Thou

Thou is a really old word that some people used to use a long time ago to mean "you." It's like a fancy version of "you." Imagine if you were playing dress-up and you had a really fancy outfit on. "Thou" is like the fancy outfit version of "you."

It's not a word that people use very much anymore, but you might hear it in old movies or books. It can be confusing because we don't use it in everyday life anymore. But if you hear someone say it, just remember that it means "you" and they might be trying to sound fancy or old-fashioned.
