Confidence
Established
Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Latin (aequus)

Pronunciation

  • Classical: [ɪˈniː.kʷɪ.taːs][1]
  • Ecclesiastical: [iˈniː.kʷi.tas][1]

Forms

inīquitās f (genitive inīquitātis); third declension[1]

Etymology

It is formed from inīquus (“uneven, unfair”) with the suffix -tās.[2][1][3] ⟨Inīquus⟩ is the negative of aequus (“level, fair”), which de Vaan traces to ⟨*aikwos⟩ but finds no convincing etymology for.[1][4]

Earliest recorded meaning

Köbler gives Cicero as its first author.[3]

Semantic evolution

It is unevenness of the ground, as Caesar's disadvantage of the terrain, and inequality of size or amount, as an inscription's unequal measures and weights, or the uneven distribution of work in Columella.[2][5] Figuratively it is unfairness or hostile prejudice, as Claudius Quadrigarius on the unfairness of the gods, under whom the worse are safer, and the adverse nature of circumstances, as Curtius' “adversity of the time”.[2]

In the Bible and Church Latin it became iniquity, sin and injustice, and in medieval Latin also a crime.[6][7][1]
