Questions & Answers about Die toeskouer sit langs my.
Yes. Die is the Afrikaans definite article, so here it means the.
A useful thing to know is that Afrikaans does not change the definite article for gender or case. So unlike languages such as German, you do not have to learn different forms like the for masculine, feminine, or neuter nouns. Die works very broadly.
So die toeskouer = the spectator / the viewer.
