Okay, so gobbledygook is when people say or write things that are really hard to understand. It's like they're speaking a different language that doesn't make sense to you. It's like when your mom or dad tells you to do something, but they use big, confusing words that you don't understand. It can happen to grown-ups too! Sometimes people use gobbledygook when they want to sound fancy or important, but really it just makes things more confusing. So, it's important to try and explain things in a way that everyone can understand, just like how I'm explaining gobbledygook to you right now.
