Okay kiddo, so "delph-in" is like a really cool computer program that helps us talk to computers in different languages. You know how you can speak English, and your friend might speak Spanish or Chinese? Well, computers talk in their own language too, and it can be hard for us humans to understand them.
But with delph-in, scientists can make the computer understand English or other languages! It's kind of like magic, but it works by breaking down sentences into smaller parts and then figuring out the meanings of those parts.
So let's say you wanted to tell the computer to "open the door". Delph-in would break down that sentence into two parts: "open" and "the door". Then it would figure out that "open" means to unlock or move something, and "the door" means the thing you want to unlock or move.
And just like that, the computer knows exactly what you want it to do! It's like having your very own language translator in your pocket. Cool, huh?
