ingenuity

Etymology

It is borrowed from Latin ingenuitās (“the condition of a freeborn person; noble-mindedness, frankness”),^{[2][3][4][5][6][7]} perhaps through French ingénuité or Italian ingenuità, which the OED names as possible immediate sources;^[2] Etymonline takes it from French and directly from Latin.^[3] The Latin noun is from ingenuus (“native, freeborn; frank, noble”),^[2][5][3] formed from in- (“in”) and the root of gignō (“to beget”),^[3][8] from Proto-Indo-European *gene- (“to give birth, beget”).^[3] It is thus the abstract noun of ingenuous, but its present meaning, inventive skill, comes from confusion with ingenious;^{[2][3][9][6][5][10]} the OED observes that this use is found only in English.^[2]

Earliest recorded meaning

Honour, nobility: Etymonline dates the word to the 1590s,^[3] and Merriam-Webster to about 1592, in the sense of candour.^[8] The OED's first quotations, in Florio's dictionary of 1598, mean the condition of being freeborn and nobility of character.^[2]

Semantic evolution

At first the word belonged to ingenuous, meaning freeborn status, nobility of mind (to 1716) and frankness or candour (from 1614), a sense now rare.^[2][7] In the 17th century ingenious and ingenuous were so often confused, even in Shakespeare, that ingenuity came to serve as the noun of ingenious,^[3][2] first as intellectual talent or genius (1600, in Ben Jonson) and good sense,^[2] and since 1649 as skill in inventing or contriving things, now its only common sense.^[2][3] Middle English had used ingeniosity for this, and the native word was craftiness.^[3] Johnson (1755) still gave "openness; fairness; candour" first, and marked the sense "wit; invention; genius" as coming from ingenious.^[11] French ingénuité went the other way, towards graceful simplicity (compare ingenue), and French uses ingéniosité for cleverness.^[3]
