Forms

iniūstitia f (genitive iniūstitiae); first declension[1]

Etymology

It is from Latin iniūstus (“unjust”) + -ia.[2][3] The adjective is a compound of in- (“not”) and iūstus (“just”),[4][1] which de Vaan explains as a derivative of iūs2 (“law”), tracing the noun to an s-stem going back to Proto-Indo-European *h₂oi-u (“vital force, eternity”).[5]

Earliest recorded meaning

The TLL finds it once in Plautus,[3][6] who in the Mercator speaks of the “faithlessness and injustice of pimps” (perfidiam, iniustitiam lenonum).[3]

Semantic evolution

Terence uses it twice, once of a man's harshness, which the TLL glosses as inhumanity.[3][7] Cicero has it often in his philosophical works and calls it the opposite of iūstitia, justice; in the De officiis he distinguishes two kinds of injustice.[3][7] After the comic poets it no longer appears in poetry.[3] From Tertullian on it is frequent, especially in the scriptures and church writers, although Jerome preferred inīquitās in his translations;[3][7] Lactantius has the plural, “injustices”.[3][7] In Ecclesiastical Latin it means injustice, sin or iniquity,[8] and in medieval Latin also a wrong or prejudice done to someone, and an act of violence.[9] Through Old French it gave English injustice in the late 14th century.[4]
