Well hello there little buddy! Today we're going to talk about something called "southernization." Do you know what it means to be in the south? That's right, it's when we talk about the lower part of a place, like a country or a state.
Now, "southernization" is a word that some people use to talk about how different parts of the world started to become more like the southern part of India. That means they started doing things the same way that people in the south of India did them.
Some of the things that were part of southernization include using spices and herbs in cooking, wearing cotton clothing, and even using certain kinds of math and science formulas.
Overall, "southernization" is just a fancy way of saying that different parts of the world became more similar to the southern part of India in some ways. It's pretty interesting to see how different cultures can influence each other over time!
