The /s/ Sound, Voiceless Alveolar Fricative

/s/

/s/ is a voiceless alveolar fricative. To make it, the tip or blade of the tongue touches the alveolar ridge, just behind the upper teeth and the air is pushed through a narrow gap, which makes friction. It is voiceless, so the vocal folds do not vibrate.
