Sy skakel die eisbedrag volgens die wisselkoers om.

Because skakel ... om is a separable verb. The dictionary form is omskakel, but in a normal main clause Afrikaans splits it:

• skakel goes to the usual verb position
• om moves to the end

So:

• Sy skakel die eisbedrag volgens die wisselkoers om.

But in a subordinate clause, it usually stays together:

• ... dat sy die eisbedrag volgens die wisselkoers omskakel.

Also, this om is not the same as the om used in om te constructions.

Not usually. Skakel by itself can mean things like switch, connect, or even phone/call in some contexts. When you add om, the meaning becomes convert, change over, or switch from one form/system to another.

So the om is an important part of the meaning, not just a random extra word.

Here, Sy means she.

That can be confusing because Afrikaans sy can also mean his before a noun:

• Sy skakel ... om. = She converts ...
• sy geld = his money

In your sentence, Sy is a subject pronoun, so it means she.

Die is the Afrikaans definite article, meaning the.

Afrikaans uses die for:

• singular nouns
• plural nouns
• all grammatical genders

So unlike languages such as German or Dutch, you do not have to choose between different forms of the depending on gender or case.

Here it simply means:

• die eisbedrag = the claim amount
• die wisselkoers = the exchange rate

Volgens means according to, in accordance with, or based on.

So volgens die wisselkoers means that the conversion is being done according to the exchange rate. It tells you the basis or standard used for the conversion.

It does not mean physically following something. It is more like using the exchange rate as the rule or reference.

Eisbedrag is a compound noun, which is very common in Afrikaans.

It is made up of:

• eis = claim
• bedrag = amount

Together:

• eisbedrag = claim amount

Afrikaans often writes compounds as one word, where English may use two words or a hyphen.

The same is true of wisselkoers:

• wissel = exchange
• koers = rate
• wisselkoers = exchange rate

A useful rule: in Afrikaans compounds, the last part is usually the main part. So an eisbedrag is a type of bedrag.

A common past-tense version would be:

• Sy het die eisbedrag volgens die wisselkoers omgeskakel.

Afrikaans often uses het + a past participle to express the past.

For the separable verb omskakel, the past participle is:

• omgeskakel

So the sentence becomes:

• Sy het ... omgeskakel.

Notice that in the participle, the parts are no longer split.

In a yes/no question, the finite verb moves to the front:

• Skakel sy die eisbedrag volgens die wisselkoers om?

So the pattern is:

• statement: Sy skakel ... om.
• question: Skakel sy ... om?

The separable particle om still stays at the end.
