Khwizi, meaning "sheep"

And so even the Illui had a nickname. A close look at the “stone face” picture under the post “Nkami” below, reveals its resemblance to a sheep. Consequently some gave the Illui the nickname “sheep”. The word for “sheep” in Ikalanga is “khwizi” or “Pkhizi”, depending on the dialect.

The task of providing the Illui with milk at Nkami (Khami ruins) was carried out by several workgroups:
To tie together an animal’s hind legs as security while milking it is called “ku kaya” in Ikalanga. The workgroup responsible for this at Nkami was called “Bakaya”. Their totem is an elephant, therefore they do not eat or come into contact with an elephant – presumably for their own security;-)

We have noted that some Kalangas referred to (king) Anu as (king) Atho and that the word for “people” consequently varies from “Ba-Anu” to “Ba-Atho”. The Kalanga word for “to drink” is “ku ngwa”. The group that milked the animals for the Illui at Nkami are the Bangwa-Atho (Bangwato), meaning “those who enable the Illui to suckle”. The same group was referred to as Bangwa-khwizi (Bangwaketse) by the detractors of the Illui who nicknamed the latter - sheep.

According to some accounts, the Bangwato split from the Bakwena following a dispute over a lost cow!  This goes on to show how an extremely ancient dispute can be carried along generations until its logic and rationality completely escape the people concerned.
