"New START is not explicitly about improving relations with a former cold-war adversary, but rather reducing stockpiles of dangerous weapons, some of which could be at risk of falling into terrorists' hands." -- From an article by Howard LaFranchi in The Christian Science Monitor, December 20, 2010 Did you know? If you've ever had someone turn on you and become your adversary, you've inadvertently lived out the etymology of "adversary." The word is from the Latin adjective "adversarius" ("turned toward" or "antagonistic toward"), which in turn can be traced back to the verb "advertere," meaning "to turn to." "Advertere" itself derives from "ad-" and "vertere" ("turn"), and "vertere" is the source of a number of English words. Along with obvious derivatives like "inadvertently" and "adverse" are some surprises, such as "anniversary," "prose," and "vertebra," among others.
