Die dokument is kort en daarby duidelik.

Here daarby means besides that, in addition, or moreover.

So Die dokument is kort en daarby duidelik means something like:

• The document is short and also clear
• The document is short and, moreover, clear

It adds a slight sense of extra emphasis to the second adjective. It is not just listing two qualities; it is saying the second one is an added advantage.

Good question. They do slightly different jobs.

• en = and
• daarby = besides / moreover / in addition

So:

• kort en duidelik = short and clear
• kort en daarby duidelik = short and, besides that, clear

The version with daarby sounds a bit more expressive. It suggests that being clear is an extra positive feature.

Yes. That is completely natural Afrikaans.

• Die dokument is kort en duidelik = The document is short and clear

The original sentence with daarby is just a little more emphatic or polished. It highlights duidelik as an additional benefit.

Because one is can cover both adjectives.

In Afrikaans, just like in English, you can say:

• The document is short and clear
• Die dokument is kort en duidelik

You do not need to repeat the verb before the second adjective.

So Die dokument is kort en daarby duidelik is normal. The is applies to both kort and duidelik.

Because duidelik is being used after the verb is. In that position, Afrikaans normally uses the basic adjective form.

Compare:

• Die dokument is duidelik. = The document is clear.
• ’n duidelike dokument = a clear document

So:

• after is: duidelik
• before a noun: duidelike

The same applies to many Afrikaans adjectives.

Yes. Both kort and duidelik are adjectives describing die dokument.

Structure:

• Die dokument = the document
• is = is
• kort = short / brief
• en daarby duidelik = and moreover clear

So the sentence gives two descriptions of the document.

In a sentence about a document, kort usually means brief or not long.

So here it most naturally means the document is:

• not lengthy
• concise / brief

Afrikaans kort can refer to physical length too, but with dokument, the meaning brief is the usual one.

Die is the definite article, meaning the.

So:

• die dokument = the document

Unlike English, Afrikaans uses die for all grammatical genders, and also for plural definite nouns.

Examples:

• die boek = the book
• die tafel = the table
• die dokumente = the documents

Yes, completely normal.

The basic order is:

• Subject: Die dokument
• Verb: is
• Description: kort en daarby duidelik

This is standard Afrikaans main-clause word order.

Yes. Depending on context, daarby can have a more literal meaning like by it or with that, but in sentences like this it often means besides that or moreover.

So learners should pay attention to context.

In this sentence, the natural interpretation is the idiomatic one:

• moreover
• in addition

Sometimes, yes, but the nuance changes.

• ook = also / too
• daarby = besides that / moreover / in addition

Compare:

• Die dokument is kort en ook duidelik. = The document is short and also clear.
• Die dokument is kort en daarby duidelik. = The document is short and, moreover, clear.

Both are understandable, but daarby sounds a bit more formal or emphatic here.

It sounds mostly neutral to slightly formal, especially because of daarby.

If you want a simpler, everyday version, you might say:

• Die dokument is kort en duidelik.

The original version is still perfectly natural, but it has a slightly more polished tone.

Not normally in a simple sentence like this.

So this is fine:

• Die dokument is kort en daarby duidelik.

A comma could appear in some writing styles if the speaker wants to mark a pause, but it is not necessary here.
