San was a letter of the Greek alphabet, between Pi and Qoppa. It usually had a phonemic value of /s/, but eventually became disused in favour of sigma. The latest attested use is in the 6th century BC. It was also used in Arcado-Cypriot as [ts], replacing a previous labio-velar before a front vowel, where other dialects replaced it with Tau.
