ELI5: Explain Like I'm 5

Cognate

A cognate is a fancy word that means two words in different languages that look and sound very similar. Imagine you have a friend who speaks a different language than you. Both of you spoke your languages to each other and you suddenly realized that some words sound alike and have the same meaning. Well, those words are called cognates! It's like you and your friend have some secret words that are the same in both of your languages. It can help you understand each other better and even learn new words in another language. Cool, huh?
