Learn Swedish: Vi befinner oss i en svår situation. - We find ourselves in a difficult situation.

While Vi är... (We are...) is grammatically correct and works perfectly well, befinner oss sounds slightly more formal and descriptive. It emphasizes the state or location you are currently placed in, much like the English phrase "we find ourselves in".

Is the verb befinna always used with a reflexive pronoun like oss?

Yes, in modern Swedish, this verb is almost exclusively used as the reflexive verb befinna sig. Depending on the subject, you must change the pronoun to match: jag befinner mig, du befinner dig, vi befinner oss, and so on. Without the reflexive pronoun, the sentence is grammatically incomplete.

Could I use hård instead of svår to mean a "hard" situation?

Not naturally. In Swedish, hård is generally used for physical hardness (like a rock) or strictness (like a harsh punishment). For something that is complicated, problematic, or mentally taxing, svår is the natural choice. You could also use jobbig to emphasize that the situation is emotionally draining.

How can I remember whether words like situation are en or ett words?
