Because Afrikaans usually writes compound nouns as a single word.
So:
English often writes these as two words, but Afrikaans commonly joins them together. This is very normal in Afrikaans.
Other examples of this pattern are things like:
Bankstaat means bank statement.
It refers to the statement from your bank showing things like:
So in this sentence, it is not talking about a bank as a bench, and it is not talking about a state as a country. The compound as a whole has the specific meaning bank statement.
Mostly yes. Is is the present-tense form of to be.
So:
One useful difference from English is that Afrikaans uses is with all persons in the present tense:
So Afrikaans does not switch between am / is / are the way English does.
Here it works like a predicate adjective/complement after is.
In other words, it describes the subject:
English does something very similar in The bank statement is online.
So for a learner, the easiest way to understand it is: after is, aanlyn describes the subject.
Afrikaans normally uses double negation.
So the negative version is:
Die bankstaat is nie aanlyn nie.
Notice the two nie words:
This double-negation pattern is one of the most important features of standard Afrikaans.
A rough English-friendly pronunciation is:
dee bunk-staht is AHN-layn
That is only an approximation, but it can help you get started.
A few pronunciation notes:
So the full sentence is said smoothly as:
Die bankstaat is aanlyn.
