Omicron Greek Letter Meaning Meaning & Symbolism

Omicron (Ο ο) is a letter of the Greek alphabet symbolizing "little o" — the number 70. Greek letters escaped pure language centuries ago and now work as symbols in their own right.

Origin & History

The Omicron Greek Letter Meaning (Ο) comes from The Greek alphabet, adapted from Phoenician c. 800 BCE. In the Greek mystical and numerological tradition (isopsephy), every letter was also a number, so words could be summed into meanings — omicron participated in that sacred arithmetic. Fraternities later adopted Ο ο for the values its sound and shape suggested.
