Die water dreineer deur die dreineringsgat.

Die is the Afrikaans definite article, meaning the. It is used before both water and dreineringsgat because both nouns are definite here:

• die water = the water
• die dreineringsgat = the drainage hole / the drain hole

A useful thing to remember is that Afrikaans uses die for all genders and for both singular and plural definite nouns. Unlike English, there is no separate masculine or feminine article.

No. In Afrikaans, present-tense verbs usually do not change according to the subject.

So you get:

• Ek dreineer
• Jy dreineer
• Die water dreineer
• Ons dreineer

The verb stays dreineer each time. This is much simpler than English, where you get I drain but it drains.

Deur usually means through. In this sentence, it shows the path the water takes:

• deur die dreineringsgat = through the drainage hole

So deur is the natural choice when something passes through an opening, space, or channel.

It is a compound noun, which is very common in Afrikaans.

It is built from:

• dreinering = drainage
• gat = hole

Together they form dreineringsgat, literally drainage-hole.

Afrikaans normally writes compounds as one word, even when English might write them as two words, such as drain hole or drainage hole.

Because Afrikaans strongly prefers compound nouns to be written as a single word.

So where English often has:

• drain hole
• water pipe
• kitchen door

Afrikaans often writes:

• dreineringsgat
• waterpyp
• kombuisdeur

This is a very important spelling habit to get used to in Afrikaans.

Yes. This sentence follows a very familiar main-clause pattern:

• Die water = subject
• dreineer = verb
• deur die dreineringsgat = prepositional phrase

So the structure is essentially:

Subject + Verb + Prepositional phrase

That is very close to English: The water drains through the drainage hole.

Die water refers to a specific water, not water in general.

For example:

• Die water dreineer deur die dreineringsgat. = the specific water is draining through the hole.
• Water is belangrik. = water is important in general.

So die water is used when the speaker means a particular amount or body of water, such as the water in a sink, tub, tray, or container.

It is a real Afrikaans word, although it is clearly related to English drain and international technical vocabulary.

Afrikaans often uses words like this, especially in practical, technical, medical, or mechanical contexts. So dreineer is perfectly understandable and normal.

Depending on context, speakers might also use other verbs such as:

• uitloop = run out
• wegvloei = flow away
• afvloei = drain off / flow off

But dreineer is absolutely fine here.

In this sentence, dreineer is being used intransitively. That means the subject is doing the draining itself:

• Die water dreineer = The water drains

But the verb can also be used in a more transitive sense in some contexts, where someone drains something:

• Hulle dreineer die dam. = They drain the dam.

So the sentence you have uses the simpler the water drains meaning.

A rough learner-friendly guide would be:

• Die ≈ dee
• water ≈ vaa-ter or vah-ter
• dreineer ≈ dray-neer
• deur ≈ something like dayr, but with a rounded vowel
• dreineringsgat ≈ dray-neh-rings-khat

A few pronunciation notes:

• Afrikaans w often sounds closer to English v
• the g in gat is not a hard English g as in go
• Afrikaans g is usually a guttural sound, like the ch in Scottish loch or German Bach

So gat is closer to khat / ghat than to English gat with a normal g.

It is grammatical and understandable, and it sounds especially suitable in a descriptive, technical, or instructional context.

In very everyday speech, someone might also say something like:

• Die water loop deur die afvoergat uit.
• Die water vloei deur die gat.

These alternatives may sound a bit more conversational depending on the situation. But Die water dreineer deur die dreineringsgat is still a good, correct Afrikaans sentence.

Both can refer to a drain-type hole, but the nuance is slightly different.

• dreineringsgat is closely tied to the idea of drainage
• afvoergat is tied to afvoer, meaning outflow, discharge, or drain-off

In many practical situations, they could be understood similarly. Afvoergat may sound a bit more everyday in some contexts, while dreineringsgat can sound a bit more technical or formal.
