"The question is difficult to answer."
Translation:Frågan är svår att svara på.
Another way to say this is that an intransitive or prepositional verb often has a transitive counterpart that starts with the prefix be. German and Dutch are like this, too.
In fact, English has this, too, although the verbs that do this tend to sound old or formal. Consider to belittle (to make little), to bewitch (to enchant) and to bemoan (to moan about). It's even there in adjectives formed from old past participles, like bespectacled.
