Definition

Affricates occur when a complete closure is made

somewhere in the mouth, and the soft palate is raised. Air pressure increases behind the closure, and is then released more slowly than in plosives.

Characteristics

Palato-alveolar sounds. The tongue tip, blade and rims close against the alveolar ridge and side teeth. The front of the tongue is raised, and when the air is released, there is audible friction. The soft palate is also raised. /t / is unvoiced and fortis /strong. /d / is voiced and lenis/weak. /d / is devoiced at the end of a word
