Learn Danish: Vi stiger på bussen her.

By itself, stiger means to rise, increase, or climb. But when you add the preposition på, it creates the phrase stiger på, which is the standard way to say getting on or boarding a vehicle in Danish.

How do I say the opposite, like getting off the bus?

You just change the preposition from på to af. To say we get off the bus, you would use the phrase Vi stiger af bussen.

Is there a difference between stiger på bussen and tager bussen?

Yes. Vi stiger på bussen describes the actual physical action of stepping onto the bus. Vi tager bussen means we take the bus, focusing on your choice of transportation rather than the physical action of boarding it.

Can I put her at the beginning of the sentence?

Yes, but you must remember the V2 rule, which means the verb is always the second idea in a statement. If you start with her, you have to swap the subject and verb, making it Her stiger vi på bussen.
