The open-mid central rounded vowel, or low-mid central rounded vowel,[1] is a vowel sound, used in some spokenlanguages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɞ⟩, and the equivalent X-SAMPA symbol is 3\. The symbol is called closed reversed epsilon. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ɔ̈⟩.
IPA charts were first published with this vowel transcribed as a closed epsilon, ⟨ʚ⟩ (that is, a closed variant of ⟨ɛ⟩, much as the high-mid vowel letter ⟨ɵ⟩ is a closed variant of ⟨e⟩), and this variant made its way into Unicode as U+029AʚLATIN SMALL LETTER CLOSED OPEN E. The IPA charts were later changed to the current closed reversed epsilon ⟨ɞ⟩, and this was adopted into Unicode as U+025EɞLATIN SMALL LETTER CLOSED REVERSED OPEN E.
