Producing the intended effect is from the 1590s (1598 in the OED),[2][5] and concerned with manual or practical work from 1624.[5] Relating to surgical operations is from 1783.[5] Of words, containing the key point, as the operative word, is from 1926.[5] The noun, a worker or artisan, is from 1809,[2] and a secret agent from 1930, probably from the Pinkerton agency's use of it for its private detectives (1905).[2]
