Oʻ (o with turned comma above right; minuscule: oʻ) is the 25th letter of the Uzbek Latin alphabet, representing the close-mid back rounded vowel pronounced as /link/. It was adopted in the revision of the alphabet, replacing Ö.[1] It was also used in the Karakalpak alphabet until 2016, when it was replaced with Ó. In the Uzbek Cyrillic alphabet, it corresponds to Ў.
In Unicode, Oʻ is not encoded as a precomposed character, but rather as a sequence of or and . Since the modifier letter isn't readily typeable on the Uzbek Latin keyboard layouts shipped with Microsoft Windows as of 2022, the substitution of other characters such as and is very common.[2]
