Help please with Language

I'm a student foreign language faculty. Study English Language.
I've got the task in my diploma: "To write and analyze linguistics concepts in South African English". Exactly, the concepts - Own, my, native VS Alien, strange, other, foreign. I don't want to offense You. I just want to learn more about South African Language.
How these meanings can be represented in language: proverbs, idioms, phrases, quotations etc. in books, songs, speeches, poems. Anything that can help.
I need any words and their representations with these meanings. With the meaning of differences between African People and White people.
I don't want to insult you. I am just a linguist.
I ask you for help, please. Because I'm at a loss
