Kan du veksle penger?

• Kan = can / are able to
• du = you
• veksle = exchange / change
• penger = money

So the sentence is literally Can you exchange money? or Can you change money?

Because this is a yes/no question.

In Norwegian, a simple statement would be:

• Du kan veksle penger. = You can exchange money.

To turn that into a question, Norwegian usually switches the order so the verb comes first:

• Kan du veksle penger? = Can you exchange money?

This verb-first pattern is very common in Norwegian questions.

Because kan is a modal verb. After modal verbs in Norwegian, the next verb normally appears in the infinitive without å.

So:

• å veksle = to exchange
• kan veksle = can exchange

The same thing happens with other modal verbs:

• Jeg kan svømme. = I can swim.
• Du må gå. = You must go.

Not kan å veksle.

Because Norwegian usually uses penger as the normal word for money, even though English treats money as singular.

So:

• Jeg har ikke penger. = I don’t have money.
• Hun trenger penger. = She needs money.

The singular penge exists, but in everyday modern Norwegian, penger is the usual word when you mean money in general.

It can mean a couple of closely related things, depending on context:

• exchange money in the currency sense
  
  • for example, changing euros into kroner
• change money in the smaller-notes / coins sense
  
  • for example, breaking a large bill into smaller money

So the phrase is a little broad. If you want to be more specific, Norwegian often adds details:

• Kan du veksle euro til kroner? = Can you exchange euros for kroner?
• Kan du veksle en hundrelapp? = Can you change a 100-kroner note?

Yes, usually.

In Norwegian, Kan du ... ? is a normal and acceptable way to ask someone to do something. It often sounds less blunt than it might in English.

If you want to sound softer or more polite, you could say:

• Kunne du veksle penger? = Could you exchange money?
• Kan du være så snill å veksle penger? = Could you please exchange money?

But Kan du veksle penger? is perfectly natural in many situations.

Yes. In modern Norwegian, du is the normal word for you, even with strangers, staff, older people, and people in formal situations.

The old formal pronoun De does exist, but today it sounds very formal, old-fashioned, or distant in most contexts.

So in normal modern Norwegian:

• Kan du hjelpe meg? = Can you help me?

is completely standard, even to someone you do not know.

Then you would say:

• Kan jeg veksle penger? = Can I exchange money?

This is a useful distinction:

• Kan du veksle penger? = asking whether you can do it
• Kan jeg veksle penger? = asking whether I am allowed / able to exchange money

In real life, if you are at a bank or exchange counter, Kan jeg veksle penger her? = Can I exchange money here? may sound especially natural.

A rough pronunciation guide is:

• Kan ≈ kahn
• du ≈ doo (but with a more rounded Norwegian vowel)
• veksle ≈ VEK-sluh
• penger ≈ PENG-er

Very roughly:

kahn doo VEK-sluh PENG-er?

A few notes:

• The stress is mainly on VEK- in veksle and PENG- in penger.
• The g in penger is pronounced.
• The final -e in veksle is a weak vowel sound, like uh.

Yes. The sentence is correct, but in many real situations Norwegian speakers often make it more specific.

Examples:

• Kan du veksle euro til kroner?
  Can you exchange euros for kroner?

• Kan du veksle denne?
  Can you change this?
  (for example, a banknote you are holding)

• Har du vekslepenger?
  Do you have change?

• Kan jeg få vekslet penger?
  Can I get some money exchanged?

So Kan du veksle penger? is grammatical and understandable, but context often decides whether a more specific version sounds better.

The statement version is:

• Du kan veksle penger. = You can exchange money.

This is useful because it shows the normal question pattern clearly:

• Du kan ... = statement
• Kan du ... ? = question

That verb-subject switch is one of the most important patterns in Norwegian.
