Juryen velger vinneren.

Because -en is the usual definite singular ending for many common-gender nouns in Norwegian.

• jury = jury
• juryen = the jury

and

• vinner = winner
• vinneren = the winner

So the sentence uses two definite nouns: the jury and the winner.

In Norwegian, the definite article is often attached to the end of the noun instead of appearing as a separate word before it.

So instead of saying something like the jury, Norwegian commonly says:

• juryen = the jury
• vinneren = the winner

This is one of the big differences from English. English usually puts the before the noun, but Norwegian often puts definiteness at the end of the noun.

Velger is the present tense of the verb å velge, which means to choose or to select.

So:

• å velge = to choose
• velger = chooses / is choosing

In this sentence, velger means chooses.

Because Norwegian verbs are much simpler than English verbs in this way. In the present tense, the verb usually has the same form for all subjects.

For å velge:

• jeg velger = I choose
• du velger = you choose
• han/hun velger = he/she chooses
• vi velger = we choose
• de velger = they choose

So unlike English, Norwegian does not add a special -s form only for he/she/it.

Yes. This sentence has standard subject–verb–object order:

• Juryen = subject
• velger = verb
• vinneren = object

So it is a straightforward main clause:

The jury chooses the winner.

This is the most basic Norwegian word order in a simple statement.

Because jury is treated as a singular collective noun. It refers to a group, but grammatically it is one unit.

So Norwegian uses singular agreement here:

• Juryen velger ... = The jury chooses ...

This is similar to English, where the jury can also be treated as a single body.

Yes. Å velge can mean:

• choose
• select
• sometimes elect, depending on context

In this sentence, choose or select is the most natural meaning.

The difference is indefinite vs definite:

• vinner = a winner / winner
• vinneren = the winner

So:

• Juryen velger en vinner = The jury chooses a winner
• Juryen velger vinneren = The jury chooses the winner

The second version sounds as if the winner is already understood as a specific person or role in the context.

Because en and -en do different jobs.

• en vinner = a winner
• vinneren = the winner

You do not combine them in a simple phrase like this. So en vinneren would be wrong.

The noun is either:

• indefinite: en vinner or
• definite: vinneren

Because jury is normally treated as a common-gender noun in Norwegian. Common-gender nouns usually take:

• en in the indefinite singular
• -en in the definite singular

So the pattern is:

• en jury = a jury
• juryen = the jury

Likewise:

• en vinner = a winner
• vinneren = the winner

A rough guide for an English speaker is:

• juryen ≈ YOO-ree-en
• velger ≈ VEL-ger
• vinneren ≈ VIN-ner-en

A few useful notes:

• Norwegian j is usually pronounced like English y in yes
• the g in velger is pronounced
• r sounds are Norwegian, so they may not sound exactly like English r

Exact pronunciation varies a bit by dialect, but this approximation is a good start.

Sometimes, yes, depending on context. Jury in Norwegian often corresponds directly to jury, but in some situations English might prefer panel or judging panel.

Still, the most direct match is:

• juryen = the jury

So unless the context suggests otherwise, The jury chooses the winner is the best translation.

Only in some varieties of Norwegian.

• vinneren is the Bokmål definite form
• vinnaren is a Nynorsk form

If you are learning Bokmål, the sentence should be:

Juryen velger vinneren.

So the sentence you have is standard Bokmål.
