Questions & Answers about Vi mødes indenfor i salen, når vejret er for koldt udenfor.

Why is it mødes and not møder in this sentence?

Mødes is the reciprocal (meeting each other), while møder is just meet in a neutral, often one‑way sense.

• Vi mødes i salen = We meet (each other) in the hall.
• Vi møder læreren i salen = We meet the teacher in the hall.

The -s on mødes is related to the passive ending in Danish, but with some verbs (like mødes, skilles, ses) it often has this reciprocal meaning:

• Vi ses = See you / we’ll see each other.
• Vi mødes kl. 8 = We’ll meet (each other) at 8.

Here, Vi møder indenfor i salen would sound more like We happen to meet (someone) inside in the hall, without the clear idea that the people in vi are all meeting each other by arrangement.

Could I say Vi møder hinanden i salen instead of Vi mødes i salen?

Yes, grammatically you can:

• Vi mødes i salen.
• Vi møder hinanden i salen.

Both mean roughly We meet each other in the hall.

Nuance:

• Vi mødes is the most natural and common way to talk about an arranged meeting.
• Vi møder hinanden is correct, but often used more for bumping into each other or simply stating that two people meet. In everyday Danish, people overwhelmingly prefer mødes for planned meetups.

So in this sentence, Vi mødes indenfor i salen sounds more idiomatic than Vi møder hinanden indenfor i salen.
