Because die applies to the entire list of items that follow.
So:
means the drain pump, pump filter, door latch, rubber seal and detergent drawer.
This works much like English, where you can also say the drain pump, pump filter, door latch, rubber seal and detergent drawer without repeating the before every noun.
You could repeat die before each item, but it is usually unnecessary unless you want extra emphasis or clarity.
Because Afrikaans very often writes compound nouns as one word.
This is very common and very important in Afrikaans spelling.
For example:
English often writes similar expressions as two words, hyphenated words, or one word depending on the term. Afrikaans strongly prefers a single compound noun.
It is a compound noun:
So deurgrendel is the door latch or door lock mechanism.
The exact English translation can vary a little depending on the machine or technical context, but the basic idea is the part that secures the door.
It is another compound noun:
And wasmiddel itself can be broken down further:
So wasmiddellaai literally means detergent drawer.
Yes, very similar.
The structure is:
So the sentence follows a straightforward subject–verb–object pattern, just like English:
Afrikaans does not have grammatical gender in the way languages like German or Dutch do.
So nouns like dreineerpomp, pompfilter, deurgrendel, rubberseël, and wasmiddellaai do not take different articles based on masculine, feminine, or neuter gender.
That is one reason why die is so useful: it works broadly without gender changes.
A rough English-friendly guide would be:
Ons toets die dreineerpomp, pompfilter, deurgrendel, rubberseël en wasmiddellaai.
Approximate pronunciation:
ons toost dee DRAY-neer-pomp, pomp-fil-ter, duhr-GREN-del, RUY-ber-seel, en VUS-mid-del-lie
