Questions & Answers about Vem som än ringer mig under mötet, svarar jag inte.
It means whoever or no matter who.
So Vem som än ringer mig under mötet means something like whoever calls me during the meeting / no matter who calls me during the meeting.
This is a common Swedish pattern for expressing it doesn’t matter who / what / where / when.
In this construction, Swedish normally uses the pattern:
question word + som + än
So:
- vem som än = whoever
- vad som än = whatever
- var som än = wherever
- när som än = whenever
Here, som is part of the fixed structure, and än adds the sense of no matter / ever.
So you should learn vem som än as a unit.
