X

êX (uppercase: X, lowercase: x) is the seventeenth letter in Orish. Its sound is /x/ or /χ/, unvoiced velar or uvular fricative.

Pronunciation
To pronounce the sound of the letter X, raise the back of your tongue (dorsum) to your soft palate (velum) 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.

It's also recommended to push your uvula forward and lay it between the dorsum and the velum in increase friction.
