Die reiskoste is hoog.

Die is the definite article in Afrikaans, meaning the.

So die reiskoste means the travel cost or the travel costs, depending on context.

A useful thing to remember is that Afrikaans die does not change for gender or number. It can mean:

• the (singular)
• the (plural)

So unlike some other languages, you do not need different forms for masculine, feminine, neuter, or plural nouns.

This is a very common question, because koste looks plural to English speakers.

In Afrikaans, koste often functions like a collective or fixed noun meaning cost, costs, or expenses. In many cases, it is treated as a single idea, which is why the sentence uses is.

So in Die reiskoste is hoog, the phrase refers to the travel cost/expense as one overall thing.

You may think of it as:

• the travel cost is high
• or the travel expenses are high

Afrikaans often uses the singular verb here because the whole amount is being viewed as one total.

Because Afrikaans uses is as the present tense form of to be for all persons and numbers.

Examples:

• Ek is — I am
• Jy is — you are
• Hy is — he is
• Ons is — we are
• Hulle is — they are

So even if a noun feels plural in English, the verb form itself does not change. Afrikaans does not have separate present-tense forms like am / is / are.

Reiskoste is a compound noun:

• reis = travel, trip, journey
• koste = cost, costs, expenses

Afrikaans forms compounds very freely, much like Dutch and German. Instead of writing separate words, Afrikaans often combines them into one word.

So:

• reis + koste = reiskoste

This is very normal in Afrikaans. English often writes similar ideas as two words, but Afrikaans usually prefers one compound word.

Yes. Die koste van die reis is hoog is also correct.

That version is more literally the cost of the trip is high.

The difference is mostly style:

• die reiskoste = more compact, compound-noun style
• die koste van die reis = more expanded and explicit

Afrikaans often prefers compounds when they are natural and common.

Because predicate adjectives in Afrikaans usually stay in their basic form after a linking verb like is.

In this sentence:

• Die reiskoste = subject
• is = linking verb
• hoog = adjective describing the subject

So hoog means high, and it does not need an ending here.

Compare:

• Die reiskoste is hoog. — The travel cost is high.

But when an adjective comes before a noun, Afrikaans often adds -e:

• die hoë reiskoste — the high travel cost

So the difference is:

• after is: hoog
• before a noun: often hoë

The sentence follows the basic Afrikaans main-clause word order:

Subject + verb + complement

So:

• Die reiskoste = subject
• is = verb
• hoog = complement/adjective

This is very similar to English:

• The travel cost is high

So for an English speaker, the structure here is straightforward and familiar.

A simple pronunciation guide for English speakers:

• reis sounds roughly like race but with a slightly different vowel quality depending on accent
• koste sounds roughly like KOS-tuh
• hoog sounds roughly like hohkh or hawkh, with the final g made in the back of the throat

A few useful notes:

• The g in Afrikaans is usually not like English g in go. It is usually a rough throat sound.
• oo in hoog is a long vowel.
• Stress in reiskoste is usually on the first part: REIS-koste

If you are aiming for clear beginner pronunciation, saying REIS-kos-te is hoog with a distinct throat sound on g is a good start.

It can also describe things like prices, costs, numbers, or levels.

So hoog does not only mean tall or high in a physical sense. It can also mean:

• high prices
• high costs
• high numbers
• high levels

That is why Die reiskoste is hoog is perfectly natural for saying the travel cost is expensive or high.

Yes, it is perfectly natural, especially in neutral or formal contexts.

You might see or hear it in:

• business communication
• travel planning
• budgeting
• written notices
• formal conversation

In everyday speech, people might also use slightly different wording depending on the situation, such as talking about reisuitgawes or die koste van die reis, but Die reiskoste is hoog is completely standard and idiomatic.

The negative is:

Die reiskoste is nie hoog nie.

Afrikaans usually uses double negation, so you get:

• is nie before the adjective
• another nie at the end

Structure:

• Die reiskoste = subject
• is nie = is not
• hoog = high
• nie = final negative marker

This is one of the most important grammar patterns in Afrikaans.
