Attesteringen begynner nå.

Because Norwegian usually puts the definite article on the end of the noun instead of using a separate word like the.

• attestering = the basic noun
• attesteringen = the
  • noun

So attesteringen is the definite singular form.

It is built in layers:

• å attestere = the verb
• attestering = a noun made from that verb
• attesteringen = the definite singular form of that noun

This is a very common pattern in Norwegian: verb + -ing to make a noun.

Begynner is the present tense of å begynne.

A useful thing for English speakers: Norwegian verbs do not change for person the way English does. So you get:

• jeg begynner
• du begynner
• han/hun begynner
• de begynner

The verb form stays the same.

Yes. Norwegian often uses the simple present where English might use either the simple present or the present progressive.

So begynner nå can match English ideas like:

• begins now
• is beginning now
• is starting now

The word nå makes it clear that this is happening at this moment.

That is a very normal, neutral word order in Norwegian.

The structure is:

• subject: Attesteringen
• verb: begynner
• time adverb: nå

So Attesteringen begynner nå is a straightforward way to say it.

Yes, absolutely. That is also natural.

Putting nå first gives it a little more emphasis, like Now the attestation begins. But when Norwegian puts something first, the finite verb still has to come second. That is why it is:

• Nå begynner attesteringen

and not:

• Nå attesteringen begynner

This is part of the Norwegian verb-second word order rule.

Usually no. It sounds fairly formal or technical. You are more likely to see it in administrative, financial, legal, workplace, or system-interface contexts than in casual everyday conversation.

So the grammar is ordinary, but the noun itself is somewhat specialized.

Often yes. Attesteringen starter nå would also sound natural in many contexts.

The difference is small:

• begynner = begins
• starter = starts

In practice, both can work here, but begynner is a bit more general.

Because Norwegian does not need an extra helping verb here the way English often does in is beginning.

English often uses:

• is beginning
• is starting

But Norwegian usually just uses the present tense form:

• begynner
• starter

So one Norwegian verb form can cover what English expresses with two words.

Yes. It has everything it needs:

• a subject: Attesteringen
• a finite verb: begynner
• a time adverb: nå

So it works perfectly well as a full statement, especially in an announcement, interface message, or formal process description.
