Electrelocution

In 1889, there rose a situation that showed in what threatening depths the American genius [for neologism] was floundering. Notes & Queries, in May 11, appealed to its readers: "A New Word Wanted.—Correspondents of American Notes and Queries are requested to send suggestions for a word that shall express execution by electricity." The appeal was accepted as a linguistic challenge not only by the somewhat scholarly readers of Notes & Queries, who began juggling classical roots, but also by others whose response shows a deliberate departure from traditional spontaneity. The North American Review, plunging with zest into the etymological pool, suggested electrolethe. The Saginaw Evening News introduced electricide. The Century Magazine, noting some use of electricution, termed it "recent and colloquial." In the Congressional Record of August 9, 1890, reference was made to electrical execution as the Kemmler process, dubiously honoring not its inventor but the first criminal to experience its final solution. . . Electrocute, a hybrid of Greek electro- plus Latin –cute, eventually won out. But the folk had the last word. Before long, criminals were simply sent to the chair; and everyone, in the American way, got the picture.
