De spiller videre.

In modern Norwegian, de usually means they.

Because this sentence starts with De, it is capitalized automatically, so the capital letter does not by itself mean it is the formal you.

That said, De with a capital letter can also be an old-fashioned or very formal way to say you. In most everyday modern Norwegian, that usage is rare. Without special context, learners should usually read De spiller videre as they continue playing / they play on.

Spiller is the present tense form of the verb.

• infinitive: å spille = to play
• present tense: spiller = play / is playing / are playing

So in a full sentence with a subject like de, you normally use spiller, not spille.

No. In Norwegian, verbs do not usually change for person or number in the present tense.

So you get:

• jeg spiller = I play
• du spiller = you play
• han/hun spiller = he/she plays
• vi spiller = we play
• de spiller = they play

This is simpler than English, where he plays is different from I play.

Here, videre is an adverb meaning something like:

• on
• further
• continuing

So spiller videre means that the playing continues.

In English, we often use a different structure, like continue playing or play on, but Norwegian can express that idea with verb + videre.

Because videre is an adverb, and in a simple main clause like this, it commonly comes after the finite verb.

So the pattern is:

• De = subject
• spiller = finite verb
• videre = adverb

This word order is very normal in Norwegian.

Yes. De is the subject form, like English they.

If you need the object form, Bokmål normally uses dem, like English them.

Examples:

• De spiller videre. = They continue playing.
• Jeg ser dem. = I see them.

So in your sentence, de is used because they are the ones doing the action.

Yes. That is another natural way to express a similar idea.

• De spiller videre = They play on / continue playing
• De fortsetter å spille = They continue to play / continue playing

The first version is a bit more compact and idiomatic in some contexts. The second makes the idea of continuing more explicit.

You put ikke after the verb:

• De spiller ikke videre.

That means They do not continue playing or They aren’t playing on.

This placement is very typical in Norwegian main clauses:

• subject + verb + ikke
  • other elements

In a yes/no question, Norwegian usually puts the verb first:

• Spiller de videre?

This is a very common pattern:

• statement: De spiller videre.
• question: Spiller de videre?

A careful approximate pronunciation is:

• De ≈ dee
• spiller ≈ SPILL-er
• videre ≈ VEE-deh-reh

Very roughly: dee SPILL-er VEE-deh-reh

A few notes:

• sp in spiller is pronounced like English sp in spin
• the ll is a clear double consonant
• pronunciation varies by dialect, especially in videre

If you want a safe learner version, saying something close to dee SPILL-er VEE-deh-reh will be understood.
