My dear friends,
The word "jabulani" means "celebrate" or "rejoice" in Zulu.
Zulu is the language of the Zulu people, with about 10 million speakers, the vast majority (over 95%) of whom live in South Africa. Zulu is the most widely spoken home language in South Africa (24% of the population). It is also understood by more than half of the population. It became one of South Africa's 11 official languages in 1994.
I am glad I have this name - it shows the world really comes together when doing sports, as people celebrate football passionately all the time!
