Waar ontmoet ons?

• Waar = where
• ontmoet = meet
• ons = we / us

So the sentence literally looks like Where meet we?, but in natural English it is Where do we meet?

Because waar is the question word, and Afrikaans normally puts question words first in wh- questions.

So:

• Waar ontmoet ons? = Where do we meet?
• Wanneer ontmoet ons? = When do we meet?
• Hoekom ontmoet ons? = Why do we meet?

This is similar to English putting where, when, why, etc. at the front.

Afrikaans does not use a helping verb like do in this kind of question.

English needs:

• Where do we meet?

Afrikaans simply uses the main verb:

• Waar ontmoet ons?

This is very common. Afrikaans often looks more direct than English in questions.

In a main-clause question with a question word first, Afrikaans usually puts the verb next. This is the normal verb-second pattern.

So the structure is:

• Waar
  • ontmoet
    • ons

Compare the statement:

• Ons ontmoet daar. = We meet there.

In the statement, ons comes first.
In the question, the question word takes first place, so the verb moves before the subject:

• Waar ontmoet ons?

Here it means we.

Afrikaans ons can correspond to both English we and us, depending on the sentence.

Examples:

• Ons ontmoet daar. = We meet there.
• Hy sien ons. = He sees us.

In Waar ontmoet ons?, ons is the subject, so it means we.

Yes. Ontmoet is the standard verb for to meet.

Examples:

• Ek ontmoet hom môre. = I meet him tomorrow / I am meeting him tomorrow.
• Ons ontmoet by die stasie. = We meet at the station.

Depending on context, it can mean meeting someone for the first time or meeting up with someone.

A simple learner-friendly guide:

• Waar sounds roughly like vahr
• ontmoet sounds roughly like ont-MOOT
• ons sounds roughly like ons in wants, but this varies by accent

A rough whole-sentence pronunciation:

• vahr ont-MOOT ons?

A few useful notes:

• w in Afrikaans is usually pronounced more like an English v
• oe in ontmoet sounds like oo in boot

Yes. Waar gaan ons ontmoet? is also correct, and it often sounds more like Where are we going to meet? or Where will we meet?

The difference is roughly:

• Waar ontmoet ons? = Where do we meet? / Where are we meeting?
• Waar gaan ons ontmoet? = Where are we going to meet?

The shorter sentence is perfectly natural, especially when the future meaning is clear from context.

It is neutral and natural. You can use it in everyday speech.

Afrikaans does not usually need different verb forms for formal and informal you here, because this sentence uses ons = we. So there is nothing especially formal or informal about it.

You would usually answer with a place.

Examples:

• Ons ontmoet by die kafee. = We meet at the café.
• By die stasie. = At the station.
• Ons ontmoet voor die winkel. = We meet in front of the shop.

So the question asks for the location of the meeting.
