constable: [13] The late Latin comes stabulī was an officer in charge of the stables (comes is the source of the English title count, and stabulum is the ancestor of English stable). From the comparatively lowly status of head groom, the job gradually grew in importance until Old French conestable was used for the principal officer of the household of the early French kings. In the 14th century the title was adopted for the Constable of England. On a less exalted level, the word has also been used since the 14th century for someone appointed to uphold law and order, and was applied to police officers when they were called into being in the 1830s. => count, stable[constable etymology, constable origin, 英语词源]
