nationality often appear without an article.
So Norwegian says:
- Han er lærer
- Hun er student
- Han er militær
not normally:
- Han er en lærer
- Hun er en student
- Han er en militær
This is different from English, where you usually need a or an.
