Did you know?
You may suspect that a connection exists between "scission" and "scissors," but, actually, their etymologies are sharply divided. "Scission" traces to the Latin verb scindere ("to split" or "to cut"). "Scissors," on the other hand, comes from an entirely separate Latin verb that also means "to cut" - "caedere." The Middle English word for the cutting instrument was "cisours" or "sisoures," which comes from Middle French cisoires. An "sc" spelling appeared only in the 16th century when, apparently, the word for the cutting instrument was mistakenly taken to have derived, like "scission," from "scindere."
