Die kontraktydperk bepaal die installasiefooi.

Word by word:

• Die = the
• kontraktydperk = contract period or term of the contract
• bepaal = determines / decides / sets
• die = the
• installasiefooi = installation fee

A very literal translation is:

• The contract period determines the installation fee.

Because Afrikaans uses die as the definite article, meaning the.

So in this sentence:

• Die kontraktydperk = the contract period
• die installasiefooi = the installation fee

Unlike English, Afrikaans does not change the definite article for gender or case. It is simply die in most normal situations.

No. Afrikaans does not have grammatical gender the way languages like German or Dutch do.

So you do not need to learn different words for the depending on the noun.
For definite nouns, die is used regardless of gender.

That makes Afrikaans easier than many other European languages in this respect.

Yes, it is one word because Afrikaans, like Dutch and German, very often forms compound nouns by writing them together.

• kontrak = contract
• tydperk = period / term

Together:

• kontraktydperk = contract period

English often writes similar ideas as two words, but Afrikaans commonly joins them into one compound noun.

Yes.

It is made up of:

• installasie = installation
• fooi = fee

So:

• installasiefooi = installation fee

This is another very common Afrikaans pattern: two nouns join to form one more specific noun.

Because Afrikaans verbs are much simpler than English verbs.

In the present tense, the verb usually does not change depending on the subject:

• Ek bepaal = I determine
• Jy bepaal = you determine
• Hy bepaal = he determines
• Ons bepaal = we determine

So Afrikaans uses bepaal for all of these, while English changes to determines with he/she/it.

It follows the normal Subject–Verb–Object order:

• Die kontraktydperk = subject
• bepaal = verb
• die installasiefooi = object

So it works just like a basic English statement:

• The contract period / determines / the installation fee

This is the usual word order in a simple main clause in Afrikaans.

Yes. bepaal can mean several closely related things depending on context, such as:

• determine
• decide
• set
• establish

In this sentence, it suggests that the contract period is the factor that sets or determines the installation fee.

So depending on the context, an English speaker might also understand it as:

• The contract term sets the installation fee.

Afrikaans often uses ’n for a/an.

So if you wanted to say something like:

• A contract period determines an installation fee

you could say:

• ’n Kontraktydperk bepaal ’n installasiefooi.

A few useful notes:

• ’n is written with an apostrophe.
• It is not capitalized, even at the start of a sentence in normal writing conventions; the following word is capitalized instead.

A rough English-friendly guide is:

• Die ≈ dee
• kontraktydperk ≈ kon-TRAK-tate-perk
• bepaal ≈ buh-PAHL
• die ≈ dee
• installasiefooi ≈ in-stah-LAH-see-foy

A couple of helpful pronunciation points:

• aa in bepaal is a long a sound.
• fooi sounds roughly like foy.
• Stress often falls strongly in compounds, especially on important syllables like trak, tyd, and fooi.

Because Afrikaans does not capitalize all nouns.

Only the first word of the sentence and proper names are normally capitalized. So:

• Die kontraktydperk bepaal die installasiefooi.

Even though kontraktydperk and installasiefooi are nouns, they stay lowercase unless they begin the sentence.

Yes. The present tense in Afrikaans often works like the English present tense for:

• general truths
• policies
• standard procedures
• repeated situations

So this sentence can mean either:

• a general rule: The contract period determines the installation fee
• a specific current situation, depending on context

Afrikaans does not need a special form here to express that general idea.

The likely plurals are:

• kontraktydperk → kontraktydperke
• installasiefooi → installasiefooie

So, for example:

• Die kontraktydperke bepaal die installasiefooie.
• The contract periods determine the installation fees.

This is useful because Afrikaans plurals often appear in real-life administrative or business language.
