Ambulansen kom raskt.

In Norwegian, the definite article is usually attached to the end of the noun.

So:

• ambulanse = ambulance
• ambulansen = the ambulance

The ending -en is what makes it definite here. This is very common in Norwegian.

The dictionary form is ambulanse.

So the pattern is:

• en ambulanse = an ambulance
• ambulansen = the ambulance

If you look the word up in a dictionary, you would normally search for ambulanse.

Kom is the past tense of komme.

• komme = infinitive, to come
• kommer = present tense, comes / is coming
• kom = past tense, came

So Ambulansen kom raskt uses the simple past.

Yes. The verb komme is irregular.

You cannot make the past tense by adding a regular ending in a simple way. You just have to learn:

• komme
• kommer
• kom
• har kommet

This is a very common verb, so it is worth memorizing early.

No. Norwegian verbs do not change for person or number the way English verbs do.

For example:

• jeg kommer = I come / I am coming
• du kommer = you come / are coming
• ambulansen kommer = the ambulance comes / is coming

The verb form stays kommer in all of those. The same is true in the past tense:

• jeg kom
• du kom
• ambulansen kom

So Norwegian verb conjugation is simpler than English in that way.

Because raskt is being used adverbially: it describes how the ambulance came.

• rask = quick, usually an adjective
• raskt = quickly / fast, used to describe the action

In this sentence, raskt tells us something about the verb kom, so raskt is the natural form.

A useful way to think about it is:

• adjective: en rask bil = a fast car
• adverb: Bilen kjører raskt = The car drives fast / quickly

Yes. In Ambulansen kom raskt, raskt functions as an adverb.

It does not describe the noun ambulansen. It describes the action kom.

So it answers the question How did it come?
Answer: raskt.

Yes. This is the normal, neutral word order for a simple statement:

• Ambulansen = subject
• kom = finite verb
• raskt = adverb

So the pattern is basically:

Subject + verb + adverb

This is the most natural order in an ordinary main clause like this.

Usually, in a simple sentence like this, after the verb is the most natural place.

So:

• Ambulansen kom raskt. = normal and natural

You may sometimes see other orders for emphasis or in more literary style, but for everyday learning, this is the safest pattern to use.

Yes. Fort is also very common and natural.

Both of these work:

• Ambulansen kom raskt
• Ambulansen kom fort

In many everyday situations, fort may sound a bit more conversational. Raskt is also correct and natural, just slightly more neutral or formal in feel depending on context.

A rough guide is:

• Ambulansen ≈ am-boo-LAHN-sen
• kom ≈ kohm
• raskt ≈ rahskt

Approximate IPA:

• Ambulansen: [ambuˈlɑnsən]
• kom: [kɔm]
• raskt: [rɑskt]

The main stress in ambulansen falls on -lan-.
