Hulle vestig die kantoor hier.

In this sentence, hulle means they.

Afrikaans hulle is commonly used for the third-person plural:

• Hulle vestig ... = They establish ...

It can also mean them in other contexts, depending on sentence structure:

• Ek sien hulle. = I see them.

So hulle does not change form the way English changes they/them. You work out the role from the sentence.

Vestig usually means establish, set up, found, or sometimes base/locate, depending on context.

In Hulle vestig die kantoor hier, it suggests that they are:

• establishing the office here
• setting up the office here
• possibly locating/basing the office here

It is a slightly more formal word than something very casual. You may see it in business, official, or written contexts.

No. In Afrikaans, verbs generally do not change form according to the subject the way they do in English.

Compare:

• Ek vestig = I establish
• Jy vestig = you establish
• Hy vestig = he establishes
• Hulle vestig = they establish

So Afrikaans is simpler here than English: the verb stays the same.

Yes. In this sentence, vestig is being used as the present tense:

• Hulle vestig die kantoor hier. = They establish / are establishing the office here.

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

• They establish the office here
• They are establishing the office here

The exact English translation depends on context.

Die here is the definite article, meaning the.

So:

• die kantoor = the office

Afrikaans uses die for all genders and for both singular and plural definite nouns:

• die man = the man
• die vrou = the woman
• die kantoor = the office
• die kantore = the offices

So unlike some languages, you do not need different forms of the based on gender.

This is the normal word order for a straightforward main clause in Afrikaans:

Subject + Verb + Object + Place

• Hulle = subject
• vestig = verb
• die kantoor = object
• hier = place

So:

• Hulle vestig die kantoor hier.

This is very similar to normal English word order:

• They establish the office here.

Afrikaans main clauses usually keep the verb in the second position, which is an important rule in the language.

Hier means here, and in a sentence like this it often comes after the object as an adverb of place.

So:

• Hulle vestig die kantoor hier. = They establish the office here.

That placement is very natural in Afrikaans. Adverbs of place commonly appear toward the end of the clause, especially after the direct object.

Yes, but the structure changes if you move it to the front.

For example:

• Hier vestig hulle die kantoor.

This is still grammatical, but now hier is being emphasized. Because Afrikaans is a verb-second language, when hier moves to the front, the verb vestig must still stay in second position, and the subject hulle comes after the verb.

So:

• neutral: Hulle vestig die kantoor hier.
• emphasized place: Hier vestig hulle die kantoor.

Usually, yes: kantoor means office.

Depending on context, it can refer to:

• a room used for office work
• an office as a business location
• a branch or administrative office

In a sentence with vestig, it may sound more like setting up an office as an institution or location, not just placing a desk in a room.

Afrikaans usually uses double negation.

So:

• Hulle vestig die kantoor hier. = They establish the office here.
• Hulle vestig nie die kantoor hier nie. = They do not establish the office here.

Notice the two nie words:

1. one after the verb
2. one at the end of the clause

That double negative pattern is a very common feature of standard Afrikaans.

It is grammatical and natural, but vestig gives it a somewhat formal or business-like tone.

It sounds especially suitable in contexts like:

• companies
• government planning
• announcements
• official writing

In more casual speech, speakers might sometimes choose a different verb depending on the exact meaning, but vestig is perfectly normal if the idea is establishing or setting up an office.

A common past construction in Afrikaans uses het + past participle.

So:

• Hulle het die kantoor hier gevestig. = They established the office here.

Notice:

• het is the auxiliary
• gevestig is the past participle of vestig

This is one of the most common ways to talk about completed past actions in Afrikaans.
