Ek weet nie of die bus reeds by die stasie is nie.

Afrikaans normally uses double negation. In a sentence like Ek weet nie ... nie, the first nie introduces the negation, and the second nie closes it.

So in:

Ek weet nie of die bus reeds by die stasie is nie.

the speaker is saying I do not know whether the bus is already at the station.

A useful pattern is:

Ek weet nie + clause + nie

This is one of the most noticeable features of standard Afrikaans, and it often feels unusual to English speakers at first because English usually uses only one negative word.

Here, of means whether / if.

So:

Ek weet nie of ... nie
= I don’t know whether ...

It introduces an embedded clause, just like whether in English:

• Ek wonder of hy kom. = I wonder whether he is coming.
• Sy vra of jy reg is. = She asks whether you are okay.

So in your sentence, of starts the part meaning whether the bus is already at the station.

Because after of, Afrikaans usually uses subordinate clause word order, where the conjugated verb often moves toward the end of the clause.

Compare:

• Main clause: Die bus is reeds by die stasie.
• Subordinate clause: ... of die bus reeds by die stasie is

This is similar to Dutch and somewhat like German subordinate clauses, but different from normal English word order.

So:

• Die bus is by die stasie. = main statement
• Ek weet nie of die bus by die stasie is nie. = embedded clause after of

Reeds means already.

So:

die bus reeds by die stasie
= the bus already at the station

However, in everyday speech, many speakers would more naturally use al instead of reeds:

• Ek weet nie of die bus al by die stasie is nie.

Both are correct, but al is often more common in conversation, while reeds can sound a bit more formal or written.

Yes, absolutely.

A very natural version is:

Ek weet nie of die bus al by die stasie is nie.

Both mean the same basic thing: I don’t know whether the bus is already at the station.

A rough guideline:

• al = very common in everyday speech
• reeds = also correct, sometimes slightly more formal or emphatic

By die stasie means at the station.

This is the normal choice when you mean location at or near a place.

• by die stasie = at the station
• na die stasie = to the station
• in die stasie = in the station, inside the building

So if the idea is that the bus has arrived and is now there, by die stasie is the natural phrase.

Die is the definite article in Afrikaans, meaning the.

Unlike many European languages, Afrikaans does not have grammatical gender for articles. So you use die for all singular definite nouns and also for plural definite nouns.

That means:

• die bus = the bus
• die stasie = the station

You do not need to learn different forms like masculine/feminine/neuter articles.

In standard Afrikaans, usually no. The final nie is an important part of the negative structure.

So standard Afrikaans is:

Ek weet nie of die bus reeds by die stasie is nie.

If you leave off the last nie, it will sound incomplete or non-standard to many speakers.

For learners, it is safest to remember that Afrikaans negation often works like a frame:

nie ... nie

The sentence has two parts:

1. Ek weet nie ... nie
   = I do not know ...

2. of die bus reeds by die stasie is
   = whether the bus is already at the station

So the full structure is:

Main clause + embedded clause introduced by of

You can think of it like this:

• Ek = I
• weet = know
• nie = not
• of = whether / if
• die bus = the bus
• reeds = already
• by die stasie = at the station
• is = is
• nie = final negative marker

As a direct statement, the word order changes:

Die bus is reeds by die stasie.
= The bus is already at the station.

Notice that in the direct statement, is comes earlier, after the subject:

• Die bus is reeds by die stasie.

But after of, it moves to the end:

• ... of die bus reeds by die stasie is

That contrast is very useful to learn, because it appears often in Afrikaans.

You would normally put the verb first:

Is die bus reeds by die stasie?
= Is the bus already at the station?

So compare:

• Die bus is reeds by die stasie. = statement
• Is die bus reeds by die stasie? = direct question
• Ek weet nie of die bus reeds by die stasie is nie. = embedded whether clause

These three patterns are worth learning together because they show how Afrikaans word order changes depending on the sentence type.
