Behemoth

A behemoth is a really big and powerful thing. Imagine a huge dinosaur or a giant monster from a movie. It's like that, but instead of being alive, it could be something like a big machine or a huge company that takes up a lot of space and has a lot of power. When people talk about behemoths, they're usually talking about something that's really impressive and maybe a little bit scary because of how big and strong it is.
