Why is the Kalahari desert named Kalahari?

The name "Kalahari" is thought to originate from the Tswana language, possibly from the word "Kgalagadi", which refers to the Kgalagadi people who inhabit the region. Another possible origin is the Setswana word "Kgalagadi", which means "great thirst", referring to the dry conditions of the desert.
