Etymology: "Communicate" comes from Latin "communicare," meaning "to share" or "to make common," built on "communis," "common." Its oldest English sense was about sharing something, such as a meal or a sacrament, and only later did it come to mean passing along news or information. The "de-" prefix in "decommunicate" reverses that sense: where communicating makes something shared, decommunicating removes a person from the shared life of a group. The prefix and the verb are both Latin in origin, and the verb is a formal, rare coinage built from them rather than a common everyday term. Its meaning is close to "excommunicate," which shares the same root and similarly describes cutting someone off from a community, but "decommunicate" is the less familiar variant and can apply to any cutting off of dialogue or association, not only religious exclusion.
