Ons het ekstra tyd.

The sentence breaks down like this:

• Ons = we
• het = have
• ekstra = extra
• tyd = time

So the structure is:

• subject: Ons
• verb: het
• object / thing possessed: ekstra tyd

It follows the same basic order as English: We have extra time.

Yes. In Afrikaans, ons can mean both we and us.

English distinguishes:

• we = subject
• us = object

Afrikaans often does not make that distinction here:

• Ons het ekstra tyd. = We have extra time.
• Hy sien ons. = He sees us.

So you figure it out from word order and context.

Because hê is the infinitive form, meaning to have, while het is the finite form used in normal present-tense sentences.

Compare:

• Ek wil ekstra tyd hê. = I want to have extra time.
• Ons het ekstra tyd. = We have extra time.

So after the subject in a normal statement, you use het, not hê.

No. Afrikaans verbs usually do not change much for person, and het stays the same with all subjects:

• Ek het = I have
• Jy het = you have
• Hy/Sy het = he/she has
• Ons het = we have
• Julle het = you all have
• Hulle het = they have

So unlike English, you do not need a special has form.

Because tyd here is being used as an uncountable noun, just like time in English.

You say:

• We have extra time not
• We have an extra time

Likewise in Afrikaans:

• Ons het ekstra tyd

If you were talking about a specific unit or occasion, the wording would be different.

They are close, but not always identical.

• ekstra tyd = extra / additional time
• meer tyd = more time

Ekstra tyd often suggests something added beyond what was expected or planned.

Examples:

• Ons het ekstra tyd. = We have some additional time.
• Ons het meer tyd nodig. = We need more time.

So in many situations they can overlap, but ekstra emphasizes additional time.

Because this is a simple main clause, and Afrikaans often uses the same basic order as English in that kind of sentence:

• subject + verb + rest

So:

• Ons
  • het
    • ekstra tyd

However, Afrikaans word order changes in other situations, especially in questions and subordinate clauses.

For example:

• Het ons ekstra tyd? = Do we have extra time?
• ... omdat ons ekstra tyd het = ... because we have extra time

That final het in the subordinate clause is a very important Afrikaans pattern.

You usually make a yes/no question by inverting the subject and verb:

• Ons het ekstra tyd. = We have extra time.
• Het ons ekstra tyd? = Do we have extra time?

Notice that Afrikaans does not need a separate do the way English does.

Standard Afrikaans normally uses a double negative with nie ... nie.

So:

• Ons het ekstra tyd. = We have extra time.
• Ons het nie ekstra tyd nie. = We do not have extra time.

This double nie pattern is one of the most distinctive features of Afrikaans.

It can be plural, but not in this sentence.

• tyd = time
• tye = times / periods / occasions

In Ons het ekstra tyd, the singular form is natural because time is being treated as an uncountable amount.

You would use tye in contexts like:

• in moeilike tye = in difficult times

So here, tyd is definitely the right form.

A few things:

1. ons can mean both we and us
2. het means have, even though the infinitive is hê
3. There is no has form
4. Afrikaans does not use do in questions
5. Negatives use nie ... nie

So even though the sentence looks simple, it introduces several very common Afrikaans patterns.
