The History of Inveterate

Despite how it may seem at first glance, inveterate has nothing to do with lacking a spine. That’s invertebrate, which came into English in the early 19th century from New Latin, the Latin vocabulary used in scientific description and classification. Inveterate, on the other hand, is a true veteran of the English language, with a membership card dating to the 15th century. Like veteran, inveterate ultimately comes from the Latin adjective vetus, which means "old." (In times past, inveterate had among its meanings "old.") The more direct source of inveterate, however, is the Latin adjective inveteratus, with which it shares the meaning "firmly established by long persistence." Today inveterate most often describes someone who so frequently or invariably engages in a particular habit or attitude as to be regularly identified with that habit or attitude, as when political columnist Jamelle Bouie observed "The truth is that our best presidents—or at least our most successful ones—have been inveterate flip-floppers, willing to break from unpopular positions, move with political winds, and adjust to new complications."
