Followers of Sarah Palin’s Twitter account will undoubtedly recognize the New Oxford American Dictionary’s Word of the Year for 2010:
refudiate verb used loosely to mean “reject”: she called on them to refudiate the proposal.
Refudiate: A Historical Perspective
An unquestionable buzzword in 2010, the word refudiate instantly evokes the name of Sarah Palin, who tweeted her way into a flurry of media activity when she used the word in certain statements posted on Twitter. Critics pounced on Palin, lampooning what they saw as nonsensical vocabulary and speculating on whether she meant “refute” or “repudiate.”
From a strictly lexical interpretation of the different contexts in which Palin has used “refudiate,” we have concluded that neither “refute” nor “repudiate” seems consistently precise, and that “refudiate” more or less stands on its own, suggesting a general sense of “reject.”
Although Palin is likely to be forever branded with the coinage of “refudiate,” she is by no means the first person to speak or write it—just as Warren G. Harding was not the first to use the word normalcy when he ran his 1920 presidential campaign under the slogan “A return to normalcy.” But Harding was a political celebrity, as Palin is now, and his critics spared no ridicule for his supposedly ignorant mangling of the correct word “normality.”
In addition, forming a word by merging two together (technically called “a blend”) can be useful and has a long established pedigree, as evidenced by words we take for granted in modern usage but which started life as blends: for example, brunch, acupressure, smog, and motel.
