Learn Danish: Hun bor stadig i København. - She still lives in Copenhagen.

In Danish main clauses, adverbs like stadig (still) usually go right after the main verb. So instead of saying "She still lives" like in English, Danish says "She lives still" (Hun bor stadig).

I know the verb at leve means "to live". Why is it bor here?

Danish has two different words for "live". You use at bo when talking about residing somewhere or having a home. You use at leve when talking about being alive or experiencing life. Since she resides in Copenhagen, we use bor.

Could I use endnu instead of stadig to mean "still"?

Yes, you can say Hun bor endnu i København, but stadig is much more common for positive statements. Endnu is mostly used in negative sentences to mean "yet," like in ikke endnu (not yet).

Why do we use the preposition i for Copenhagen?

You almost always use i (in) before the names of cities and countries in Danish. The tricky part for learners is that Danish often uses på (on) for islands, but even though Copenhagen is located on an island, you still use i because it is a city.
