Learn Swedish: Vem hämtar väskan? - Who is fetching the bag?

In Swedish, yes/no questions start with the verb. But when you use a question word like vem (who), that word takes the first spot. Because Swedish loves to keep the verb in the second position (this is called the V2 rule), the verb hämtar comes immediately after it.

The English translation says "is fetching", but isn't hämtar just "fetches"?

It means both! Swedish doesn't have a separate "-ing" form (continuous tense) like English does. Vem hämtar translates to "Who fetches", "Who does fetch", or "Who is fetching" depending on what sounds best in English.

Why does the word for bag end in "-n" (väskan)?

That -n at the end is how Swedish says "the". The basic word for "a bag" is en väska. For en-words that end in a vowel like -a, you just add an -n to the end to make it "the bag" (väskan).

Can hämtar also mean "picking up" someone or something?

Yes! Hämtar is a very common and useful verb for fetching, getting, bringing, or picking up. You can use it for picking up a bag (väskan), grabbing a coffee, or picking a friend up from the airport.
