 The song "Siyahamba" is a South African hymn originally written in the Zulu language that became popular in North American churches in the 1990s.Standard Zulu as it is taught in schools, also called "deep Zulu" ("isiZulu esijulile"), differs in various respects from the language spoken by people living in cities (urban Zulu, "isiZulu sasedolobheni").Standard Zulu tends to be purist, using derivations from Zulu words for new concepts, whereas speakers of urban Zulu use loan words abundantly, mainly from English.
