Ǫ

Not to be confused with ჹ or Q.

O with an ogonek (majuscule: Ǫ, minuscule: ǫ) is a letter of the Latin alphabet formed by the addition of the ogonek (from Polish: little tail) to the letter O. It is used in Western Apache, Mescalero-Chiricahua, Muscogee, Dadibi, Gwichʼin, Erie, and Navajo.^[1] It is also used in the Latin transcription of Old Church Slavonic, and the Proto-Slavic language, as well as in the Slavistic Phonetic Alphabet.^[2] It is also still in use for the writing of Old Norse, and used to be used sporadically in Polish.^[3]

Usage

The letter is used in the autochthonic languages of North America: Western Apache, Mescalero-Chiricahua, Muscogee, Dadibi, Gwichʼin, Erie, and Navajo.^[1] In such languages, it represents either a nasalized close-mid back rounded vowel ([õ]), or a nasalized ([ɔ̃]).

It is also used in the Latin transcription of Old Church Slavonic where it represents the nasal back vowel, as well as in the Proto-Slavic language where it represents a labialized non-front vowel. It is also used in the Slavistic Phonetic Alphabet, where it represents the nasalized O-sound, for example, the pronunciation of Ą in Polish.^[2]

It was used in Old Norse, where it represented the open back rounded vowel ([ɒ]) sound. Additionally, the letter sporadically used to be an alternative to Ą in Polish.^[3]

In academic transcription of Vulgar Latin, Ǫ represents the open-mid vowel /ɔ/ (contrasted with the close-mid vowel /o/, represented with an underdot (Ọ)).
