ingenious

ingenious: [15] Ingenious used to be a more elevated term than it is today. To begin with it meant ‘highly intelligent’, but already by the 16th century it was starting to come down in the world somewhat to ‘cleverly inventive’. It comes, partly via French ingénieux, from Latin ingeniōsus, a derivative of ingenium ‘natural talent, skill’ (a word which, like English gene, generate, genital, etc, goes back ultimately to Indo-European *gen- ‘produce’, and was also the source of English engine).

Its formal similarity to the distantly related ingenuous has led in the past to its being used for ‘honest, open, frank’, and indeed its semantic derivative ingenuity ‘quality of being ingenious’ [16] belongs etymologically to ingenuous.

In a sense of "crafty, clever, skillful" Middle English had enginous (mid-14c.), from Old French engeignos, also engineful "skillful (in war)" (c. 1300). Related: Ingeniously; ingeniousness.
