Inherited from Middle English cedule, from Middle French cedule (whence French cédule), from Old French cedule, from Late Latin schedula (“papyrus strip”), diminutive of Latin scheda, from Ancient Greek σχέδη (skhédē, “papyrus leaf”), from Proto-Hellenic *skʰíd͏̌d͏̌ō, from Proto-Indo-European *skid-yé-ti, from *skeyd- (“to divide, split”). Doublet of cedula and cedule. This word was historically pronounced /ˈsɛdjuːl/, /ˈsɛdʒuːl/; the pronunciations with /ʃ/ and /sk/ are due to the spelling (the latter may have been reinforced by learned influence); compare schism.
