Ons gaan voertuigbesonderhede by wyse van registrasiesertifikate na.

Because the verb here is nagaan, a separable verb in Afrikaans.

In a normal main clause, the conjugated part goes to the usual verb position near the front, and the particle goes to the end:

• Ons gaan ... na. = We check / examine / verify ...
• infinitive: nagaan
• with om ... te: om ... na te gaan
• after an auxiliary: Ons sal ... nagaan

So gaan and na belong together even though they are split apart.

Not by itself. In this sentence, gaan is part of the verb nagaan.

That means:

• Ons gaan voertuigbesonderhede na. = We check / verify vehicle details.

It does not mean physical movement, and it is not the future construction going to.

Compare:

• Ons gaan voertuigbesonderhede na. = We check/verify vehicle details.
• Ons gaan voertuigbesonderhede nagaan. = We are going to check/verify vehicle details.

That second sentence uses gaan as a future helper verb, plus the full infinitive nagaan at the end.

No. Here na is a verb particle, not a preposition.

In other words, it is the second part of nagaan. It does not mean to or after in this sentence.

So in:

• Ons gaan voertuigbesonderhede ... na

the na belongs with gaan, not with registrasiesertifikate.

Because Afrikaans, like Dutch and German, very often forms compound nouns as one word.

So:

• voertuig
  • besonderhede = voertuigbesonderhede
    (vehicle details)
• registrasie
  • sertifikate = registrasiesertifikate
    (registration certificates)

This is very normal in Afrikaans. English often writes these as separate words, but Afrikaans usually joins them.

Because Afrikaans often leaves out the article when talking about things in a general or non-specific way, especially with plural nouns.

So:

• voertuigbesonderhede = vehicle details, in a general sense
• registrasiesertifikate = registration certificates, in a general sense

If you meant specific ones, you could add die:

• die voertuigbesonderhede
• die registrasiesertifikate

And if it were one unspecified certificate, you could say:

• ’n registrasiesertifikaat

By wyse van is a fairly formal expression meaning:

• by means of
• by way of
• using

So by wyse van registrasiesertifikate means something like by means of registration certificates.

This phrase sounds formal or administrative. In more everyday language, people might use something simpler depending on context, such as met or deur middel van.

Yes. It sounds quite formal, bureaucratic, or administrative.

The main reason is the phrase by wyse van, which is not especially conversational. The long compound nouns also add to that official tone.

A more everyday version might use a simpler wording, but the original sentence is perfectly normal in official or written contexts.

Because Afrikaans often uses the simple present where English would naturally use either:

• check
• are checking

So Ons gaan ... na can be translated according to context as:

• We check ...
• We are checking ...

Afrikaans does have ways to emphasize ongoing action, but very often the plain present tense is enough.

Because nagaan is separable, its shape changes depending on the structure.

Examples:

• Main clause:
  Ons gaan voertuigbesonderhede na.

• With an auxiliary:
  Ons sal voertuigbesonderhede nagaan.

• With future gaan:
  Ons gaan voertuigbesonderhede nagaan.

• With om ... te:
  om voertuigbesonderhede na te gaan

• Past participle:
  Ons het voertuigbesonderhede nagegaan.

So learning nagaan as a separable verb is the key to understanding all these forms.
