A postalveolar sound is pronounced with the tongue positioned slightly behind the alveolar ridge. The alveolar ridge is the bony ridge located just behind the row of upper teeth. Together with alveolar consonants, they create a palatal class of consonants. For English speakers, the difference between Gaelic broad and slender consonants is most noticeable in the difference between alveolar [s] said to be broad and postalveolar [ʃ] said to be slender (or palatalized).
The postalveolar sounds of English [ʃ], [ʒ], [dʒ], [tʃ]; the postalveolar sounds of Gaelic [ʃ], [tʲ], [dʲ].
