シリア文字
The Latin name ' derives from Ancient Greek ' (). This is ostensibly a Greek toponym based on a personal name, although it may be a Hellenized form of a local name, reconstructed as "Tisfōn" or "Tisbōn". In Iranian-language texts of the Sasanian era, it is spelled as "tyspwn", which can be read as "Tīsfōn", "Tēsifōn", etc. in Manichaean Parthian 𐫤𐫏𐫘𐫛𐫇𐫗, in Middle Persian 𐭲𐭩𐭮𐭯𐭥𐭭 and in Christian Sogdian (in Syriac alphabet) languages. The New Persian form is "Tisfun" ().
