## Origin

**Meanings 1–4, 6–7, 12, 16–17, 24** — Latin cadō ("to fall, drop") gave the noun cāsus, meaning "a fall, a falling," and also "accident, event, occurrence, occasion." This passed through Old French cas ("an event") into Middle English cas.
**Meanings 5, 8–11, 13–15, 18–23** — Latin capiō ("to take, seize, hold") gave capsa ("box, bookcase"). This became casse in Old Northern French (Old French had chasse, "box, chest, case") and then Middle English case. Cash, chase, and chasse are doublets.
