Aan die een kant: waarborgbewys; maar aan die ander kant: arbeidskoste.

This is a very common contrast pattern in Afrikaans, just like on the one hand ... on the other hand in English.

• aan = on / at
• die = the
• een = one
• ander = other
• kant = side

So literally it is on the one side ... on the other side, but idiomatically it means on the one hand ... on the other hand.

No.

• een means one
• 'n means a / an

So die een kant is the one side, not the a side.

This is an important distinction for English speakers, because both can sometimes sound a bit like unstressed one in English, but in Afrikaans they are different words with different jobs.

Maar means but, and it strengthens the contrast.

So the structure is:

• aan die een kant = on the one hand
• maar = but
• aan die ander kant = on the other hand

Afrikaans often likes this extra marker of contrast. It makes the opposition between the two parts more explicit. In some contexts, maar could be left out, but with it, the contrast sounds clearer and more natural.

Yes. Afrikaans very often writes compound nouns as one word.

Waarborgbewys is made up of:

• waarborg = warranty / guarantee
• bewys = proof / certificate / document

So waarborgbewys is a compound noun meaning something like a warranty document, proof of warranty, or warranty certificate, depending on context.

Not always in the narrow English sense.

On its own, bewys often does mean proof. But in compounds, it can refer to a document that serves as proof. So in waarborgbewys, it is not abstract proof in general; it is more like a document showing that the warranty exists.

That is very normal in Afrikaans compound nouns.

Yes, it is also a compound noun.

It is made from:

• arbeid = labor / work
• koste = costs

So arbeidskoste literally means labor costs or labor charges.

This is another very typical Afrikaans compound: instead of writing two separate words, Afrikaans combines them into one noun.

Because this sentence is written in a shortened, list-like style.

After the colons, the nouns are presented almost like labels or headings:

• waarborgbewys
• arbeidskoste

In a fuller sentence, you might see articles, depending on the context, for example:

• 'n waarborgbewys
• die arbeidskoste

But in this compact contrast structure, leaving the nouns bare sounds natural.

Not really in the full, textbook sense. It is more like an elliptical or note-style sentence.

Afrikaans often allows this kind of shortened structure when the contrast is clear. A fuller version might include extra words such as is daar or some other verb phrase, but they are omitted because the meaning is already understood from the context.

So this is natural writing, just more compact than a fully expanded sentence.

They organize the sentence into two balanced parts.

• The first colon introduces the first item: waarborgbewys
• The semicolon separates the two contrasting halves
• The second colon introduces the second item: arbeidskoste

So the punctuation helps present this as a neat comparison or contrast. In more informal writing, you might see commas or dashes instead, but this punctuation gives it a structured, slightly formal feel.
