Here's a breakdown:
* "Vullis" means "garbage" or "trash".
* "Hoop" means "heap" or "pile".
So, "vullishoop" literally translates to "garbage heap". This is the most commonly used term for landfill in Afrikaans.
However, you might also hear "stortterrein", which means "dumping ground". This is a more general term for a place where waste is dumped, and it doesn't necessarily imply a specific method of disposal like a landfill.
