Die kinders eet hul kos klaar.

Here klaar shows completion. It tells you that the children do not just eat their food; they finish it or eat it all up.

So eet ... klaar is often very close to English finish eating or eat up.

That is normal Afrikaans word order here.

In a basic main clause, the finite verb usually comes early, and words like klaar often appear later in the clause, after the object:

• Die kinders = subject
• eet = verb
• hul kos = object
• klaar = completion word

So Die kinders eet hul kos klaar sounds natural.

Hul is the possessive form meaning their when it comes before a noun:

• hul kos = their food

By contrast, hulle is usually the independent pronoun:

• Hulle eet = They eat
• Ek sien hulle = I see them

In everyday speech, many people do also say hulle kos, but learners will often see hul kos in more careful or standard writing.

Because hul already does the job of a determiner.

Just like English says their food, not the their food, Afrikaans says:

• hul kos

not

• die hul kos

So a possessive word like hul, my, jou, ons, etc. normally replaces the article.

Yes. Afrikaans uses die for the with both singular and plural nouns.

So:

• die kind = the child
• die kinders = the children

Afrikaans does not change the definite article for gender or number the way some other European languages do.

The plural form here is kinders, from singular kind.

• kind = child
• kinders = children

This is just the normal plural form of this word, and you learn it as a vocabulary item. It corresponds to English child/children, where the plural is also not formed in the most regular way.

Because Afrikaans verbs usually do not change according to person or number in the present tense.

So you get:

• ek eet
• jy eet
• hy eet
• ons eet
• hulle eet

The form eet stays the same. That is much simpler than English, where you have eat but he eats.

Kos usually means food or sometimes a meal in a general sense.

In this sentence, hul kos means their food. It is a very common everyday Afrikaans word.

Depending on context, kos can refer to food in general, not necessarily one specific dish.

Yes. Klaar is a very common word and can mean things like finished, done, or ready, depending on context.

For example:

• Ek is klaar. = I am finished / I’m done.
• Die kos is klaar. = The food is ready.

But in eet hul kos klaar, it is not simply describing a state. It is helping show that the action of eating is completed.

Yes, that is a very helpful way to think about it.

English often uses eat up to show completion. Afrikaans can use eet ... klaar in a similar way. It gives the sense that the food gets completely eaten, not just partly eaten.
