Die hitte-uitputting en dehidrasie is gevaarlik.

Die is the Afrikaans definite article, meaning the.

In this sentence, Die hitte-uitputting en dehidrasie means the heat exhaustion and dehydration.

A few useful points:

• die is used for all genders in Afrikaans
• it can also be used with plural nouns
• it is capitalized here only because it is the first word of the sentence

So in the middle of a sentence, you would normally write die, not Die.

Afrikaans, like English, can use one definite article for two nouns joined by en if both are being grouped together.

So:

• Die hitte-uitputting en dehidrasie = the heat exhaustion and dehydration

This is similar to English saying:

• the heat exhaustion and dehydration

You could sometimes repeat the article for emphasis or clarity, but it is often unnecessary.

Hitte-uitputting literally breaks down as:

• hitte = heat
• uitputting = exhaustion

So the word means heat exhaustion.

The hyphen is there because Afrikaans often uses hyphens in compound words in certain cases, especially when it helps readability. Compound nouns are very common in Afrikaans, and English speakers often notice that Afrikaans likes to build long noun combinations this way.

So hitte-uitputting is one combined idea: exhaustion caused by heat.

Yes, it is a very close cognate.

• dehidrasie = dehydration

Many academic, medical, and technical words in Afrikaans look similar to English because they come from related international roots.

That means words like this are often easier to recognize, even if the spelling is slightly different.

En means and.

So:

• hitte-uitputting en dehidrasie = heat exhaustion and dehydration

It works just like English and in this sentence.

This is a very important Afrikaans grammar point: Afrikaans verbs usually do not change form according to the subject.

So is is used with:

• ek is = I am
• jy is = you are
• hy is = he is
• ons is = we are
• hulle is = they are

That means is can correspond to both is and are in English.

So in this sentence:

• Die hitte-uitputting en dehidrasie is gevaarlik
• literally: The heat exhaustion and dehydration is dangerous
• natural English: Heat exhaustion and dehydration are dangerous

The Afrikaans is completely normal.

Gevaarlik means dangerous.

So the last part of the sentence:

• is gevaarlik = is dangerous / are dangerous

It comes from gevaar, which means danger.

Because here the adjective comes after the verb is.

In Afrikaans, adjectives often have different forms depending on where they appear:

• predicative position, after a verb like is: usually no -e
• attributive position, before a noun: often -e

So:

• Die hitte-uitputting is gevaarlik = The heat exhaustion is dangerous
• die gevaarlike toestand = the dangerous condition

In your sentence, gevaarlik is correct because it follows is.

Yes. The sentence follows a very familiar pattern:

• Subject: Die hitte-uitputting en dehidrasie
• Verb: is
• Adjective/complement: gevaarlik

So it matches the English structure quite closely:

• Heat exhaustion and dehydration are dangerous

That makes this sentence fairly easy for English speakers to understand.

A very literal word-for-word rendering would be:

• The heat-exhaustion and dehydration is dangerous

But that is not natural English, mainly because English changes is to are with a plural subject.

A natural English translation is:

• Heat exhaustion and dehydration are dangerous
• or Heat exhaustion and dehydration are dangerous conditions

So the literal version helps you see the structure, but the natural translation is what you would actually say in English.

A rough English-friendly guide:

• Die: roughly like dee
• hitte: roughly HIT-uh
• uitputting: roughly ATE-puh-ting or OYT-puh-ting, depending on how carefully you want to approximate the Afrikaans ui
• dehidrasie: roughly dee-hee-DRAH-see
• gevaarlik: roughly khuh-VAHR-lik or guh-VAHR-lik, depending on accent and how you handle the Afrikaans g

A few pronunciation notes:

• Afrikaans g is usually a harsher sound than English g
• the ui sound in Afrikaans is not exactly like any single English vowel
• stress in gevaarlik falls on vaar

If you are learning pronunciation, gevaarlik and uitputting are probably the trickiest words in this sentence.

Yes. That would mean:

• Heat exhaustion and dehydration are very dangerous

Here, baie means very.

So:

• gevaarlik = dangerous
• baie gevaarlik = very dangerous

That is a very natural way to strengthen the sentence.

This sentence is useful because it shows several core Afrikaans patterns at once:

1. die = the
2. en = and
3. is stays the same even where English would use are
4. adjectives after is usually stay in their basic form, like gevaarlik
5. Afrikaans often uses compounds such as hitte-uitputting

So even though the sentence is short, it teaches some very typical Afrikaans grammar.
