A person who manages or oversees a large estate or household, often acting as a chief servant or organizer.
The majordomo ensured that all the guests were well taken care of during the event.
Majordomo → It is formed from "major" (from Latin "maior", meaning greater or larger) and "domo" (from Latin "domus", meaning house). The word "majordomo" refers to a person who is in charge of a household or estate, essentially the chief steward or head servant of a larger household.
Think of someone who is the 'greater' ('major') authority in a 'house' ('domus') — that's why a majordomo is the chief steward of a household.
