Here die means the.
Afrikaans uses die as the definite article for nouns, and it does not change for gender the way articles do in some other languages. That makes it much simpler than languages like German.
So:
Because this is a simple main clause with the subject first, and Afrikaans often looks very similar to English in that pattern:
So the sentence follows a basic subject–verb–object order.
A useful extra point: Afrikaans is often described as a verb-second language. That means the finite verb normally comes second in a main clause. When the subject comes first, the result looks just like English:
But if another element comes first, the verb still stays second:
It can often cover both, depending on context.
Afrikaans commonly uses the simple present where English might use either:
If you want to strongly emphasize an ongoing action, Afrikaans can use a different structure, but in everyday language the simple present is very common.
So Ons kruis die straat could be understood as:
Context tells you which one is meant.
It is understandable and grammatical, but many speakers would more naturally say steek die straat oor for physically crossing a road or street.
So:
This is a good example of the difference between what is grammatically possible and what is most natural in everyday speech.
A rough English-friendly guide is:
ons kr-uis dee straht
A few notes:
If you want a very rough approximation, you could think:
ons kruys dee straat
But remember that the ui in kruis is a specifically Afrikaans/Dutch-type vowel sound, so no English spelling captures it perfectly.
