Ƹ

Ƹ (minuscule: ƹ) is a letter of the Latin alphabet. It was used in the International Phonetic Alphabet for voiced pharyngeal fricative, but now the phonetic symbol officially used is [ʕ].

Although it looks like a reversed ezh (ʒ) or yogh (ȝ), it is based on the Arabic letter ʿayn (ع). (Unicode, however, refers to it expressly as "reversed ezh.")
