Wyverns are often depicted as having the tail of a viper—a venomous snake—and that fact is reflected in the etymology of “wyvern”: it comes ultimately from the Latin word “vipera,” which means “viper.” (“Vipera” is also, of course, the source of our word “viper.”) The creature the wyvern most closely resembles, however, is the also-mythical dragon. “Dragon” is a much older word—it has been in use since the 13th century, while “wyvern” dates to the early 17th—but it too has snakes in its history. The word originally referred not to the lizard-like creature we imagine today but to a huge serpent.
