Forms
iūstē (comparative iūstius, superlative iūstissimē)[1]
Etymology
It is from Latin iūstus (“just, lawful”) + -ē.[2][1] De Vaan derives iūstus from iūs (“law, right”), whose old form is seen in the Forum inscription's ⟨iouestod⟩, and traces iūs to an s-stem Proto-Italic *jowos.[3]
Earliest recorded meaning
The OLD's earliest example is in the Rhetorica ad Herennium, of deeds done with the best of reasons.[2][4] Köbler gives Cicero as its first author.[4]
Semantic evolution
It means in accordance with the law, as Cicero speaks of accusing someone lawfully and dutifully, and in accordance with justice, rightfully or deservedly.[2] It is also justifiably, with good reason, and in a spirit of justice, uprightly, as when Cicero asks whether living justly is useful.[2][5] Gellius uses it of the full prescribed term, of babies carried the full time in the womb.[2]
