Definition & Meaning of "zak"in English

What does "zak" mean in South African slang?

In South African slang, "zak" means money, usually cash, and is used in informal speech when talking about having, needing, or spending money. It is common in everyday South African English, especially in casual and working-class contexts. The term comes from Afrikaans "sak," meaning "bag" or "pouch," which shifted in slang usage to refer to money carried in a pocket or bag, and eventually came to mean money itself in general informal usage.
