Die vlak is hoog.

Here, die is the definite article, so it usually means the.

A useful thing for learners is that Afrikaans uses die much more simply than some other European languages:

• no grammatical gender distinction
• no case endings
• the same die is also used with plural nouns

So you get:

• die boek = the book
• die tafel = the table
• die kinders = the children

It is capitalized only because it is the first word of the sentence.

Afrikaans does not capitalize all nouns the way German does. So in the middle of a sentence, you would write:

• die vlak is hoog

not because vlak is less important, but simply because normal noun capitalization rules are different.

In Die vlak is hoog, vlak is a noun. It is the subject of the sentence.

You can tell because it comes after the article die, which strongly suggests a noun phrase:

• die vlak = the level / the plain / the surface / etc., depending on context

The describing word in the sentence is hoog, which is the adjective.

Because this is a normal simple main clause in Afrikaans:

• subject
  • verb
    • complement

So:

• Die vlak = subject
• is = verb
• hoog = complement/adjective

This is very similar to English: The level is high.

It also fits the Afrikaans verb-second pattern: the finite verb usually comes in the second position in a main clause. Since Die vlak is the first element, is comes second.

Because hoog comes after the verb is. In that position, Afrikaans adjectives usually stay in their basic form.

Compare:

• Die vlak is hoog. = adjective after the verb
• die hoë vlak = adjective before the noun

So the form often changes when the adjective stands directly in front of a noun, but not when it comes after is.

A rough guide:

• h sounds like English h
• oo is a long vowel
• the final g is a guttural sound, like the ch in Scottish loch or German Bach

So the last sound is not the English g of go.

If that final sound is hard at first, that is normal. Many English speakers need practice with Afrikaans g.

You would say:

Die vlak is nie hoog nie.

Afrikaans commonly uses a double nie pattern in full sentence negation:

• first nie after the verb phrase or the part being negated
• second nie at the end of the clause

So:

• Die vlak is hoog. = The level is high.
• Die vlak is nie hoog nie. = The level is not high.

You would use the indefinite article 'n:

'n vlak is hoog.

A few important points:

• 'n means a / an
• it is always written with a small n
• if it comes at the beginning of a sentence, the next word is capitalized instead

So at the start of a sentence, you write:

• 'n Vlak is hoog.

not 'N vlak is hoog.

The plural is vlakke.

So:

• Die vlak is hoog. = The level is high.
• Die vlakke is hoog. = The levels are high.

Notice that the article for the plural definite form is still die.

Yes. Like many Afrikaans words, vlak can have different English translations depending on context.

That means the exact translation may change, but the grammar of the sentence stays the same:

• die
  • noun + is
    • adjective

So once the context tells you what vlak refers to, the sentence structure is still straightforward.
