Die kragopwekker lewer rugsteunkrag.

It follows the normal Afrikaans main-clause order:

subject + verb + object

• Die kragopwekker = the subject
• lewer = the verb
• rugsteunkrag = the object

So it works just like English The generator supplies backup power.

Die is the definite article in Afrikaans, usually meaning the.

So:

• die kragopwekker = the generator

A useful thing to know is that Afrikaans does not have grammatical gender like German or Dutch. You do not have to learn different forms like de/het or der/die/das. In Afrikaans, die is used very broadly for definite nouns.

Because rugsteunkrag is being used as an uncountable or general noun, like English backup power.

Compare:

• Die kragopwekker lewer rugsteunkrag. = The generator supplies backup power.
• Die kragopwekker lewer die rugsteunkrag. = The generator supplies the backup power.

The version without die sounds more general and is the natural choice here.

Yes. Afrikaans very often writes compound nouns as a single word.

kragopwekker is a compound noun:

• krag = power
• opwek = generate / produce
• -er = a thing or person that does something

So kragopwekker literally means something like power-generator, which English normally writes as generator.

Here lewer is a verb meaning deliver, provide, or supply.

In this sentence, supplies is the most natural English translation:

• Die kragopwekker lewer rugsteunkrag.
• The generator supplies backup power.

Be aware that lewer can also be a noun meaning liver, but in this sentence it is clearly a verb because of its position and function.

No. Afrikaans verbs usually do not change according to the subject in the present tense.

So you get:

• Ek lewer = I supply
• Jy lewer = you supply
• Die kragopwekker lewer = the generator supplies
• Hulle lewer = they supply

This is much simpler than English, where you have I supply but he supplies.

Rugsteunkrag is another compound noun:

• rugsteun = backup / support
• krag = power

So rugsteunkrag means backup power.

Afrikaans often combines ideas into one word where English may use two words.

Normally, no. In standard Afrikaans, this idea is written as the compound noun rugsteunkrag.

Writing it as two words would usually look unnatural or incorrect in ordinary spelling.

A rough English-friendly guide would be:

• kragopwekker ≈ khrahkh-op-VEK-er
• rugsteunkrag ≈ ruhk-STAYN-khrahkh

A few pronunciation notes:

• g in Afrikaans is often a harsh throat sound, not the soft English g
• w is usually like English v
• eu in steun is not an exact English sound, but something like the vowel in Dutch leuk or a rounded version of ay

If you want to sound more natural, listening to native audio is especially helpful for words with g and eu.

Because lewer is the main verb here, and it already expresses the action: supplies or provides.

This is not a sentence like:

• Die kragopwekker is groot. = The generator is big.

Instead, it is an action sentence:

• Die kragopwekker lewer rugsteunkrag. = The generator supplies backup power.

So no extra verb like is is needed.

Yes.

For kragopwekker, Afrikaans speakers may also use:

• generator

For lewer, possible alternatives depend on context:

• verskaf = provide
• sometimes voorsien van = provide with

But in this sentence, lewer rugsteunkrag sounds very natural and idiomatic.

The plural is usually:

• kragopwekkers = generators

So:

• Die kragopwekkers lewer rugsteunkrag.
• The generators supply backup power.

This is a useful pattern because many Afrikaans nouns form the plural with -s or -e, though you still need to learn the normal plural form for each word.

Afrikaans commonly uses het + past participle.

So you would say:

• Die kragopwekker het rugsteunkrag gelewer.
• The generator supplied backup power.

Notice two things:

• het is the auxiliary verb
• gelewer is the past participle of lewer

Also notice the word order: in a perfect tense sentence, the participle usually comes later in the clause.
