Based on the replies in this thread, I think you're looking for "at spørge om noget". "Jeg vil gerne spørge om noget." - " I would like to ask about something". "Jeg spurgte om de kom" - "I asked if they were coming".
Is this the one?
Right, and that is the translation for this exercise, but I wish to know how to say "ask about something". I can "ask about leprosy" without "asking for leprosy".
Sorry, I could have been clearer.
I can ask about leprosy, in that I am curious about what this disease is, how common it is, etc, but I wouldn't ask for leprosy, because that means I want to have the disease.
So we know that "bede om noget" = "ask for something", but I would like to know the left hand side of the equality ? = "ask about something".
I guess it can mean both things since the word om means actually in most cases "about". But maybe a native speaker could clarify this for you :p
