Xi Greek Letter Meaning Meaning & Symbolism

Ξ ξ — Xi — represents the number 60; a distinctive triple-barred letter. As part of the alphabet that gave us the word 'alphabet' itself, its symbolic life now far exceeds its role in Greek spelling.

Origin & History

The Xi Greek Letter Meaning (Ξ) 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 — xi participated in that sacred arithmetic. Fraternities later adopted Ξ ξ for the values its sound and shape suggested.
