Learn Danish: Sønnen henter pengene i banken i dag. - The son gets the money at the bank today.

The basic word for "son" is søn. When you add the definite ending -en to make it "the son", the final consonant doubles to keep the vowel sound short. So, søn becomes sønnen.

Can I use får instead of henter to say gets?

Not in this context. The verb at få means "to get" in the sense of receiving something. The verb at hente means "to go get" or "to fetch" something. Since the son is actively going to the bank to pick up the money, you must use henter.

Why does pengene end in -ne? Is money plural in Danish?

Yes! In English, "money" is an uncountable singular noun, but in Danish, penge is a plural word. To say "the money", you add the plural definite ending -ne, making it pengene.

Why do we use i banken instead of på banken?

In Danish, you usually use i when talking about being physically inside a building like a bank or a supermarket. You use på for certain public institutions, like a hospital, or open places.
