Die opwarmroetine berei die rotsklimmer voor.

Because die is the Afrikaans definite article, meaning the. It is used for both the warm-up routine and the rock climber.

A few useful points:

• die does not change for gender
• it is also used for singular and plural in many contexts
• Die at the beginning is capitalized only because it starts the sentence

So:

• Die opwarmroetine = the warm-up routine
• die rotsklimmer = the rock climber

Afrikaans very often forms compound nouns by writing them as a single word.

So opwarmroetine is a compound:

• opwarm = warm up
• roetine = routine

Together, opwarmroetine means warm-up routine.

This is very normal in Afrikaans. English often writes these as two words or hyphenates them, but Afrikaans prefers one compound word.

This is one of the most important grammar points in the sentence.

The full verb is voorberei, meaning to prepare. In a main clause, Afrikaans often splits certain verbs into:

• the verb stem in the normal verb position
• the particle at the end

So:

• voorberei → berei ... voor

That is why you get:

• Die opwarmroetine berei die rotsklimmer voor.

This is called a separable verb pattern.

Compare:

• infinitive: om die rotsklimmer voor te berei
• main clause: Die opwarmroetine berei die rotsklimmer voor

Because with a separable verb like voorberei, the sentence often places other elements between the two parts of the verb.

Structure here:

• Die opwarmroetine = subject
• berei = first part of the verb
• die rotsklimmer = object
• voor = separable particle

So the pattern is:

Subject + verb + object + particle

That is completely normal in Afrikaans main clauses.

Yes. rotsklimmer is another compound noun.

It is made from:

• rots = rock
• klimmer = climber

So rotsklimmer means rock climber.

Afrikaans uses compound nouns very freely, so learners will see this kind of structure a lot.

Usually, no. Afrikaans verbs are much simpler than English verbs in this respect.

For the present tense, the verb usually stays the same regardless of the subject:

• Ek berei voor
• Jy berei voor
• Hy/Sy berei voor
• Ons berei voor
• Hulle berei voor

So unlike English, you do not get a special -s form like prepares.

That makes Afrikaans verb conjugation much easier for English speakers.

It is in the present tense.

Die opwarmroetine berei die rotsklimmer voor can mean something like:

• the warm-up routine prepares the rock climber
• the warm-up routine is preparing the rock climber

In many cases, the present tense in Afrikaans can express:

• a general truth
• a habitual action
• something happening now, depending on context

The unsplit form is voorberei.

You usually see the unsplit form in places like:

• the infinitive
• subordinate clauses
• past participle constructions in some contexts

For example:

• om die rotsklimmer voor te berei = to prepare the rock climber
• ... dat die opwarmroetine die rotsklimmer voorberei = ... that the warm-up routine prepares the rock climber

So in a main clause, you often get berei ... voor, but in other structures you may see voorberei as one unit.

Because Afrikaans does not need an extra helper word here.

English often uses helper verbs such as:

• does prepare
• is preparing

Afrikaans can simply use the present tense verb:

• berei ... voor

So the sentence is complete without adding anything like is or does.

No, not in the way you would in languages like German.

Afrikaans is much simpler here:

• nouns do not change for grammatical case
• articles do not change for masculine/feminine/neuter gender
• adjectives are also much less complicated than in many European languages

That is why both noun phrases just use die:

• Die opwarmroetine
• die rotsklimmer

A rough English-friendly guide would be:

duh OP-varm-roy-TEE-nuh buh-RAY dye ROTS-klim-er for

A few notes:

• die sounds like duh in Afrikaans, not like English die
• berei sounds roughly like buh-RAY
• voor sounds like for or foor, depending on accent
• g and r in Afrikaans can sound stronger than in English

This is only an approximation, but it helps avoid the most common beginner mistake: pronouncing die like the English verb die.
