A linguistic homeland is like a family tree, but for a language instead of people. Just like how you have parents, grandparents, and great-grandparents who all came from the same place and might have similar traditions and customs, languages also have ancestors that are related to each other.
Let's say you speak English. English comes from a family of languages called the Indo-European languages. This means that English has ancestors like Latin, Greek, and Sanskrit. These languages are all related to each other, even though they might sound very different and be spoken in different parts of the world.
A linguistic homeland is the place where a language and its ancestors originated from. It's like the birthplace of the language family. Just like how you might have relatives who still live in the same town where your ancestors came from, there might be people who still speak languages that are related to the one you speak in the linguistic homeland.
Studying linguistic homelands can help us understand how languages have changed over time and how they are related to each other. It's kind of like investigating your family history to understand where you come from and why you do certain things in a certain way.
