Hello there! Do you know what languages are? They are different ways for people to communicate with each other. But when people who speak different languages want to talk to each other, it can be really hard! Sometimes they use a thing called an "interlingua" to help them.
An interlingua is like a special language that people can use to understand each other when they speak different languages. It's not a new language, but it's kind of like a mix of different languages. It takes words and grammar rules from lots of different languages and puts them together in a way that makes sense for everyone.
For example, if someone speaks Spanish and someone else speaks English, they might use an interlingua called "Esperanto" to talk to each other. The words and grammar rules in Esperanto are taken from lots of different European languages, so it's easy for lots of people to learn and understand.
Interlinguas are really helpful because they make it easier for people from different countries to talk to each other. They can be used in lots of different situations, like when people are traveling, or when they're talking to someone online who speaks a different language.
In summary, an interlingua is like a special language that people use to talk to each other when they speak different languages. It's a mix of words and grammar rules from lots of different languages, and it helps people communicate with each other.
