Okay, so imagine you have a book with lots of pictures of different things from all over the world. But this book isn't about things like animals or buildings, it's about how people talk in different places.
People all around the world speak different languages, but did you know that the way they speak also differs in other ways? For example, some people might say the verb (the doing word) first in their sentence, while others might say the noun (the thing that's being talked about) first. Some people might have a lot of different sounds they use when they talk, while others might not have as many.
The World Atlas of Language Structures is like this book of pictures, but instead it shows you how people talk in different places. It has a map of the world, and you can click on different countries to see how the people speak there. For example, if you click on the United States, you can learn that most Americans say the verb first in their sentence, and that they have a lot of different sounds they use when they talk.
The World Atlas of Language Structures helps people learn about language differences all over the world. It's like a big treasure hunt for information about how people speak in different places!
