Forms

immoderātē (comparative immoderātius, superlative immoderātissimē)[1][2] It is also spelled ⟨inmoderātē⟩.[1]

Etymology

It is from Latin immoderātus (“unrestrained, immoderate”) + -ē.[1][3] The adjective is in- (“not”) and moderātus (“restrained, moderate”), from moderor (“to control, restrain”), which de Vaan lists among the derivatives of modus (“measure”);[4] that noun goes back to Proto-Italic *medo- (“measure, judgement”) and Proto-Indo-European *med-o- (“measure”).[4] Cognate with Umbrian meřs (“law”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[5] who in De natura deorum says that the tongue shapes the voice that is poured out without control.[1][2]

Semantic evolution

Its first sense is without rule or control:[1][6] Cicero uses it of moving at random and without rule, the Bellum Africum of troops now withdrawing behind the gates and now coming out without plan, and Quintilian of breath let out without control.[1][6]

More often it means without restraint, immoderately or intemperately.[1][7] Cicero complains of people who abuse his good nature immoderately and ungratefully and writes of living immoderately and intemperately;[1][2] Livy, Valerius Maximus, Seneca and Tacitus use it too,[1] and Suetonius has the comparative of bidding too high at an auction.[6] The Historia Augusta has the superlative of rejoicing beyond measure.[6]

British medieval writers used it of behaviour, as Goscelin of mourning so immoderately, and of physical conditions, as Gerald of Wales of the wind.[8]
