Voiced alveolar non-sibilant fricative

Okay kiddo, this is a tough word, but I'll explain it simply for you. Imagine you're playing with your toy cars and you want to make the sound of the car engine. You know how you do that by blowing air out of your mouth and making a sound like "vroom vroom"? Well, when we say the word "this" or "that", our tongue also blows air out of our mouth, but instead of a "v" sound, we make a different sound called a "th" sound.

Now, when we say the "th" sound, our tongue has to touch the top of our mouth, right behind our top teeth. That spot is called the "alveolar" because it's where some of our teeth come out. "Non-sibilant" means that our tongue doesn't make a hissing or whistling sound like a snake.

The last part, "voiced", means that when we make the sound, we use our voice to vibrate our vocal cords. So, when we say the word "this" or "that", our tongue touches the top of our mouth and we blow air out while making a "th" sound, and at the same time, we use our voice to make the sound come out smoothly.

That's what a "voiced alveolar non-sibilant fricative" is - it's a fancy way of saying the sound we make when we say words like "this" or "that".
