Wikipedia Adds Some Color
Wikipedia gives a more complete picture:
“A majordomo is a person who speaks, makes arrangements, or takes charge for another. Typically, the term refers to the highest (major) person of a household (domūs or domicile) staff, a head servant who acts on behalf of the owner of a large or significant residence. Synonyms include castellan, concierge, chamberlain, seneschal, mayor of the palace, maître d’hôtel, head butler, and steward.
The term also refers, more informally, to someone who oversees the day-to-day responsibilities of a business enterprise.”
Fiction does a great job of providing some concrete examples:
In the 1994 film The Lion King, the character Zazu serves as majordomo (or as he introduces himself, “majordodo”) to Mufasa and later his son Simba after he became king.
Geoffrey Butler was the majordomo on the sitcom The Fresh Prince of Bel-Air.
Alfred Pennyworth is Bruce Wayne’s butler and father figure in the Batman universe. He has been called “Batman’s batman.”
The term “come[s] from the Medieval Latin major domus, meaning “chief of the house.” In its earliest uses, “majordomo” referred to the head steward of a royal household. The position was a high one with some relatively weighty responsibilities. Later, in the U.S., the word was used for the steward or overseer of a ranch. Since then, the word’s meaning has extended even further; today, “majordomo” can designate any person who takes charge of another’s affairs, be they business or personal.”
