From Middle English -dom, from Old English -dōm ("-dom: state, condition, power, dominion, authority, property, right, office, quality", suffix), from Proto-Germanic *-dōmaz (“-dom”). Cognate with Scots -dom ("-dom"), West Frisian -dom ("-dom"), Dutch -dom ("-dom"), German -tum ("-dom"), Swedish -dom ("-dom"), Icelandic -dómur ("-dom"). Same as Old English dōm ("doom, judgment, sentence, condemnation, ordeal, judicial sentence, decree, ordinance, law, custom; justice, equity; direction, ruling, governing, command; might, power, dominion, supremacy, majesty, glory, magnificence, splendor, reputation, honor, praise, dignity, authority; state, condition").
