Sara Palin's Contribution in 2010

OUP USA 2010 Word of the Year: Refudiate

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.” ~Oxford University Press Blog
