Die aflewering is vandag vinnig, en die pakkie kom voor middagete aan.

Die is the definite article in Afrikaans, meaning the.

So:

• die aflewering = the delivery
• die pakkie = the package / parcel

Unlike languages such as German or Dutch, Afrikaans does not have grammatical gender for articles. That means die is used for the regardless of whether the noun would be masculine, feminine, or neuter in other languages.

Both word orders can be possible, but the placement changes the emphasis a little.

• is vandag vinnig puts today earlier, so it highlights that this is true today
• is vinnig vandag sounds a bit more like an afterthought: it is quick today

Afrikaans is fairly flexible with adverbs like vandag and vinnig, but word order often reflects what the speaker wants to emphasize.

In this sentence, vandag comes before vinnig because the speaker is framing the statement around today.

Here vinnig is being used after is, so it works like a predicate adjective: is quick / is fast.

In Afrikaans, adjectives often change form before a noun, but not usually after verbs like is.

Compare:

• die vinnige aflewering = the fast delivery
• die aflewering is vinnig = the delivery is fast

So in your sentence, vinnig stays in its basic form because it comes after is.

They refer to related but different things:

• aflewering = delivery
  This is the act, process, or service of delivering something.
• pakkie = package / parcel
  This is the actual physical item being delivered.

So the first half talks about the delivery, and the second half talks about the package itself.

This is because aankom is a separable verb in Afrikaans.

• Full verb: aankom = to arrive
• In a main clause, it often splits:
  • Die pakkie kom ... aan

So:

• Die pakkie kom voor middagete aan = The package arrives before lunch

This is very similar to separable verbs in Dutch and German.

More examples:

• Ek kom nou aan. = I’m arriving now.
• Wanneer kom hulle aan? = When do they arrive?

Yes, you could, and it would be understood.

• Die pakkie kom voor middagete aan is very natural and common.
• Die pakkie arriveer voor middagete is also possible, but it sounds a bit more formal or less everyday.

In ordinary speech, aankom / kom ... aan is often the more natural choice.

Afrikaans often leaves out the article in time expressions where English might also leave it out, or where English uses a fixed phrase.

• voor middagete = before lunch

Here middagete is being used in a general sense, not referring to one specific lunch as a separate object. That is why die is not needed.

Compare:

• voor middagete = before lunch
• voor die middagete would mean something more like before the lunch, referring to a specific lunch event or meal already known in context.

Yes, middagete means lunch.

Literally, it is made up of:

• middag = midday / noon
• ete = meal / eating

So middagete is the midday meal, i.e. lunch.

It does not usually mean noon by itself. If you want noon, Afrikaans normally uses middag.

Afrikaans, like English, often uses the present tense for scheduled or expected future events.

So:

• die pakkie kom voor middagete aan

can mean:

• the package arrives before lunch
• the package is arriving before lunch
• the package will arrive before lunch

The exact English translation depends on context, but the Afrikaans present tense is perfectly normal here.

It is acceptable here because the sentence joins two full clauses:

• Die aflewering is vandag vinnig
• die pakkie kom voor middagete aan

A comma before en is often used when two longer independent clauses are linked, especially to make the sentence easier to read.

In very short or simple sentences, people may sometimes omit it, but in this sentence the comma is natural and helpful.

Either can work, depending on context.

• vinnig often means fast
• it can also mean quick

In this sentence, the delivery is fast today or the delivery is quick today are both fine. English just chooses whichever sounds more natural in context.

For a delivery service, English often prefers fast a little more, but quick is not wrong.

Yes, it is understandable and grammatically normal.

A learner might just notice that the first half, Die aflewering is vandag vinnig, focuses on the speed of the delivery service/process, while the second half, die pakkie kom voor middagete aan, gives the concrete result: the package arrives before lunch.

So the sentence works well as:

• a comment about delivery speed today, and
• a statement about when the package will arrive

That makes it perfectly natural in ordinary usage.
