How to make this sound:

Video Text:

The ch and jj consonant sounds.  These are affricate sounds, which means that they are made both by a stop, and by passing air through a constricted area.  The stop happens, ch, when the front part of the tongue raises and presses against the roof of the mouth, not allowing air to pass through.   The tongue is then pulled down, but the teeth remain together, or almost together, which is then the constricted space that the air passes through to make the sound.  These two sounds are paired together because they both take this mouth position.  The ch sound is unvoiced, which means you only release air through your mouth, whereas the jj sound is voiced, because you're actually making sound with your vocal cords.  Notice also that the lips take, ch, a very rounded and out position.  So the corners of the mouth come in, ch, and the top and bottom part of the lips really come away from the face, showing a lot of the teeth.  Ch, jj.
