Affricates start as a complete closure in the vocal tract (like a stop).
They then release into a fricative, where there is a partial closure causing turbulence in the airflow.
They are considered to be a single sound, even though they involve two different manners of articulation (stop and fricative).
Articulation of Affricates:
/tʃ/ (as in "chat"): The tongue makes a complete closure at the alveolar ridge, then releases into a fricative by creating a narrow constriction with the tongue and the roof of the mouth.
/dʒ/ (as in "judge"): The tongue makes a complete closure at the alveolar ridge, then releases into a fricative by creating a narrow constriction with the tongue and the roof of the mouth.
Examples of Affricates in English:
"ch" as in "chat"
"j" as in "judge"
