Sabela

Sabela is a covert communication dialect of several major South African languages formed by the Numbers gang. Sabela was originally developed in the mines during the early 1900's as a means of communication between the members of The Numbers Gang but as the gang's influence in grew in various South African prisons, the language became eminent in prison and since then, released inmates have introduced it to the general populace of South Africa. UkuSabela means to respond in various Nguni languages.

Structure
Sabela inherits most of its vocabulary, phonology, and syntax from Xhosa and Zulu. Due to the Xhosa and Zulu influence, Sabela contains click consonants.

Die Antwoord
Sabela is often used by groups associated with the Zef movement, such as Die Antwoord. The group's 2019 gqom single "Baita Jou Sabela" (featuring Slagysta) contains lyrics partially written in Sabela that talk about the South African prison system. The song's music video showcases the corruption present in the South African prison system.
