Sy nooi ons weer vir aandete, en sy kook so goed dat niemand vroeg wil vertrek nie.

Here vir means for, not a direct-object marker.

With nooi, Afrikaans often uses:

• nooi iemand vir ete / vir koffie / vir aandete = invite someone for a meal or drink
• nooi iemand na die huis = invite someone to the house

So Sy nooi ons weer vir aandete means she invites us again for dinner.

Weer here means again.

So:

• Sy nooi ons weer vir aandete = She invites us for dinner again

Its position is natural in Afrikaans. It often comes after the object or in the middle of the clause. You could move it for emphasis in some contexts, but this version sounds very normal.

Aandete is a compound noun:

• aand = evening
• ete = meal / food

So literally it is the evening meal. In English, that may be translated as dinner or supper, depending on the speaker and context.

Because the sentence has two coordinated clauses:

• Sy nooi ons weer vir aandete
• en sy kook so goed dat niemand vroeg wil vertrek nie

Afrikaans often repeats the subject in the second clause, just as English often does:

• She invites us again for dinner, and she cooks so well...

You can sometimes leave the second subject out if it is clearly the same person, but repeating sy is completely normal and often clearer.

Afrikaans does not have a separate -ly form like English. The same word often works as both adjective and adverb.

So:

• ’n goeie kok = a good cook
• Sy kook goed = She cooks well

In this sentence, goed is describing how she cooks, so in English we translate it as well.

So ... dat is a very common Afrikaans pattern meaning so ... that.

Here:

• sy kook so goed = she cooks so well
• dat niemand vroeg wil vertrek nie = that nobody wants to leave early

So the whole structure shows degree + result:

• so well that nobody wants to leave early

Because dat introduces a subordinate clause.

After dat, Afrikaans typically pushes the verb part toward the end of the clause. That is why you get:

• dat = that
• niemand = nobody
• vroeg = early
• wil vertrek = wants to leave
• nie = final negative marker

So the pattern is very typical Afrikaans subordinate-clause word order.

This is a classic Afrikaans feature: double negation.

A negative word such as:

• niemand = nobody
• niks = nothing
• nooit = never

usually still needs a final nie later in the clause.

So:

• Niemand wil vertrek nie = Nobody wants to leave

You do not add an extra earlier nie here. The negative word niemand does the first negative job, and the final nie completes the pattern.

Vertrek is the verb to leave / depart.

In this sentence:

• vroeg wil vertrek = want to leave early

It is a normal, neutral word. In some contexts, weggaan is another common way to say go away / leave, but vertrek works very well here.

Vroeg is an adverb meaning early, and in Afrikaans it commonly comes before the verb group.

So:

• niemand vroeg wil vertrek nie = nobody wants to leave early

That placement is very natural in Afrikaans, especially inside a dat clause.
