firstly,we had family names, your colonial education is garbage as you,that we had S'gidi kaSenzangakhona, that how we recorded our lineage , you might need tpo relaxx witrh woke BS, secondly, African language does not have what? Mchunu as name and iChunu as bhinca person (1800s)
There's no such garbage in any African language, it's colonial rubbish.
Africans do not have a linear history at anytime , "woke" is garbage you may use with your cramming buddies.
You cannot explain what is "Nguni" and simply impute Mnguni using English, you don't know what you are talking about and just crammed it.
Africans did not have surnames until 1920s as a start
