RP

ʃ

Esh

Voiceless palato-alveolar fricative.

It is a fortis or strong consonant. The soft palate is in its raised position and the vocal folds do not vibrate. The front of the tongue touches the hard palate; the rims of the tongue are in contact with the upper teeth, and the tip and blade of the tongue with the alveolar ridge. The pulmonic air stream escapes with friction.
