Meaning and origin of Omega
Omega is a Greek name that means “last letter of the Greek alphabet”.
Omega is the last letter of the Greek alphabet, written as a large or long o. Its name means great o, from the Greek o mega. In the Book of Revelation, God says, I am the Alpha and the Omega, the beginning and the end, which gives the letter a religious meaning of completion. It is said oh-MAY-guh in American English. As a given name it is rare and used for both boys and girls. Some families choose it for a last child, drawing on its meaning of the end. The Swiss watch brand Omega is a familiar association.
