so·phis·ti·cate: late Middle English (as an adjective in the sense âadulteratedâ, and as a verb in the sense âmix with a foreign substanceâ): from medieval Latin sophisticatus âtampered withâ, past participle of the verb sophisticare, from sophisticus âsophisticâ. The shift of sense probably occurred first in the adjective unsophisticated, from âuncorruptedâ via âinnocentâ to âinexperienced, unculturedâ. The noun dates from the early 20th century. ~ Oxford English Dictionary
