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.

Similar looking letters[edit]

The first of these Claudian letters is the antisigma.

Open o looks like a reversed letter 'C'. Claudius introduced a Ɔ (the antisigma) with the intention of replacing bs and ps.

Definition from Aasen (1873), Norsk ordbog med dansk forklaring, showing the Danish explanatory symbol “ɔ:”.

The Scandinavian explanatory symbol (forklaringstegnet) can be typeset using the open o followed by a colon, thus: ɔ:. It is used to mean "namely", "id est", "scilicet" or similar.[3]

This letter is often used to refer to the Copyleft official sign, which looks like an open o with a circle around it.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
