omicron
Little O, Greek
Omicron is the fifteenth letter of the Greek alphabet (Ο, ο), corresponding to the short "o" sound.
In English, the word appears mainly in scientific contexts—naming stars (Omicron Persei), variants of viruses, or in fraternity and sorority names.
The COVID-19 variant designated Omicron in 2021 brought the term into widespread use: The Omicron wave hit just before the holidays.
