Die beligting kom van die sonlig.

Because die is the Afrikaans definite article, meaning the. It does not change for gender the way articles do in some other languages.

So here:

• die beligting = the lighting
• die sonlig = the sunlight

Afrikaans uses die for:

• singular nouns
• plural nouns
• all grammatical genders

So it is normal to see die more than once in one sentence.

Beligting means lighting or illumination. It often refers to the lighting as a condition, effect, or system.

Lig usually means light more directly.

For example:

• lig = light
• beligting = lighting

So Die beligting kom van die sonlig focuses on the lighting/illumination coming from sunlight.

In some everyday contexts, a speaker might also simply say Die lig kom van die son if they mean The light comes from the sun.

Kom van means comes from.

It is a very common Afrikaans way to show origin or source.

So:

• Die beligting kom van die sonlig = The lighting comes from the sunlight

You can think of it as describing where something originates.

Other examples:

• Hy kom van Kaapstad. = He comes from Cape Town.
• Die geld kom van my broer af. = The money comes from my brother.

Because van is the normal word for from when you are talking about a source or origin.

• van = from
• uit = out of / from inside

Since sunlight is the source of the lighting, van is the natural choice.

Compare:

• Die lig kom van die son. = The light comes from the sun.
• Hy haal die boek uit die sak. = He takes the book out of the bag.

You use uit when something comes from inside something else.

Afrikaans verbs are much simpler than English verbs in the present tense. In most cases, the verb does not change for person or number.

So you get:

• ek kom = I come
• jy kom = you come
• hy kom = he comes
• ons kom = we come
• hulle kom = they come

Unlike English, Afrikaans does not add -s for he/she/it in the present tense.

That is why kom stays kom.

Because Afrikaans main clauses normally follow the verb-second rule.

That means the finite verb usually appears in the second position in the sentence.

Here the order is:

• Die beligting = subject
• kom = finite verb
• van die sonlig = rest of the sentence

So the structure is very normal Afrikaans word order.

If you move another element to the front, the verb still stays second:

• Vandag kom die beligting van die sonlig.

That is an important Afrikaans pattern to get used to.

Because Afrikaans usually writes compound nouns as one word.

So:

• son
  • lig = sonlig

This is very common in Afrikaans. English often uses separate words where Afrikaans prefers a compound.

More examples:

• huis
  • deur = huisdeur
• skool
  • bus = skoolbus

So sonlig is exactly what you would expect in Afrikaans spelling.

Both are possible, but the meaning changes slightly.

• van sonlig = from sunlight in a general sense
• van die sonlig = from the sunlight, meaning a more specific or definite sunlight

In many contexts, van sonlig may sound more general and natural if you are talking about sunlight as a substance or general source.

So:

• Die beligting kom van sonlig = the lighting comes from sunlight
• Die beligting kom van die sonlig = the lighting comes from the sunlight

The version with die is more definite.

The sentence is understandable and grammatical, but whether it sounds fully natural depends on the context.

A native speaker might sometimes choose a simpler or more idiomatic version, such as:

• Die lig kom van die son.
• Die vertrek word deur sonlig verlig.
• Die kamer kry sy lig van die son.

Your original sentence is fine if you specifically want to talk about the lighting coming from sunlight, but in everyday speech Afrikaans often prefers a more direct wording.

Yes, but it is a little more formal or specific than lig.

You often see beligting in contexts like:

• room lighting
• stage lighting
• street lighting
• photography
• design

So it is a useful word, but in casual everyday conversation people may often use lig if they just mean light in a general way.
