What “sigma” means
Wiktionary · Wikipediasigma/ˈsɪɡmə/
- nounThe eighteenth letter of the Classical and Modern Greek alphabets, the twentieth letter of Old and Ancient.
Sigma is the eighteenth letter of the Greek alphabet. When it is used at the end of a letter-case word, the final form (ς) is used. In Ὀδυσσεύς (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end.
