Mobilbetalingen virker.

Because Norwegian very often forms compound nouns as a single word, where English would often use two words.

So:

• mobil = mobile / mobile phone
• betaling = payment
• mobilbetaling = mobile payment
• mobilbetalingen = the mobile payment

Writing it as mobil betalingen would be wrong in standard Norwegian.

The ending -en marks the noun as definite singular: the mobile payment.

A useful breakdown is:

• en betaling = a payment
• betalingen = the payment
• en mobilbetaling = a mobile payment
• mobilbetalingen = the mobile payment

In Norwegian, the definite article is usually attached to the end of the noun instead of appearing as a separate word like English the.

Yes, betaling is normally treated as a masculine noun:

• en betaling
• betalingen

In Bokmål, many feminine nouns can also be used as masculine, but betaling is commonly learned as masculine. That is why you see -en in the definite singular.

Because in Norwegian, the noun itself often carries the meaning of the through its ending.

Compare:

• English: the mobile payment
• Norwegian: mobilbetalingen

The -en already gives the definite meaning, so no separate the is needed here.

Here, virker means something like:

• works
• is working
• functions

It comes from the verb å virke.

So in everyday usage, virker is often used for something that is operating properly:

• Internett virker. = The internet works.
• Kortet virker ikke. = The card doesn’t work.

Yes, often you could. Both virker and fungerer can mean works / functions.

For example:

• Mobilbetalingen virker.
• Mobilbetalingen fungerer.

Both are natural.
However, virker is extremely common in everyday speech when talking about whether something works.

Very roughly:

• virker = works
• fungerer = functions

In many contexts, they are interchangeable.

Norwegian main clauses usually follow the V2 rule: the finite verb comes in the second position.

In this sentence:

• Mobilbetalingen = first element
• virker = second element

So the structure is completely normal:

• Mobilbetalingen virker.

This is similar to standard English word order in a simple sentence, but the V2 rule becomes especially important in other Norwegian sentence patterns too.

The infinitive is å virke.

A few useful forms:

• å virke = to work / to function
• virker = works / is working
• virket = worked
• har virket = has worked

So virker is the present tense form.

You would use the plural form:

• mobilbetalinger = mobile payments
• mobilbetalingene = the mobile payments

So:

• Mobilbetalinger virker. = Mobile payments work.
• Mobilbetalingene virker. = The mobile payments work.

Singular and plural are important to watch in Norwegian compounds, because the endings change just like they do with simple nouns.

A helpful learner-friendly guide is:

• mobilbetalingen ≈ moh-BEEL-beh-TAH-ling-en

A few tips:

• mobil has stress on the last syllable: mo-BIL
• betaling has stress on ta: be-TA-ling
• in the full compound, the strongest stress is usually around -ta- in betaling

Norwegian pronunciation varies a bit by dialect, but this is a good general starting point.

Yes, depending on context, it can refer to either:

• a payment made by mobile phone
• mobile payment as a payment method or system

That is normal in Norwegian compounds. Context usually makes the intended meaning clear.

So Mobilbetalingen virker could mean something like:

• the mobile payment went through successfully
• the mobile payment system is working

Both are possible depending on the situation.

Because Norwegian compounds do not insert articles inside the compound. The first part simply modifies the second noun.

So:

• mobil
  • betaling = mobilbetaling

This works much like English compounds such as:

• card payment
• cash machine
• phone bill

Norwegian just tends to write these combinations as one word much more consistently.
