Forms

rēgnātor m (genitive rēgnātōris); third declension[1] The TLL finds no plural, except in one restored passage.[2] Charisius sets a feminine rēgnātrīx beside it.[2]

Etymology

It is from Latin rēgnō (“to rule as king”) + -tor.[3][2] De Vaan lists it among the derivatives of rēx (“king”),[4] which he traces to Proto-Italic *rēg- (“king”) and Proto-Indo-European *h₃rēǵ-s (“ruler, king”).[4] Cognate with Old Irish rí (“king”) and Sanskrit राज् (rā́j-, “king”).[4]

Earliest recorded meaning

It is first found in Naevius, who calls Neptune ruler of the seas, Neptunum regnatorem marum.[3][5]

Semantic evolution

It is one who rules as king, a lord;[3] Lewis & Short call it poetic.[5] It is often applied to gods: Plautus has the ruler of the gods, Virgil the ruler of high Olympus, and Seneca the ruler of the strait.[3][5] Tacitus has the god who rules over all, regnator omnium deus.[5] It is also used of persons and things supreme in their kind, as Virgil's Tiber, the horned river, ruler of the waters, and Statius' Pindar, ruler of the lyric band.[3][5] Plautus uses it plainly of Agathocles, who was king in Sicily, and Martial of the owner of a small field.[5] Donatus notes that a king is sometimes called regnator, sometimes dominus.[2] In Church Latin it is a ruler or governor.[6]
