InTurkic languages, it commonly represents the front rounded vowels /ø/ or /œ/. In Kazakh and Karakalpak, it may also express /wʉ/. InMongolic languages, it usually represents /o/ or /ɵ/. The letter has also been adopted in the spelling of theKomi-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 adouble vowel.[1][2][3]
Until a new alphabet was published in 2016, Oe was used to represent /ø/ inNegidal.
Oe is most commonlyromanized as⟨Ö⟩; but itsISO 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⟩.
