Die vervangingsproduk moet in die oorspronklike verpakking verpak word.

Because the sentence contains two different nouns, and each one has its own definite article:

• die vervangingsproduk = the replacement product
• die oorspronklike verpakking = the original packaging

In Afrikaans, die is the definite article for all nouns, whether singular or plural. Unlike English, Afrikaans does not change the article based on gender.

So:

• die produk = the product
• die verpakking = the packaging
• die produkte = the products

It is the same word each time: die.

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

It is made up of:

• vervanging = replacement
• produk = product

Together:

• vervangingsproduk = replacement product

Afrikaans often combines words into one longer noun, just like German and sometimes English does. Compare:

• replacement product in English = two words
• vervangingsproduk in Afrikaans = one word

The -s- in the middle is a linking sound that often appears in compounds.

They come from the same basic idea, but they are different parts of speech:

• verpakking = packaging / package as a noun
• verpak = to package / packaged as a verb or past participle form

In this sentence:

• die oorspronklike verpakking = the original packaging
  Here verpakking is a noun.
• verpak word = be packaged
  Here verpak is part of the passive verb construction.

So the sentence uses both:

• the thing something must be in = verpakking
• the action done to the product = verpak

This is a passive construction.

• verpak = packaged
• word = become / be, used to form the passive

So:

• Die vervangingsproduk moet ... verpak word. = The replacement product must be packaged ...

Afrikaans commonly forms the passive with:

• word for a present/future or general passive
• is for a completed passive in some contexts

Compare:

• Die produk word verpak. = The product is being packaged / is packaged.
• Die produk is verpak. = The product is packaged / has been packaged.

In your sentence, verpak word means must be packaged.

Because Afrikaans often splits verb parts in main clauses.

Here the structure is:

• Die vervangingsproduk = subject
• moet = modal verb
• in die oorspronklike verpakking = prepositional phrase
• verpak word = passive infinitive idea at the end

Afrikaans word order often puts the finite verb early in the sentence, while other verb parts go to the end.

So:

• moet appears in second position
• verpak word comes at the end

This is very typical after modal verbs such as:

• moet = must
• kan = can
• sal = will
• mag = may

Example:

• Die boek moet gelees word. = The book must be read.
• Die kos moet warm bedien word. = The food must be served warm.

Because Afrikaans does not use to in the same way English does before infinitives.

English says:

• must be packaged

Afrikaans says:

• moet verpak word

There is no separate word that corresponds directly to English to here.

That is normal in Afrikaans after modal verbs like moet.

Compare:

• Ek moet gaan. = I must go.
• Sy kan swem. = She can swim.
• Die produk moet verpak word. = The product must be packaged.

So the absence of to is not strange in Afrikaans grammar.

oorspronklike means original.

The base adjective is:

• oorspronklik = original

Before a noun, Afrikaans adjectives often take an extra -e ending:

• oorspronklik → oorspronklike verpakking

So:

• die oorspronklike verpakking = the original packaging

This is very common in attributive position, meaning when the adjective comes before the noun.

Compare:

• ’n nuwe produk = a new product
• die nuwe produk = the new product
• oorspronklike verpakking = original packaging

Learners often just need to get used to the fact that Afrikaans adjectives often look slightly different before nouns.

It usually means in the original packaging or in its original packaging.

Breaking it down:

• in = in
• die oorspronklike verpakking = the original packaging

In practical usage, this often refers to the item being returned or sent back in the packaging it originally came in.

Depending on context, English might translate it as:

• in the original packaging
• in its original packaging
• in the original package

But verpakking most naturally corresponds to packaging.

Only if the broader context clearly involves a return.

The actual Afrikaans sentence says:

• Die vervangingsproduk moet in die oorspronklike verpakking verpak word.

A direct meaning is:

• The replacement product must be packaged in the original packaging.

If the surrounding context is about returns, exchanges, or shipping, an English speaker might choose a more natural translation depending on the situation. But grammatically, the Afrikaans sentence itself specifically says must be packaged, not must be returned.

So:

• verpak word = be packaged
• not teruggestuur word = be returned / sent back

It sounds fairly formal or instructional.

You would expect this kind of sentence in places like:

• return policies
• product instructions
• store terms and conditions
• shipping requirements

That is because it uses a fairly official style:

• vervangingsproduk = a formal compound noun
• moet = must
• verpak word = passive structure often used in rules and instructions

In everyday speech, people might choose something simpler, depending on the context. But for written policies or instructions, this sentence sounds normal and appropriate.
