In hierdie verband is die tarief duidelik.

This is because Afrikaans follows a verb-second pattern in main clauses.

• The sentence begins with In hierdie verband.
• Since that element is placed first, the finite verb is must come next.
• The subject die tarief then comes after the verb.

So the structure is:

• In hierdie verband = first element
• is = second element (the verb)
• die tarief = subject
• duidelik = complement

If you started with the subject instead, you could also say:

• Die tarief is in hierdie verband duidelik.

That is grammatical too, but the original sentence gives extra emphasis to In hierdie verband.

In hierdie verband usually means:

• In this connection
• In this regard
• In this context

The noun verband literally has the idea of a connection or relation, but in this fixed expression it is best understood idiomatically as regard or context.

So learners should usually treat In hierdie verband as a set phrase.

They do different jobs:

• hierdie = this
• die = the

So:

• hierdie verband = this context / this regard
• die tarief = the rate / the tariff

A useful way to see it:

• hierdie points something out specifically, like English this
• die is the normal definite article, like English the

On its own, verband can mean something like:

• connection
• relation
• context

In some contexts it can also mean bandage, so the word has more than one meaning depending on usage. But in the expression in hierdie verband, it definitely means something like in this connection/regard.

So in this sentence, you should not think of the medical meaning.

Tarief usually means:

• rate
• tariff
• sometimes fee or charge, depending on context

The exact English translation depends on what kind of text this comes from:

• in business or utilities: rate
• in customs or trade: tariff
• in pricing or billing: sometimes fee/charge

So the Afrikaans word is slightly broader than one single English word.

Because duidelik is being used as a predicate adjective, not an adjective directly before a noun.

Here it comes after is:

• die tarief is duidelik = the rate is clear

In this position, Afrikaans usually uses the basic adjective form:

• duidelik

But before a noun, you would usually use the inflected form:

• die duidelike tarief = the clear rate / the clearly defined tariff

So:

• after is -> duidelik
• before a noun -> duidelike

You can get close, but a fully natural English translation is usually more idiomatic.

Word-for-word:

• In = in
• hierdie = this
• verband = connection/regard
• is = is
• die = the
• tarief = rate/tariff
• duidelik = clear

A very literal version would be:

• In this regard, the rate is clear.

That works well in English. But depending on context, a translator might also choose:

• In this context, the tariff is clear.
• On this point, the rate is clear.

So the sentence can be translated quite directly, but the best choice depends on context.

Yes. In dié verband is also correct.

Here, dié is a stressed form of die, often used to mean something like:

• that particular
• this specific

In practice:

• In hierdie verband = in this regard
• In dié verband = in this regard / in that particular regard

The difference is often subtle. Hierdie is very straightforward for learners and clearly means this.

A rough English-friendly pronunciation is:

• In hierdie verband is die tarief duidelik
• in HEER-dee fer-BAHNT is dee ta-REEF DOY-duh-lik

A few notes:

• g in Afrikaans is usually a harsher sound than in English.
• die is pronounced roughly like dee, not like English die.
• duidelik begins with a sound roughly like doy.

This is only an approximation, but it helps avoid the most common mistakes.

Yes. A more straightforward subject-first version would be:

• Die tarief is in hierdie verband duidelik.

Both are grammatical, but they differ in focus:

• In hierdie verband is die tarief duidelik.
  Emphasizes in this regard / in this context.

• Die tarief is in hierdie verband duidelik.
  Starts more neutrally with the rate.

So the original sentence is not unusual; it just gives prominence to the opening phrase.
