Etymology: The root is the Latin "communis," meaning "common" or "shared." The verb built on it, "communicare," meant "to share, impart, or make common," so its original sense was closer to putting something into joint possession than to passing along a message. The same root gives us "community" and "communion" as well as "communicate." The "non-" at the front is the Latin negative "non," meaning "not." Attached to "communicator," it describes someone who does not perform the sharing role. The "-or" ending is an agent suffix, marking a person who performs an action, so the base form names one who conveys ideas or information. This is a transparent English formation, built from a prefix, a verb stem and a suffix, rather than a single term borrowed whole from another language.
