## Origin

From Middle English "fraccioun" ("a breaking"), borrowed via Anglo-Norman and Old French from Medieval Latin "fractio" ("a fragment, portion") and earlier Latin "fractio" ("a breaking into pieces"). This came from "fractus," the past participle of "frangere" ("to break"), from Proto-Indo-European *bʰreg-, which also gives English "break."
