moderor (present infinitive moderārī or moderārier, perfect active moderātus sum); first conjugation, deponent[1]
Etymology
It is built on the same lost neuter ⟨s⟩-stem as modestus, from Proto-Indo-European *med- (“to measure”), not directly on modus.[1][2][3] An active ⟨moderō⟩ is also found, and Lucretius has ⟨moderārier⟩.[3][4]
Earliest recorded meaning
The OLD's earliest citations are from Plautus, of governing, restraining and tempering.[3] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It meant to direct, guide, as a ship or chariot, and to handle, control, as in Cicero and Ovid.[3] From Plautus it meant to govern, rule, and of things to be the controlling factor.[3] It meant to restrain, check, and to make less violent, temper, moderate, as in Plautus.[3] It also meant to regulate, arrange, as in Pliny.[3] Lewis and Short give its basic sense as to set a measure, set bounds to a thing.[4]
In Ecclesiastical Latin it meant to govern, guide, regulate, direct, advise.[6] Its participle moderātus gave English moderate in the late 14th century, first of weather.[7]
