The story
- Ancient Greek · derived fromσυλλαμβάνω“to put together”
- Ancient Greek · derived fromσιττύβα“parchment label; table of contents”
- Medieval Latin · borrowed fromsyllabus“list”
- English todaysyllabus
Borrowed from Medieval Latin syllabus (“list”), which arose from accusative plural syllabōs appearing as a corruption of sittybās (accusative plural of sittyba, from Ancient Greek σιττύβα (sittúba, “parchment label; table of contents”)) in a 1470s edition of Cicero's “Ad Atticum” IV.5 and 8, influenced by the stem of Ancient Greek συλλαμβάνω (sullambánō, “to put together”).
