Origin & History of “stable”

English has two distinct words stable, but both come ultimately from the same source: the Indo-European base *stā- ‘stand’, ancestor also of English stand. The adjective stable (13th c.) comes via Old French estable from Latin stabilis ‘standing firm’, which has also given English establish, stability (15th c.), and stabilize (19th c.). It was formed from the base *stā-, as was Latin stabulum ‘standing-place’, hence ‘enclosure for animals’, which English acquired via Old French estable as stable (13th c.). The corresponding Germanic formation, also based on *stā-, is stall. A constable is etymologically an ‘officer in charge of stables’.
