Many decades ago, Mrs. Gentry and Mr. Halferty put up with an inquisitive kid’s classroom questions about American democracy and the workings of government.

I did not imagine back then how the meaning of some words could take on such importance in government. Take, for example, a much-talked-about word in Iowa last week, vexatious. It means abrasive, aggravating, annoying, irritating or nettlesome.
