AI overview

Omicron (Ο/ο) is the fifteenth letter of the Greek alphabet, derived from the Phoenician letter ayin, and it represents a back rounded vowel sound. The letter is important historically because it gave rise to the letter O in both the Roman and Cyrillic alphabets, making it a foundational character in multiple writing systems.
