Questions & Answers about Niemand kan weet hoekom die bottel reeds leeg is nie.
Because Afrikaans normally uses negative concord: a negative idea is often marked twice.
In this sentence:
- niemand = nobody / no one
- final nie closes the negative statement
So Afrikaans says, in effect, Nobody can know ... not.
That may feel redundant to an English speaker, but it is normal Afrikaans grammar.
Compare:
- Niemand verstaan dit nie. = Nobody understands it.
- Niks help nie. = Nothing helps.
With words like niemand, niks, and geen, you usually still get the final nie.
Because that nie belongs to the main clause, and in Afrikaans the second negative marker usually comes near the end of the whole clause.
Here the structure is:
- Niemand kan weet = main clause
- hoekom die bottel reeds leeg is = embedded clause
- nie = closes the negative main clause
So Afrikaans keeps the whole idea together and then ends the negative with nie:
- Niemand kan weet hoekom die bottel reeds leeg is nie.
This is very common when a main clause contains a subordinate clause.
