Sigma Greek Letter Meaning Meaning & Symbolism

Σ σ — Sigma — represents summation and standard deviation — also internet slang for an independent "lone wolf". 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 Sigma Greek Letter Meaning (Σ) 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 — sigma participated in that sacred arithmetic. Fraternities later adopted Σ σ for the values its sound and shape suggested.
