Italo-Celtic

Italo-Celtic is a family of languages that groups together two language families – Italic and Celtic.

Let's imagine a group of friends who all speak different languages, but some of them have some similarities in their languages. For example, they might all say "hello" or "goodbye" in a similar way. Similarly, there are some languages that have similarities in the way they sound or the words they use, and those languages can be grouped into a family.

Italian, Spanish, French and Portuguese are all examples of Romantic languages, which belong to the Italic family. These languages have similarities in the way they are spoken and written. Similarly, Irish, Welsh, and Scottish Gaelic are all part of the Celtic family of languages.

Now, Italo-Celtic is the idea that the Italic family and the Celtic family might have a common ancestor language or share some similarities. Think of Italo-Celtic as the family of the Italic and Celtic language families.

But Italo-Celtic is a controversial idea, and many experts disagree on whether it is a real language family. So, while it's an interesting concept, it's not something that every linguist agrees on.
