Ons reageer op die oortredingskennisgewing.

It means we.

Afrikaans ons can mean we or us depending on its role in the sentence. Here it is the subject of the verb reageer, so it means we.

Usually, no. In Afrikaans, verbs normally do not change according to the subject.

So you get:

• Ek reageer — I respond
• Jy reageer — you respond
• Ons reageer — we respond
• Hulle reageer — they respond

That is one of the nice simplifications of Afrikaans compared with English.

It can mean either one.

Afrikaans often uses the simple present where English might use either:

• we respond
• we are responding

Context tells you which is meant. If you want to make right now clearer, you can add a word like nou:

• Ons reageer nou op die oortredingskennisgewing. — We are responding to the notice now.

Because reageer op is the normal Afrikaans pattern for react to or respond to.

Even though op often translates as on or upon, after reageer it corresponds to English to:

• reageer op iets — react/respond to something

So in this sentence, op is not optional decoration; it is part of the standard construction.

No, that would sound wrong.

The verb reageer normally needs op before the thing being reacted to. So the natural sentence is:

• Ons reageer op die oortredingskennisgewing.

Think of it as similar to learning that English says respond to something, not just respond something.

It means the.

A very useful thing to remember is that Afrikaans uses die as the definite article for:

• singular nouns
• plural nouns
• all genders

So Afrikaans does not have separate forms like the for masculine/feminine/neuter, and it does not change here.

Also, die in Afrikaans is usually pronounced roughly like dee, not like the English verb die.

Because Afrikaans, like Dutch and German, very often forms compound nouns by writing them as a single word.

This one can be broken down as:

• oortreding — offence / violation / infringement
• kennisgewing — notice / notification

Together, oortredingskennisgewing is literally something like violation-notice or infringement notice.

English often prefers separate words, but Afrikaans commonly joins them.

That -s- is a linking element used in many Afrikaans compounds.

So the structure is:

• oortreding
• -s-
• kennisgewing

The -s- does not usually add a separate meaning by itself; it helps connect the parts into a natural-sounding compound. English learners often want every letter to have a clear standalone meaning, but in compounds like this, the linker is just part of normal word formation.

Yes. This is a standard main-clause word order:

• Ons — subject
• reageer — verb
• op die oortredingskennisgewing — prepositional phrase

So it follows the basic pattern you would expect in a simple statement.

One important Afrikaans rule, though, is that the finite verb stays in second position in main clauses. For example:

• Vandag reageer ons op die oortredingskennisgewing.

Here Vandag comes first, so reageer still stays second, and ons moves after it.

In a subordinate clause, the verb usually moves toward the end.

For example:

• Ek weet dat ons op die oortredingskennisgewing reageer.
  — I know that we are responding to the infringement notice.

So compared with the main clause:

• Ons reageer op die oortredingskennisgewing.

the subordinate clause after dat puts reageer at the end:

• ... dat ons op die oortredingskennisgewing reageer

This is a very common Afrikaans word-order pattern to get used to early.
