stigweard

Old English stigweard combined stig (house, hall) and weard (guardian, keeper). The stigweard was the official who managed a great household — overseeing the staff, controlling the food stores, managing finances, and ensuring the smooth running of a noble establishment. The position was important: a poorly managed household was a sign of its lord's inadequacy.

As English feudal society developed, the steward's role expanded. The Lord High Steward of England was one of the great offices of state — the official who organized major royal ceremonies. The earldom of Steward became the surname Stewart (or Stuart) in Scotland, where the royal house that produced Mary Queen of Scots and the later British monarchs took their dynasty's name from a stewardship position.

The word spread to every domain where management was needed: estate stewards managing large landholdings, ship stewards managing crews and supplies, shop stewards managing workers' interests in industrial disputes, airline stewards and stewardesses managing passenger cabins. Each use preserved the core meaning: someone managing a domain on behalf of those they serve.

The term stewardship — management in trust, care of something belonging to others — has acquired ecological significance in contemporary usage. Stewardship of the environment, stewardship of natural resources: the Old English hall-guardian is now invoked to describe humanity's management of the planet. The mead-hall keeper became a model for sustainable development.
