means A person who formally conducts or presides over a ceremony — most often a wedding, sometimes a funeral or other rite — guiding it from start to finish.

from Traces back to Latin 'officium,' meaning duty, service, or a dutiful act — the same root that gives us 'office' and 'official.' By the 1600s English had 'officiate,' meaning to perform the duties of a role or ceremony, and 'officiator' followed as the agent noun: the one who actually does the officiating. So at its root, the word is simply about duty performed — it just happens to have been drafted, in modern times, into weddings run by newly minted internet ministers.
