Because Afrikaans verbs usually do not conjugate the way English verbs do.
With a regular verb like stap, the form stays the same:
So unlike English, you do not get forms like walk / walks. The verb usually stays unchanged.
That is a very normal Afrikaans word order.

Afrikaans often places time expressions like vandag after the verb in a main clause.
This order sounds natural and neutral:
You can sometimes move elements around for emphasis, but this version is a standard one.
Yes, it can, depending on context.
Afrikaans often uses the present tense for actions happening now or planned actions in the near future. Because vandag is included, the sentence could mean something like:
The exact nuance depends on the situation.
A rough English-friendly pronunciation would be:
ons stahp fun-DAKH tuh-RUK
A few helpful notes:
Pronunciation varies a bit by speaker and region, but that is a useful starting point.
Ons stap nie vandag terug nie.
Afrikaans typically uses double nie in standard negation:
So the pattern here is:
This is one of the most important sentence patterns in Afrikaans.
Yes, in many contexts you could.
Loop often also means walk, and in everyday Afrikaans it is very common.
A rough difference is:

In this sentence, it is best understood as a separate word meaning back.
So stap is the main verb, and terug adds the idea of direction.
Afrikaans does have combinations where a directional word and a verb are closely linked, but for a learner, the easiest way to read this sentence is:
That analysis will serve you well here.
