What is о?

о is a letter in the Cyrillic alphabet. It is derived from the Greek letter Omicron (Ο, ο) and represents the sound /o/.

• Sound Value: Typically, о represents the open-mid back rounded vowel ([ɔ]) or the close-mid back rounded vowel ([o]). Its specific pronunciation can vary depending on the language and the surrounding letters.
• Appearance: In both uppercase (О) and lowercase (о), it closely resembles the Latin letter O. This can sometimes cause confusion.
• Usage: It is a common letter in many Slavic languages that use the Cyrillic script, including Russian, Ukrainian, Belarusian, Bulgarian, Serbian, and Macedonian.
• Variations: Diacritics can be added to о to indicate different pronunciations in specific contexts. For example, in Bulgarian, an acute accent (ó) indicates stress.
