According to a dictionary prepared by Thomas Blount in 1656, a cavalier was "a knight or gentleman, serving on horseback, a man of arms." That meaning is true to the history of the noun, which traces back to the Late Latin word "caballarius," meaning "horseman." By around 1600, it had also come to denote "a roistering swaggering fellow." In the 1640s, English Puritans applied it disdainfully to their adversaries, the swashbuckling royalist followers of Charles I, who sported longish hair and swords. Although some thought those cavaliers "several sorts of Malignant Men,… ready to commit all manner of Outrage and Violence," others saw them as quite suave -- which may explain why "cavalier" can be either complimentary or a bit insulting.
