- Ultimate origin
- Proto-Indo-European (*med-o-)
Forms
moderātor m (genitive moderātōris, feminine moderātrīx); third declension[1] The feminine is moderātrīx.[1]
Etymology
It is from Latin moderor (“to regulate, control”) + -tor.[2][1] moderor is built on the stem of modus (“measure”),[1] which de Vaan traces to Proto-Italic *medo- (“measure, judgement”) and Proto-Indo-European *med-o- (“measure”).[3]
Earliest recorded meaning
Naevius has it first,[4][2] in a tragedy: trionum hic moderator rusticus, “this country driver of plough-oxen”.[2]
Semantic evolution
It is first someone who guides or handles something: Ovid has a driver of horses and, for an angler, the “guider of the rod”, and Claudian a wool-comber.[5] More often it is one who controls or governs: Cicero has the ruler and director of so great a work, and asks where the managers of the public meetings were.[5][2] It is also one who restrains, as Cicero's shame, the check on desire, and in Ovid there is no one to put a limit to an evil.[2][5] Martial has it of a tutor of the young.[5] Church Latin uses it of a guide, director or adviser, a confessor and a religious superior.[6]
