Daar praten we later over.

Because Dutch main clauses usually follow the V2 rule: the finite verb must be in the second position.

In this sentence, Daar is placed first for emphasis or topic, so the verb praten has to come next:

• Daar praten we later over.

If you start with the subject instead, then you get:

• We praten daar later over.

Both are correct, but the word order changes because Dutch wants the finite verb in second position.

This happens because praten over is the combination used for to talk about, and Dutch often splits this kind of structure when it uses a pronominal adverb like daarover / erover.

So:

• daar + over = daarover

But in many sentences, Dutch splits them:

• Daar praten we later over.

So over belongs with daar, even though it appears later in the sentence.

This is very normal Dutch. Compare:

• Ik denk daar vaak aan. = I often think about that.
• We wachten er nog op. = We’re still waiting for it.

Because after many prepositions, Dutch usually does not use a plain demonstrative pronoun like dat for things. Instead, it uses a pronominal adverb:

• daar + preposition

So for about that, Dutch prefers:

• daarover
• or split: daar ... over

rather than:

• over dat (usually not natural here)

This is one of the big differences from English. English says about that, but Dutch often says the equivalent of there-about.

Yes. That is also correct.

You have two common possibilities:

• Daar praten we later over.
• Daarover praten we later.

Both mean the same thing.

The split version (daar ... over) is extremely common in everyday Dutch. The unsplit version (daarover) is also normal, and can sound a bit more compact or slightly more formal depending on context.

The main difference is stress and emphasis.

• We praten er later over.
  = neutral, unstressed, very common in everyday speech

• Daar praten we later over.
  = more emphasis on that

So er is the weak, unstressed version, while daar is stronger and more specific/emphatic.

Very often, if English stresses that, Dutch may use daar. If it is just a neutral reference, Dutch often uses er.

Yes. Praten over means to talk about.

Examples:

• We praten over school. = We talk about school.
• Ze praten over het probleem. = They are talking about the problem.

So in your sentence, over is not random—it is required by the verb phrase praten over.

Yes, absolutely.

That version starts with the subject:

• We praten daar later over.

This is a very natural neutral sentence.

Compare:

• We praten daar later over. = neutral
• Daar praten we later over. = puts that in first position, often for emphasis, contrast, or because it is the topic

So the original sentence is not the only possible word order.

Later is quite flexible, but some positions are more natural than others.

Common natural versions:

• Daar praten we later over.
• We praten daar later over.
• Later praten we daarover.
• We praten later daarover. (possible, but less common/natural than We praten daar later over)

In everyday Dutch, adverbs like later often come in the middle part of the sentence, before the final preposition.

Yes. That is also correct.

This version uses the future auxiliary zullen:

• Daarover zullen we later praten.

It can sound a little more explicit or slightly more formal than the simple present:

• Daar praten we later over.

Dutch often uses the present tense for future meaning when the context is clear, so the original sentence is very natural.

It is neutral everyday Dutch. It works well in both spoken and written language.

• Daar praten we later over. sounds very natural in conversation.
• It is not slang.
• It is not especially formal either.

So it is a very useful sentence pattern to learn.

It is called a pronominal adverb.

Dutch forms these by combining:

• er / daar / hier / waar with
• a preposition

For example:

• erover = about it
• daarover = about that
• hierover = about this
• waarover = about what / what about

These are very important in Dutch, because they are used all the time instead of forms that English speakers might expect, such as over het or over dat.

So your sentence is a great example of a very common Dutch grammar pattern.
