Pronunciation

  • IPA (Ecclesiastical): [in̠ʲˈd͡ʒɛː.nu.us][1]

Forms

ingenuus (feminine ingenua, neuter ingenuum); first/second-declension adjective[1]

Etymology

It is from in- “in” and the root of gignō “to beget”, with the suffix -uus, perhaps through ⟨*genowos⟩.[2][1]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of the freeborn.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant native, natural, as in Lucretius, and in Plautus born of a free father, freeborn.[2] In Cicero it meant befitting a freeborn person, liberal, gentlemanly.[2] Etymonline adds the senses noble in character, frank, upright, candid.[4]

In Ecclesiastical Latin it meant native, natural, inborn.[5] Medieval Latin used it for noble, and also for freed, a freedman.[6] British Medieval Latin used it for innate, natural.[7] It was borrowed into Italian ingenuo and French ingénu, and gave English ingenuous in the 1590s, and French ingénue gave English ingenue in 1848.[1][4]
