Niemand weet of die spyskaart hier beskikbaar is nie.

Here of means whether or if, not or.

Afrikaans of has two common uses:

• or: tee of koffie = tea or coffee
• whether/if: Ek weet nie of hy kom nie = I don’t know whether he is coming

After verbs like weet (know), vra (ask), and wonder (wonder), of often introduces an indirect yes/no question.

Because of introduces a subordinate clause, and in Afrikaans subordinate clauses normally send the finite verb to the end.

So:

• main clause: Die spyskaart is hier beskikbaar
• subordinate clause: of die spyskaart hier beskikbaar is

This is very common in Afrikaans after words like dat, omdat, as, terwyl, and of.

Afrikaans does often use a two-part negative, but words like niemand already count as the first negative element.

So in this sentence:

• Niemand = nobody / no one
• final nie = the closing negative particle

That is why you get:

• Niemand weet ... nie

and not two separate nie particles.

Compare:

• Ek weet nie = I do not know
• Niemand weet nie would be nonstandard in this context
• Niemand weet dit nie = Nobody knows that

The final nie completes the negation of the main clause, not the of clause by itself.

So the structure is basically:

• Niemand weet ... nie = Nobody knows ...

The part after of is simply what nobody knows:

• of die spyskaart hier beskikbaar is = whether the menu is available here

So the sentence means that the knowing is negated, not that available is negated.

If you wanted the subordinate clause itself to be negative, the wording would be different.

In standard Afrikaans, no. That would sound wrong because niemand already provides the first negative idea.

The normal pattern is:

• Niemand weet of die spyskaart hier beskikbaar is nie.

So with niemand, you do not add an extra nie after weet.

Because spyskaart is a singular countable noun, and in Afrikaans that usually needs a determiner such as die or ’n.

Here die spyskaart means the menu.

Using just spyskaart by itself in this sentence would sound incomplete or ungrammatical in standard Afrikaans.

Because beskikbaar is being used as a predicate adjective after the verb is.

In Afrikaans:

• after a linking verb like is, the adjective usually stays in its basic form
  
  • Die spyskaart is beskikbaar
• before a noun, the adjective often takes -e
  
  • die beskikbare spyskaart

So:

• beskikbaar = predicate form
• beskikbare = attributive form

That is the normal position in this kind of clause.

In the subordinate clause:

• die spyskaart = subject
• hier = adverb of place
• beskikbaar = complement/adjective
• is = verb at the end

So the order is:

• of die spyskaart hier beskikbaar is

This is a natural Afrikaans word order. English speakers often expect the verb earlier, but in subordinate clauses Afrikaans usually keeps the verb last.

Use of when the meaning is whether/if. Use dat when the meaning is that.

Compare:

• Niemand weet of die spyskaart hier beskikbaar is nie.
  Nobody knows whether the menu is available here.

• Niemand weet dat die spyskaart hier beskikbaar is nie.
  Nobody knows that the menu is available here.

So of introduces uncertainty or an indirect question, while dat introduces a statement or fact.

Yes. Spyskaart is the standard Afrikaans word for menu, especially in restaurants.

It is a compound:

• spys = food/dish
• kaart = card/list

So it literally feels a bit like food list/card, but learners should just treat it as the normal word for menu.
