Okay kiddo, let me try to explain to you the differences between Esperanto and Interlingua.
Esperanto and Interlingua are both languages that were created to make it easier for people who don't speak the same language to communicate with each other. They are called "constructed languages" because they weren't developed naturally like most languages are.
Esperanto was created in the late 1800s by a man named L.L. Zamenhof. He wanted to create a language that was easy to learn and that people from all over the world could use to communicate with each other. Esperanto has a really simple grammar and vocabulary, and it's designed to be easy to pronounce. The idea is that once you've learned Esperanto, you'll be able to communicate with people from other countries who also speak Esperanto, no matter what their native language is.
Interlingua, on the other hand, was created in the mid-1900s by a group of linguists. They based Interlingua on the grammar and vocabulary of Latin and other Romance languages, like Spanish, French, and Italian. The idea behind Interlingua is that if you know any of those languages, you'll already be able to understand a lot of Interlingua without having to learn a new language from scratch.
So, the main difference between Esperanto and Interlingua is that Esperanto is specifically designed to be easy to learn from scratch, while Interlingua is designed to be familiar to people who already speak Romance languages. Both languages are used by people all over the world, and they both have their strengths and weaknesses. But at the end of the day, they exist to bring people together, no matter where they come from or what their native language is.
