A majordomo is a person who speaks, makes arrangements or takes charge for another. Typically, this is 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.

A majordomo may also, more informally, be someone who oversees the day-to-day responsibilities of a business enterprise. Historically, many institutions and governments – monasteries, cathedrals, and cities – as well as noble and royal houses also had the post of majordomo, who usually was in charge of finances.
