Volgens die dokument is hierdie antwoord duidelik.

This is a very common Afrikaans word-order question.

Afrikaans is a verb-second (V2) language in main clauses. That means the finite verb usually comes in the second position of the sentence.

In this sentence:

Volgens die dokument | is | hierdie antwoord duidelik

• Volgens die dokument is the first element.
• So the verb is must come next.
• Then the subject hierdie antwoord follows.

If you start with the subject instead, you get:

Hierdie antwoord is volgens die dokument duidelik.

That is also grammatical, but the emphasis is slightly different.

So the sentence structure is normal Afrikaans:

• first element: Volgens die dokument
• second position: is
• then the rest of the sentence

Volgens usually means according to.

So:

• Volgens die dokument = According to the document

It is used to introduce a source of information, opinion, or authority.

Examples:

• Volgens die onderwyser is dit reg.
  = According to the teacher, this is correct.
• Volgens die nuus gaan dit reën.
  = According to the news, it is going to rain.

A useful thing to notice is that volgens is followed directly by a noun phrase:

• volgens die dokument
• volgens hom
• volgens my

Die is the normal Afrikaans definite article, meaning the.

So:

• die dokument = the document

Afrikaans does not distinguish between the for masculine, feminine, or neuter nouns. It is simply die for all of them.

Examples:

• die boek = the book
• die tafel = the table
• die man = the man

So in this sentence, die dokument just means the document.

They are doing different jobs:

• die dokument = the document
• hierdie antwoord = this answer

So:

• die = the
• hierdie = this

Hierdie is a demonstrative, used to point something out as being near or relevant in context.

Compare:

• hierdie antwoord = this answer
• daardie antwoord = that answer
• die antwoord = the answer

For an English speaker, it helps to think:

• die = definite article
• hierdie / daardie = demonstratives

Because antwoord is just the noun answer, and Afrikaans nouns usually do not change form for this kind of use.

In English, we also say:

• this answer
• not this answered or anything similar

Afrikaans works the same way here:

• hierdie antwoord = this answer

Also, Afrikaans nouns do not change for grammatical gender, and they generally do not change form after demonstratives.

This is an excellent question because Afrikaans adjectives behave differently depending on where they appear.

In your sentence, duidelik comes after the verb is:

• Hierdie antwoord is duidelik.

Here it is a predicative adjective, and in that position Afrikaans normally uses the basic form:

• duidelik = clear

But when the adjective comes before a noun, it often takes -e:

• 'n duidelike antwoord = a clear answer

So compare:

• Die antwoord is duidelik.
  predicative adjective
• Dit is 'n duidelike antwoord.
  attributive adjective

That is why the sentence uses duidelik, not duidelike.

Yes. The subject is hierdie antwoord.

Even though it comes after the verb, it is still the subject.

The sentence is basically:

• Volgens die dokument = according to the document
• is = is
• hierdie antwoord = this answer
• duidelik = clear

So the core statement is:

Hierdie antwoord is duidelik.
= This answer is clear.

The phrase Volgens die dokument is extra information placed at the front.

Yes, that is possible.

Both are grammatical:

• Volgens die dokument is hierdie antwoord duidelik.
• Hierdie antwoord is volgens die dokument duidelik.

The difference is mainly one of focus or emphasis.

• Starting with Volgens die dokument puts emphasis on the source.
• Starting with Hierdie antwoord puts emphasis on the answer itself.

Afrikaans often moves elements to the front for emphasis, but the finite verb still stays in second position in a main clause.

Yes. Is is the present-tense form of wees (to be), and here it works as a linking verb.

It links:

• the subject: hierdie antwoord
• to the description: duidelik

So the structure is like:

• This answer
  • is
    • clear

This is very similar to English.

Also note that Afrikaans does not usually use do-support the way English does. So simple present linking sentences are very straightforward:

• Dit is goed.
• Hy is moeg.
• Die antwoord is duidelik.

Yes, but the meaning changes slightly.

Compare:

• hierdie antwoord = this answer
• daardie antwoord = that answer
• die antwoord = the answer

So you could say:

• Volgens die dokument is die antwoord duidelik.
• Volgens die dokument is daardie antwoord duidelik.

Each version is grammatical, but the demonstrative choice changes how specifically you point to the answer.

Use:

• hierdie when something is close, current, or immediately relevant
• daardie when it is more distant
• die when you just mean the

Usually, no comma is necessary in normal Afrikaans spelling:

• Volgens die dokument is hierdie antwoord duidelik.

A comma might sometimes appear for stylistic reasons, but it is not the standard requirement here.

So for a learner, the safest version is:

Volgens die dokument is hierdie antwoord duidelik.

A helpful breakdown is:

• Volgens = according to
• die = the
• dokument = document
• is = is
• hierdie = this
• antwoord = answer
• duidelik = clear

So the structure is very transparent once you know the word order rule.

A natural English-style gloss would be:

According to the document, this answer is clear.

It sounds neutral to slightly formal.

That is mainly because of:

• Volgens die dokument = a fairly formal way to refer to a source
• duidelik = standard, neutral vocabulary

It would fit well in:

• schoolwork
• reports
• official communication
• careful spoken Afrikaans

It is not overly stiff, but it is more formal than something very conversational.
