Core glossary

Okay, imagine you have a big book with all the words you could ever think of. Now, inside that book, you have a special section called the "core glossary." This section includes the most important words you need to know if you want to understand something really, really well.

Let's say you're learning about something new, like space or computers. You might not know all the special words that go with those things. So, the core glossary helps you out by giving you definitions of those words.

It's like having a special helper who knows everything about that topic and can explain it to you in a way that makes sense.

So, if you want to be an expert on something, it's a good idea to check out the core glossary so you can learn all the important words and what they mean.
