ซิกมา

Also known as σ, ς, sigma

Sigma ( ; uppercase Σ, lowercase σ, lowercase in word-final position ς; ) is the eighteenth letter of the Greek alphabet. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In '''' (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.

AI overview

Sigma (Σ) is the eighteenth letter of the Greek alphabet with two lowercase forms: σ is used in the middle of words, while ς is used at the end of words. This distinction between middle and final forms is unique to sigma among Greek letters and appears in words like "Odysseus," where the two middle sigmas differ visually from the final sigma.
