Oe or barred O (Ө ө; italics: Ө ө) is a letter of the Cyrillic script.

Shape

Its form was copied from the Latin letter barred O (Ɵ ɵ) used in Jaꞑalif and other alphabets.^{[citation needed]}

Despite having a similar shape, it is related neither to the Greek letter theta (Θ θ/ϑ) nor to the archaic Cyrillic letter fita (Ѳ ѳ).

Usage

Oe is used in the alphabets of the Bashkir, Buryat, Kalmyk, Karakalpak, Kazakh, Komi-Yazva, Kyrgyz, Mongolian, Sakha, Selkup, Tatar and Tuvan languages.

In Turkic languages, it commonly represents the front rounded vowels /ø/ or /œ/. In Kazakh and Karakalpak, it may also express /wʉ/. In Mongolic languages, it usually represents /o/ or /ɵ/. The letter has also been adopted in the spelling of the Komi-Yazva language, where it represents a close-mid centralized back unrounded or weakly rounded vowel /ɤ̹̈/. In Kyrgyz, Mongolian and Tuvan, the Cyrillic letter can be written as a double vowel.^[1]^[2]^[3]

Until a new alphabet was published in 2016, Oe was used to represent /ø/ in Negidal.

Oe is most commonly romanized as ⟨Ö⟩; but its ISO 9 transliteration is ⟨ô⟩. In 2018, there were proposals to use ⟨Ó⟩ as a romanization of Oe in Kazakh, but a year later it was certified as ⟨Ö⟩.

The International Phonetic Alphabet uses the identically shaped Latin counterpart, ɵ, to represent the close-mid central rounded vowel, and sometimes also the mid central rounded vowel.
