ʢ

ʢ is a symbol that looks like an upside-down question mark. It's called a "voiced pharyngeal implosive" which means it's a sound that you make in the back of your throat by closing your throat and pulling in air instead of pushing it out. Think of it like sucking in really hard with a straw. This sound is used in some languages, but not many people know how to make it or even recognize it. It's like a secret sound!
