Learn Swedish: Köper du väskan? - Are you buying the bag?

Köper is the present tense form. In Swedish, regular Group 2 verbs drop the final -a from their dictionary form (köpa) and add -er to make the present tense. So köpa becomes köper (buy, buys, or am buying).

Why does the sentence start with the verb köper?

To ask a yes/no question in Swedish, you put the verb first. The statement form is Du köper väskan (You are buying the bag). By swapping the subject (du) and the verb (köper), it becomes the question Köper du väskan? Swedish doesn't use helping words like are or do to ask questions.

Why does the word for bag end with an n (väskan)?

The basic word for a bag is en väska. Swedish doesn't use a separate word for the English word the. Instead, you attach the article to the end of the noun. Because väska is an en-word that already ends in a vowel, you just add -n to the end to mean the bag: väskan.

Does the k in köper sound like a hard English k?

No, it sounds more like the sh in shoe (or a soft ch sound, depending on the region). In Swedish, when k comes before a soft vowel like ö, it changes from a hard k to this soft sound.
