Etymology
It is formed from in- (“not”) and expiō (“to atone for”) with the suffix ⟨-bilis⟩,[2] or from in- and expiābilis.[1][3] expiō is a compound of ex- and piō (“to appease”), from pius (“dutiful”),[4] which de Vaan traces to Proto-Italic *pwījo- and Proto-Indo-European *puH-io- (“purifying”).[5] Cognate with Umbrian pihatu (“to reconcile”).[5]
Earliest recorded meaning
Köbler dates it from Cicero,[4] who speaks of unheard-of rites profaned by an inexpiable crime, inexpiabili scelere.[2]
Semantic evolution
Of offences it means that cannot be atoned for, inexpiable;[2] Cicero has an inexpiable religious obligation.[6] Of punishments it is that cannot be escaped by expiatory rites, as when Cicero reports the cry that inexpiable punishments await those who harm an animal.[2] Of persons and feelings it is that cannot be appeased, implacable: Cicero writes of Caesar showing himself implacable and irreconcilable to him.[2] Livy speaks of an implacable war and of the Romans' implacable hatred of Hannibal, and Quintilian also uses it of war.[6] Isidore of Seville explains it as what is never expiated or purged, and glossaries as what cannot be cleansed, or one not moved by prayers.[3]
