U+03DA "Ϛ" Greek Letter Stigma is a historical ligature in the Greek alphabet, originally formed from the combination of sigma and tau, often used in medieval manuscripts to represent the sound /st/. It should not be confused with the similar-looking digamma or final sigma, as stigma has its own distinct uppercase form (U+03D9 "ϛ") and primarily appears in archaic or liturgical contexts, such as in Greek numerals where it stands for the number 6. While now largely obsolete in modern Greek writing, it persists in certain typographic and scholarly settings.
