I'm from South America and I've been fluent (at least in my opinion) in English for several years as of now. With this in mind it has really called my attention lately that I've heard Afro-American people say, for example,
"I don't like no cats" instead of "I don't like cats". With double negation.
And the other one is, for example,
"Look at them kids" instead of "Look at the kids". With them instead of the.
It is not really confusing tbh but I'm just curious about why this happens?
