Where it comes from
From Middle French siphon, from Old French sifon, from Latin sīphō, from Ancient Greek σίφων (síphōn, “pipe, tube”), of uncertain origin; possibly related to Latin tibia (“pipe, flute of bone”), with the irregular forms suggesting a non-Indo-European loan source, perhaps of the shape *twi-, *twibh.
