Jag vill inte vänta längre.

Because vill is the present tense form of the verb vilja (to want).

Swedish verbs do not change for person the way English does. So:

• jag vill = I want
• du vill = you want
• han/hon vill = he/she wants
• vi vill = we want

The form stays vill for all subjects in the present tense.

After modal verbs like vill (want to, in this construction), Swedish normally uses the infinitive without att.

So:

• Jag vill vänta = I want to wait
• Hon kan komma = She can come
• Vi måste gå = We must go

Here, vänta is the infinitive (wait / to wait), but after vill, you do not say att vänta.

In a main clause, Swedish usually places inte after the finite verb.

In this sentence, the finite verb is vill, so:

• Jag vill inte vänta längre.

This is a very common word order pattern in Swedish:

• subject + finite verb + inte
  • rest of sentence

Compare:

• Jag kommer inte. = I am not coming.
• Hon talar inte svenska. = She does not speak Swedish.

Usually not in a normal main clause like this.

Jag vill inte vänta längre is the natural word order.

If you moved inte, it would either sound wrong or create a different structure. For example, Jag inte vill vänta längre is not standard Swedish main-clause word order.

So for learners, the safest rule is:

• in main clauses, put inte after the finite verb

Here längre means any longer or anymore, not just longer in a simple time-length sense.

So Jag vill inte vänta längre means:

• I don’t want to wait any longer.
• I don’t want to wait anymore.

In negative sentences, längre often has this any longer / anymore meaning.

They are not interchangeable here.

• längre relates to longer / any longer, often in time or continuation
• mer means more

So:

• Jag vill inte vänta längre. = I don’t want to wait any longer.
• Jag vill inte vänta mer. can sometimes be heard in speech, but längre is the more idiomatic choice for any longer in this kind of sentence.

A useful learner rule is:

• use längre for any longer
• use mer for more

The dictionary form is vänta, which is the infinitive and means to wait.

In this sentence, it stays in the infinitive because it follows vill.

Some common forms are:

• vänta = to wait
• väntar = wait / am waiting / is waiting
• väntade = waited
• väntat = waited (supine/past participle-related form depending on use)

It is fairly close, but not completely.

English:

• I do not want to wait any longer.

Swedish:

• Jag vill inte vänta längre.

A big difference is that Swedish does not need a helper verb like do for negation here. English says do not want, but Swedish simply says vill inte.

So Swedish is structurally more like:

• I want not wait any longer

Even though that is not natural English, it helps show the Swedish pattern.

Yes, in other contexts längre can mean farther/further or longer.

For example:

• Han gick längre bort. = He went farther away.
• Vi stannade längre. = We stayed longer.

But in Jag vill inte vänta längre, because of the negative context, it is understood as any longer / anymore.

A few possibilities are:

• Jag vill inte vänta längre. = neutral and natural
• Jag tänker inte vänta längre. = I’m not going to wait any longer / I refuse to wait any longer
  This sounds stronger and more determined.
• Jag vill inte vänta mer. = understandable, but usually less idiomatic than längre in this meaning

So the original sentence is a very natural everyday way to say it.

Vänta is pronounced roughly like VEN-ta, but with a Swedish ä sound rather than a plain English e.

A rough guide:

• vän sounds a bit like the ven in vent, but not exactly
• ta is a clear ta sound

Also, Swedish pronunciation is generally crisp, and the first syllable is stressed:

• VÄN-ta

Because längre here functions as an adverb, not as a noun or adjective needing an article.

It modifies the idea of waiting:

• vänta längre = wait longer / wait any longer

So nothing extra is needed. The sentence is complete as it is:

• Jag vill inte vänta längre.

Not in normal modern Swedish. That word order sounds wrong.

The natural sentence is:

• Jag vill inte vänta längre.

Keep these roles in mind:

• inte negates the verb phrase
• längre adds the meaning any longer

So the standard order is:

• subject + finite verb + inte
  • infinitive + längre
