c.1400, "use or employment of sophistry," from Medieval Latin sophisticationem (nominative sophisticatio), from sophisticare "adulterate, cheat quibble," from Latin sophisticus "of sophists," from Greek sophistikos "of or pertaining to a sophist," from sophistes "a wise man, master, teacher" (see sophist). Meaning "wordly wisdom, refinement, discrimination" is attested from 1850.
