• чэфы́ "happy",
• чэты́ "chicken".

Чъ чъ чъы – Has no equivalent in English. This is a  forelingual, hard, voiceless, aspirate affricate.  When the closed vocal organs are being torn by the passing airflow, a sharp, short, snapping sound comes out:

• чъыга́й "oak",
• чъы1э́ "cold".

Ч1 ч1 ч1ы – Has no equivalent in English. This is a forelingual, abruptive, sibilant afficate. To pronounce the sound, the vocal cords merge together at the beginning and then open at the end producing a noise. This sound is more tense than voiced and voiceless sibilant affricates:

• ч1ып1э́ "place",
• ч1ыфэ́ "debt".
