A consonant sound in which the air flow is initially stopped, but then released slowly with friction, as in /tʃ/ is called what?

Explanation:
Affricates combine a momentary complete stop of airflow with a gradual release through a narrow constriction that creates friction. In /tʃ/, the tongue first blocks the air just like a stop, then releases into a constricted passage that produces a frictional noise as the air escapes. That stop-plus-friction sequence in one gesture is what defines an affricate. Fricatives have friction without an initial stop, plosives have a stop with a rapid release and no sustained friction, and nasals route air through the nasal cavity with no friction noise. So /tʃ/ is classified as an affricate.
