Afrikaans, like Dutch and German, very often writes compound nouns as a single word.
So:
This is completely normal. English often writes similar ideas as two words, but Afrikaans usually joins them.
Other examples:
Literally, hartklop is made up of:
So the literal idea is heartbeat. But in real usage, especially with devices like watches or fitness trackers, hartklop can also refer to pulse or heart rate, depending on context.
In this sentence, with sporthorlosie, it most naturally refers to the heart-rate reading shown by the watch.
Wys means show, display, or sometimes point out, depending on context.
In the present tense, Afrikaans verbs usually do not change form for different subjects. That means the same verb form is used with I, you, he, she, it, we, and they.
Examples:
So wys stays wys.
Yes, in this simple main clause it is:
So the pattern is subject + verb + object, just like basic English word order.
However, Afrikaans has an important verb-second tendency in main clauses. If another element comes first, the verb still stays in second position:
So this sentence looks very English-like, but Afrikaans word order becomes more noticeably different in other sentence types.
Usually shows.
Afrikaans often uses the simple present where English might use either:
So Die sporthorlosie wys die hartklop can describe a general fact or what the watch is displaying right now, depending on context.
If someone wants to be extra explicit about an ongoing action, Afrikaans can use a longer form, but in everyday language the simple present is very common and natural here.
A rough learner-friendly guide:
wys → roughly vays
The w in Afrikaans often sounds like an English v.
sporthorlosie → roughly sport-hor-LO-see
hartklop → roughly HART-klop
