Okay kiddo, so you know how we have different names for different towns and cities, right? Well, sometimes these towns are in different countries, and they speak different languages, so they have different names!
Imagine you're standing right on the border between two countries, and you're looking at two towns on either side of the border. Let's say one town is called "Smithville" in English and the other town is called "Villasmith" in Spanish.
Now, that's all well and good if you're only talking to people who speak one language, but what if you're talking to someone who speaks the other language? They might not know what town you're talking about!
So what do we do? Sometimes, towns will have a different name in different languages to make sure everyone knows what we're talking about. So in this case, the English-speaking people might call the town "Smithville" and the Spanish-speaking people might call it "Villasmith."
This can get kind of tricky sometimes, especially if the names are very different or if there are a lot of languages involved. But usually, people are pretty good at figuring out what name to use depending on who they're talking to.
