Voiceless apicoalveolar fricative

Okay kiddo, this is a sound that some people make in their language. It's made by putting the tip of your tongue (the little pointy thing in your mouth) on the bumpy part behind your front teeth (where you bite your food) and pushing air out of your mouth while making a hissing sound. The sound you make is like a soft "s" or "sh" sound, but it's made by putting your tongue in a specific spot in your mouth. Imagine you're pretending to be a snake or a big wind blowing through your teeth, and that's kind of what it sounds like!
