O with diaeresis is used in the alphabets of the Altai, Khanty, Khakas, Komi, Kurdish, Mari, Shor and Udmurt languages.

Usage

In Altai, Khakas, Khanty and Shor, it represents the close-mid front rounded vowel /ø/.

In Komi, it represents the schwa /ə/, like the ⟨a⟩ in "allow".

In Kurdish, it represents the near-close near-back rounded vowel /ʊ/, like the ⟨oo⟩ in "book".

In Mari, it represents the open-mid front rounded vowel /œ/, similar to /ø/.

In Udmurt, it represents the open-mid back unrounded vowel /ʌ/, like the ⟨u⟩ in "up".

In Russian books until the beginning of the 20th century, the letter Ӧ has been sporadically used instead of Ё in foreign names and loanwords (for example, the city of Cologne, Germany, which is Köln in German, might have been rendered in Russian as "Кӧльн").

In Tatar, this letter appeared in the 1861 Cyrillic orthography by Nikolay Ilminsky. This letter was replaced by Ө in 1939.

O with diaeresis and macron (Ӧ̄ ӧ̄; italics: Ӧ̄ ӧ̄) is a letter from the Cyrillic script. It is used in the southern dialects of the Selkup language, to indicate a long Ӧ.
