Okay kiddo, let's talk about something called "pseudoscientific language comparison". Pseudoscientific means it's not really science, but some people pretend it is. Language comparison is when we compare languages to see if they are similar or different.
Sometimes, people use pseudoscientific methods to compare languages. They might say that two languages are related just because they have a few similar words, but that's not enough evidence to prove it. They might also make up rules about how languages should be similar, instead of actually looking at the facts.
Just like how you should always do your homework and check your facts, real language comparison needs to be based on evidence and careful research. We have methods like the comparative method, which looks at the history of languages and how they change over time. This helps us to understand how languages are related to each other.
So, always be careful when someone says they are comparing languages, and make sure they are doing it based on real science!
