Usage

What does -dom mean? The suffix -dom denotes nouns for domains, collections of persons, rank or station, or general condition. It is often used in a variety of everyday and technical terms. The suffix -dom comes from Old English -dōm, meaning “statute, judgment, or jurisdiction.” Another descendant in modern English from this stem is doom, which today means “unavoidable ill fortune; ruin, death” but originally referred to a judgment or legal decision, especially an unfavorable one.
