ingenuous: [16] Etymologically, ingenuous means ‘inborn’. English acquired it from Latin ingenuus, which was composed of the prefix inand the element *gen-, denoting ‘production, birth’. This was originally used for ‘born in a particular place, native, not foreign’, but it soon began to take on connotations of ‘freeborn, not a slave’, and hence ‘of noble birth’.
Metaphorical transference to qualities thought characteristic of the nobility – uprightness, candour, straightforwardness, etc – soon followed, and that was the word’s semantic slant when English acquired it. By the 17th century, however, it had started to slide towards ‘artlessness, innocence’ (a sense reflected in ingénue, borrowed from French in the 19th century). => gene, general, generate, genital, ingénue
ingenuous (adj.)
1590s, "noble in nature," from Latin ingenuus "with the virtues of freeborn people, of noble character, frank, upright, candid," originally "native, freeborn," from in- "in" (see in- (2)) + gen-, root of gignere "beget, produce" (see genus). Sense of "artless, innocent" is 1670s, via evolution from "high-minded" to "honorably open, straightforward," to "innocently frank." Related: Ingenuously; ingenuousness.
