Etymology, a subject rarely studied on our campuses, enjoys the respect of many people, even though they persist in calling it entomology. Human beings always want to know the origin of things, but sometimes etymology is made to carry double, like the horse in O. Henry’s story “The Roads We Take.” For instance, it is sometimes said that etymology helps us to use words correctly. Alas, it very seldom does so. If someone asks us about the meaning of the adjective debonair and is not only informed that a debonair man is genial, suave, and so forth but also that the adjective goes back to the French phrase de bon aire “of good disposition (nature),” this may help.
