Tom vet vad som pågår.

English Translation

Tom knows what’s happening.

‘pågår’ also translates as ‘ongoing’, as in persisting or in progress. “A war BROKE OUT in Africa” is not the same as “A war is ongoing in Africa.” Is there a better translation for “broke out” like, bröt ut?

“Det utbröt ett krig i Afrika” is perhaps the most idiomatic translation, but you can also use “bröt ut”.
