Etymology: "Officiator" is a plain formation: the verb "officiate" with the agent suffix "-or" added to it, so it names the person who performs the officiating. The suffix has a long pedigree, passing from Latin "-tor" through Old French and into Middle English as "-our" before settling into the modern "-or" spelling in English. The verb it builds on, "officiate," comes from the medieval Latin "officiare," which means to perform a function or duty, and it is itself rooted in the Latin "officium," a word for a duty or service. The suffix ending is the same one found in older English agent nouns such as "actor" and "doctor," so "officiator" follows a pattern English speakers have used for centuries.
