Open o or turned c (majuscule: Ɔ, minuscule: ɔ) is a letter of the extended Latin alphabet. In the International Phonetic Alphabet, it represents the open-mid back rounded vowel. It is used in the orthographies of many African languages using the African reference alphabet.
The Yucatec Maya language used Ɔ to transcribe the alveolar ejective affricate [t͡sʼ] consonant in the orthography of the Colonial period. Now dz or tsʼ is preferred.[1]
