Forms

ingénu (feminine ingénue, masculine plural ingénus, feminine plural ingénues)[1]

Etymology

It is borrowed from Latin ingenuus (“native, born of free parents, frank”),[2][3][4][5] formed from in- (“in”) and the root of gignō (“to beget”).[3][6][7] The French senses follow the two Latin ones: “freeborn” and, morally, “sincere, worthy of a free man”.[2][3] It is recorded once in the 13th century before it was taken up again in 1480.[3][8]

Earliest recorded meaning

Apart from an isolated 13th-century record, it is first found in 1480, in a document in the archives of the Nord, in condicion ingenue “free status”.[2][3]

Semantic evolution

The legal sense “born free”, as opposed to freed, lived on in Roman law (les ingénus, 1690).[3] In the early 17th century the word took over the Latin moral sense and was applied to a person who speaks and acts with innocent frankness (1611, Cotgrave; as a noun in Molière, 1668: Quoy! tu fais l'ingénu!).[2][3] Bloch and Wartburg note that French added a shade of naivety of its own.[4] The favourable sense, still alive in the title of Voltaire's tale, aged: from the classical period on, the word suggested candour that is a little foolish.[3]

As a noun it passed into the language of the theatre (1829), with rôle d'ingénue and fausse ingénue.[3] The feminine went into English as ingénue in 1848.[9]
