Dyrlegen kontrollerer vekten.

Because -en is the definite article for many masculine nouns in Norwegian.
Dyrlege means veterinarian / vet, and dyrlegen means the veterinarian.

This is different from English, where the is a separate word. In Norwegian, the definiteness is often attached to the noun itself.

• en dyrlege = a veterinarian
• dyrlegen = the veterinarian

It is a compound noun:

• dyr = animal
• lege = doctor

So dyrlege literally means animal doctor, which is the normal Norwegian word for veterinarian / vet.

Compound nouns are very common in Norwegian.

For the same reason: vekten is the definite form of vekt.

• en vekt can mean a weight or a scale, depending on context
• vekten = the weight

In this sentence, vekten means the weight, not the scale.

So the pattern is:

• vekt = weight
• vekten = the weight

Because Norwegian often puts the at the end of the noun instead of using a separate article before it.

So English:

• the veterinarian
• the weight

becomes Norwegian:

• dyrlegen
• vekten

This is one of the first big structural differences English speakers notice.

Kontrollerer is the present tense of kontrollere.

• å kontrollere = to check / inspect / monitor
• kontrollerer = checks / is checking

A very common present-tense pattern in Norwegian is:

• infinitive: -e
• present tense: -er

So:

• å snakke → snakker
• å kontrollere → kontrollerer

No. In Norwegian, verbs usually do not change for different persons the way they do in English.

So you get:

• jeg kontrollerer = I check
• du kontrollerer = you check
• han/hun kontrollerer = he/she checks
• vi kontrollerer = we check

The form kontrollerer stays the same.

Not exactly. This is an important nuance.

In Norwegian, kontrollere often means:

• check
• inspect
• verify
• monitor

It does not always mean control in the English sense of directing or being in charge of something.

So in Dyrlegen kontrollerer vekten, the most natural sense is that the vet is checking or monitoring the weight.

The word order is the basic Norwegian pattern:

Subject + Verb + Object

• Dyrlegen = subject
• kontrollerer = verb
• vekten = object

So it works very much like English here:

• The veterinarian checks the weight

This sentence is straightforward and uses normal main-clause word order.

Usually no, not in normal natural Norwegian for this meaning.

You would normally need articles/definite marking:

• en dyrlege = a veterinarian
• dyrlegen = the veterinarian
• en vekt = a weight
• vekten = the weight

So dyrlege kontrollerer vekt sounds incomplete or unnatural in most ordinary contexts.

The full sentence Dyrlegen kontrollerer vekten is natural because both nouns are in their definite forms.

A simple learner-friendly approximation is:

DEER-leh-ghen kon-troh-LEH-rer VEK-ten

A few notes:

• y in dyr is not like normal English ee or i. It is a rounded vowel that many learners need time to master.
• g in lege is often softened in normal speech.
• The r in Norwegian varies by dialect, so don’t worry if yours does not sound perfect yet.

If you want a practical goal as a beginner, focus on getting the stress roughly right:

• DYR-legen
• kontrolLErer
• VEKTen

Yes. Norwegian present tense often covers both:

• checks
• is checking

So kontrollerer can mean either, depending on context.

Without extra context, Dyrlegen kontrollerer vekten could be understood as:

• The veterinarian checks the weight
• The veterinarian is checking the weight

Both are possible.
