I know it was already discussed before but could you please clarify one more time when to use the indefinite article with proffesions and when not. I know that one must use it if there is an adjective with the proffesion. When else?
I'm not a native speaker (I'm at exactly this level), but all I remember is you can say "jeg er ingeniør", but if you want to say you aren't one, you have to use the article. Jeg er ikke en ingeniør.
There's another case or two that I can't remember though.
