Etymology: "Oesophagi" is simply the plural of "oesophagus," so the word's story is really the story of its singular. The Ancient Greek "oisophagos" was built from two verb forms: "oisō," the future of "pherō" meaning "to carry," and "ephagon," the past form of "esthiō" meaning "to eat." Put together, the name describes the thing that carries food along, a literal description of a tube doing a single job. The Greek compound stayed in the scientific vocabulary of the classical tradition and reached English through Latin and medical writing, where it was used for the gullet. Its plural, "oesophagi," follows the Greek pattern of forming plurals in "-i," the same ending seen in words like "alumni" and "cacti," which is why it appears in technical and medical texts.
