Die merker is swart.

Yes. In this sentence, die means the.

Afrikaans uses die as the definite article for singular and plural nouns:

• die merker = the marker
• die merkers = the markers

Unlike English, Afrikaans does not change the word the based on gender or case.

Merker means marker, as in a pen-like writing tool.

It is a straightforward cognate for English speakers because it looks and sounds similar to marker. In everyday Afrikaans, people may also use other words depending on the exact object, but merker is perfectly understandable.

This is the normal basic word order for a simple statement in Afrikaans:

subject + verb + complement

So:

• Die merker = subject
• is = verb
• swart = adjective/complement

That makes:

• Die merker is swart. = The marker is black.

This is very similar to English word order.

Yes. Is is the Afrikaans present-tense form of the verb to be in this sentence, and it works very much like English is.

Examples:

• Die merker is swart. = The marker is black.
• Die boek is nuut. = The book is new.

A useful point for learners: Afrikaans verbs usually change much less than English verbs. Is stays is where English also uses is.

In this sentence, swart comes after the verb is, so it is being used predicatively. In that position, Afrikaans adjectives usually do not change.

So:

• Die merker is swart. = The marker is black.

Compare that with an adjective before a noun, where Afrikaans often adds -e:

• die swart merker = the black marker

So the difference is:

• after is: swart
• before the noun: often swart or swart(e) depending on the word and pattern, but very commonly swart remains unchanged in practice with many learners' early examples

For this sentence, the important thing is: after is, swart stays swart.

No, not in standard Afrikaans.

Afrikaans die is usually pronounced roughly like dee.

So:

• die ≈ dee
• not like English die /dai/

This is one of the first pronunciation differences English speakers need to learn.

Swart is pronounced roughly like svahrt.

A few helpful notes:

• sw is pronounced with a clear s sound followed by v/w-like rounding depending on accent
• the vowel is broad, closer to a in father than the English vowel in black
• the r is pronounced
• the t at the end is also pronounced

You do not pronounce it like English swart would be read.

Yes. It is a complete, natural Afrikaans sentence.

It has:

• a subject: Die merker
• a verb: is
• a description: swart

So it fully expresses one idea: the marker has the color black.

Afrikaans does not use grammatical gender in the same way languages like German or Dutch do.

So you do not need to learn separate articles like masculine/feminine/neuter for most everyday Afrikaans usage. You simply use die for the.

That makes sentences like Die merker is swart much simpler for English speakers than equivalent sentences in some other European languages.

Afrikaans usually uses a double negative with nie ... nie.

So:

• Die merker is swart. = The marker is black.
• Die merker is nie swart nie. = The marker is not black.

This double nie pattern is one of the most important grammar features in Afrikaans.

In Afrikaans, yes/no questions often put the verb first.

So:

• Die merker is swart. = The marker is black.
• Is die merker swart? = Is the marker black?

This is very similar to English inversion:

• It is black.
• Is it black?

You would use ’n for a/an:

• ’n merker is swart. = A marker is black.

A useful pronunciation note:

• ’n is usually pronounced as a very weak neutral vowel, roughly like uh or ə
• it is written with an apostrophe: ’n

So:

• die merker = the marker
• ’n merker = a marker
