Voordat ons geld oorplaas, gaan ons die bankbesonderhede na.

Voordat means before. It introduces a subordinate clause, and in Afrikaans that usually sends the verb to the end of that clause.

So:

• Voordat ons geld oorplaas
• literally follows the pattern before we money transfer

That is why oorplaas comes at the end of the first clause.

Not in this sentence. Here gaan ... na is the split form of the verb nagaan, which means check, verify, or go over.

So:

• Ons gaan die bankbesonderhede na
• means We check the bank details

It does not mean we go to the bank details or anything like that.

Because nagaan is a separable verb. In a main clause, the first part can move into the normal verb position, while the particle stays at the end.

So:

• dictionary form: nagaan
• main clause: Ons gaan die bankbesonderhede na
• subordinate clause: ... dat ons die bankbesonderhede nagaan

This split is very common in Afrikaans.

Afrikaans main clauses normally put the finite verb in the second position. The whole Voordat... clause counts as the first element, so the verb must come next.

That gives:

• Voordat ons geld oorplaas, gaan ons die bankbesonderhede na.

If the main clause stood by itself, it would be:

• Ons gaan die bankbesonderhede na.

Yes, it can split. The basic verb is oorplaas, and in a main clause it often appears split:

• Ons plaas geld oor.

But in a subordinate clause, or in some infinitive forms, it appears as one word:

• Voordat ons geld oorplaas...
• Ons wil geld oorplaas.

So the sentence is using the normal subordinate-clause form.

It is a compound noun made from:

• bank = bank
• besonderhede = details / particulars

So bankbesonderhede means bank details. Afrikaans very often joins nouns together into one word, where English would usually write two words.

Because die is the definite article for both singular and plural in Afrikaans.

So:

• die bank = the bank
• die bankbesonderhede = the bank details

Afrikaans does not have separate forms like singular the and plural the. It just uses die for both.

Because this is not an infinitive like English to transfer. After voordat, Afrikaans uses a full clause: before we transfer money.

So:

• Voordat ons geld oorplaas = Before we transfer money

If you wanted an infinitive construction, you could say something like:

• om geld oor te plaas = to transfer money

Notice that with te, the separable verb splits: oor te plaas.

Grammatically, it is present tense. But Afrikaans, like English, often uses the present tense for routines, procedures, or near-future actions.

So this can sound like:

• Before we transfer money, we check the bank details
• or, depending on context, Before we transfer money, we will check the bank details

If you wanted to make the future more explicit, you could use sal:

• Voordat ons geld oorplaas, sal ons die bankbesonderhede nagaan.

Because each clause has its own subject. Afrikaans normally keeps the subject explicit in both parts:

• Voordat ons geld oorplaas
• gaan ons die bankbesonderhede na

English can sometimes shorten this idea, as in Before transferring money..., but the Afrikaans sentence here uses two full clauses, so ons appears twice.
