S

êS (uppercase: S, lowercase: s) is the thirteenth letter in Orish. Its sound is /s/, unvoiced alveolar fricative.

Pronunciation
To pronounce the sound of the letter S, raise the tip of your tongue to your alveolar ridge and block the air just a little bit so that when you release air through it it will create a friction sound. Not less important, keep your vocal chords loose and don't vibrate them.

Some people have lisp, and they may pronounce this sound as an interdental sound, with the front part of their tongue placed under their top teeth. In Orish this is not a mistake to pronounce this sound like that.
