Learn Danish: Hvem kommer fra lufthavnen? - Who is coming from the airport?

The preposition fra means "from" and shows the starting point of a movement. Because the person is leaving the airport, we use fra. If they were traveling to the airport, you would use til instead: Hvem kommer til lufthavnen? (Who is coming to the airport?).

Does kommer translate to "comes" or "is coming"?

It translates to both! Danish does not have a separate "-ing" tense like English does. The present tense verb kommer can mean "comes" or "is coming" depending on the context. In this sentence, "is coming" makes the most sense in English.

Why does the word for airport end in -en here?

In Danish, you make a noun specific (meaning "the") by attaching the article to the end of the word. The basic word is en lufthavn (an airport). By adding -en to the end, it becomes lufthavnen, which means "the airport".

Is lufthavn made up of smaller words?

Yes, it is a compound word exactly like its English translation. It is made of luft (air) and havn (port or harbor).
