Etymology: "Controverts" is the third-person singular form of "controvert," so its origin is the verb's. The verb was borrowed from Medieval Latin "contrōvertere," built from Latin "contrō-," meaning "against," and "vertere," meaning "to turn." The image underneath is literal: to controvert something is to turn against it, setting yourself face to face with a claim and pushing back on it. The Latin "vertere" is the same root that gives English "verse," "version," "convert," and "reverse," all of which share the sense of turning. Adding "contrō-" gives the turning a direction: the arguer turns to face the opponent's assertion rather than accepting it. Over time the physical sense of turning around faded, leaving the abstract sense of disputing a point.
