Die oorspronklike verpakking is onoopgemaak.

Die means the.

It is the normal definite article in Afrikaans for singular and plural nouns. Here it is capitalized only because it is the first word of the sentence.

So:

• die verpakking = the packaging

Because it is an adjective placed before the noun.

In Afrikaans, adjectives used attributively (that is, directly before a noun) often take an -e ending.

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

This is similar to how Afrikaans often has a different adjective form before a noun than after is.

Compare:

• Die verpakking is oorspronklik. = The packaging is original.
• die oorspronklike verpakking = the original packaging

Verpakking means packaging or pack/container/wrapping, depending on context.

In this sentence, it usually means the item's original packaging as a whole, not necessarily just a single wrapper. English also often uses packaging this way.

So die oorspronklike verpakking is a very natural way to say the original packaging.

Is is the present-tense form of wees (to be), just like English is.

So the sentence structure is:

• Die oorspronklike verpakking = the original packaging
• is = is
• onoopgemaak = unopened

That makes the full sentence:

• The original packaging is unopened.

It literally means un-opened.

It is made from:

• on- = un-, not-
• oopgemaak = opened

So:

• onoopgemaak = unopened

This is a very common Afrikaans pattern. The prefix on- often works like English un-:

• moontlik = possible

• onmoontlik = impossible

• bekend = known
• onbekend = unknown

It comes from the verb oopmaak, which means to open.

The past participle of oopmaak is oopgemaak, meaning opened.

So the build is:

• oopmaak = to open
• oopgemaak = opened
• onoopgemaak = unopened

This is especially useful to notice because oopmaak is a separable verb:

• Ek maak die boks oop. = I open the box.
• Die boks is oopgemaak. = The box has been opened / was opened.

Because in Afrikaans, forms with prefixes like on- are normally written as a single word.

So:

• on
  • oopgemaak → onoopgemaak

This is the normal spelling, just as English writes unopened as one word.

Because here it comes after is, not before a noun.

After is, the adjective is being used predicatively, and predicative adjectives in Afrikaans usually do not take the -e ending.

Compare:

• die onoopgemaakte verpakking = the unopened packaging
• Die verpakking is onoopgemaak. = The packaging is unopened.

So:

• before the noun: often -e
• after is: usually no -e

Yes, you could, and it would be understandable.

That version means something like:

• The original packaging has not been opened.

The difference is mainly in style and emphasis:

• is onoopgemaak = is unopened
  
  • compact, adjective-based description
• is nie oopgemaak nie = has not been opened
  
  • more explicitly verbal, focusing on the action not happening

Also, nie ... nie is the normal Afrikaans negative pattern.

Yes, in this sentence it is very similar to English.

The pattern is:

• Die = The
• oorspronklike = original
• verpakking = packaging
• is = is
• onoopgemaak = unopened

So the sentence order is straightforward:

subject + is + adjective

This makes it a very beginner-friendly sentence structurally, even though some of the words are long.

A rough English-friendly guide would be:

• oorspronklike ≈ OAR-sprong-kuh-luh-kə
• onoopgemaak ≈ on-OH-up-khuh-maakt

A few helpful notes:

• oo is usually a long o sound.
• g in Afrikaans is usually a throaty sound, not an English g.
• aa is a long a sound.
• Stress often falls earlier in the word than an English speaker might expect.

If you want to sound natural, it helps to hear these words spoken, because Afrikaans vowel length and the g/ch sounds matter a lot.
