Why this word is great
INGENU — [Noun] An innocent, unsophisticated young man, untouched by cynicism or worldly artifice. From French ingénu ("guileless"), especially as used by Voltaire in L'Ingénu, from Latin ingenuus ("ingenuous"). Doublet of ingenuous. Unlike ingenue (which denotes a naive young woman) or naif (a general term for naivety, stripped of literary resonance), ingenu carries the weight of a specific, almost archetypal purity. He is the wide-eyed traveler stepping off the train into the city’s grime, the village boy who still believes in fairy tales, or the young artist whose first sketches are unmarred by self-doubt—a fleeting figure, destined to be either broken or hardened, but never unchanged.
