Did You Know?
If you've seen Western movies, you've seen rowels. The noun "rowel" names the circular, point-covered disk on the end of a spur that is used to urge powerful steeds to maximum speeds. But cowboys didn't invent rowels; knights in shining armor were sporting them even before the 12th century. English speakers of yore picked up the noun "rowel" from the Anglo-French "roele," meaning "small wheel" ("roele" is also an ancestor of the word "roulette"). By the end of the 1500s, "rowel" was also being used as a verb for any process of prodding or goading that was as irritating as being poked in the side with a rowel.
