Inkozi (pronounced "ing-caw-zee") is the Xhosa word for danger and in this case is found on a sign posted at the location of an electricity substation in the Wooltru building (mentioned in my previous post).
Even though it's commonly spoken in our Western and Eastern Cape provinces, when considered in a global context, Xhosa is a relatively small language. What I was happy to find out is that there's a Xhosa edition of Wikipedia available! While it is a relatively small edition, with only 115 articles at the time of writing this post, it was once explained to me that it's a major step towards documenting what the Xhosa elders have through the centuries passed on to their children by word of mouth only.
I found this interesting and alternative usage of an abbreviated form of the word, and although I doubt it's legitimacy I found the dialogue at the bottom of the text terribly entertaining. :)
