Die koste is duidelik.

Here, die is the Afrikaans definite article, meaning the.

A useful thing for English speakers to know is that Afrikaans uses die for:

• singular nouns
• plural nouns
• all genders

So unlike English, where you only have the, Afrikaans also has just one main definite article in everyday use: die.

No. In Afrikaans, die is usually pronounced more like dee.

So in this sentence:

• die = dee
• not the English die meaning “to stop living”

That is a very common beginner confusion.

Koste is a noun. It means cost, costs, or expenses, depending on context.

Because you already know the sentence meaning, the main thing to notice is that koste is the thing being talked about—the subject of the sentence.

It often refers to costs/expenses, so it can feel plural in English. But in Afrikaans, the form is does not help you decide, because is is used with both singular and plural subjects.

For example:

• Die koste is hoog. = The costs are high / The cost is high
• Die kinders is hier. = The children are here

So whether koste is understood as cost or costs depends mostly on context and on the translation you were given.

Because Afrikaans and English are related Germanic languages, some words look very familiar. Is is one of them.

But the important grammar point is this: in Afrikaans, is is used much more broadly than English is.

English:

• I am
• you are
• he is
• they are

Afrikaans:

• ek is
• jy is
• hy is
• ons is
• hulle is

So is does not change according to the subject.

Duidelik is an adjective here, meaning something like clear, obvious, or plain depending on context.

In Die koste is duidelik, it comes after is and describes die koste.

So the structure is:

• Die koste = the subject
• is = the verb
• duidelik = the description

This is very similar to English:

• The cost is clear.

Because in this sentence, duidelik is not directly in front of the noun. It is being used as a predicate adjective—an adjective that comes after a linking verb like is.

Compare:

• Die koste is duidelik.
  = The cost is clear.

But if you wanted to say the clear cost, Afrikaans would place the adjective before the noun:

• die duidelike koste

So:

• after is → duidelik
• before the noun → usually duidelike

This is a very common learner question.

In Afrikaans, adjectives often have:

• a basic form: duidelik
• an inflected form: duidelike

You usually use duidelik when the adjective comes after a linking verb:

• Die antwoord is duidelik.

You usually use duidelike when the adjective comes directly before the noun:

• die duidelike antwoord

So in your sentence, duidelik is correct because it comes after is.

Yes, very much so.

The sentence follows a simple pattern:

• Die koste = subject
• is = verb
• duidelik = complement/adjective

So it matches the English order:

• The cost is clear.

This is one reason simple Afrikaans sentences can feel approachable to English speakers.

Not in the way languages like German or French do.

For a learner, one helpful feature of Afrikaans is that you do not have to memorize noun gender for articles like:

• masculine
• feminine
• neuter

That is why die is so useful—it works broadly without gender changes.

A rough English-friendly guide would be:

dee KOS-tuh is DUY-duh-lik

Very roughly:

• Die → dee
• koste → KOS-tuh
• is → is
• duidelik → something like DUY-duh-lik

The exact pronunciation varies by speaker and accent, but that approximation is good enough for a beginner.

Yes. This is a very useful basic pattern in Afrikaans:

Die + noun + is + adjective

For example:

• Die huis is groot. = The house is big.
• Die water is koud. = The water is cold.
• Die antwoord is reg. = The answer is correct.
• Die probleem is ernstig. = The problem is serious.

So Die koste is duidelik is a good model sentence to learn from.

Probably these three points:

1. die = the for basically all nouns
2. is stays is regardless of subject number/person
3. Adjectives after is usually stay in their basic form, like duidelik

So this sentence is a good example of a very common Afrikaans structure: article + noun + is + adjective
