Postalveolar consonant

Postalveolar consonants (sometimes spelled post-alveolar) are consonants articulated with the tongue near or touching the back of the alveolar ridge, farther back in the mouth than the alveolar consonants, which are at the ridge itself but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants [ʃ] [tʃ] [ʒ] [dʒ], as in the words "ship", "'chill", "vision", and "jump", respectively.
