For a starter, I speak, read and write isiZulu fluently. I have been a top performer and slaying in Zulu language from primary school to secondary school while simultaneously learning other languages. I can translate from English to Zulu (or vice versa) and from Sotho to Zulu (or vice versa).
What is remarkable is that, I have never been to KZN, but people from that province are usually getting the impression that I am from the province, because of the way I speak and write the language.
Actions speak louder than words, so they say. But I say, put me to the test and see if I will yield perfect output.
