"Back in 2000, the ADS (American Dialect Society) not only named the Word of the Year but chose also the Word of the Decade, the Word of the Century, and the Word of the Millenium. The Word of the Decade was the web, which beat among others the prefix e-, the combining form Franken-, ethnic cleansing, senior moment, and the slangy way "very" (as in way cool). The Word of the Century was jazz, an interesting choice, considering that it outmatched such weighty terms as DNA, media, melting pot, modern, and World War, though it certainly deserved to rout the other, rather lightweight nominees, cool, teenager, T-shirt, and teddy bear. The Word of the Millenium was the pronoun she, which did not exist before the year 1000 (it replaced heo, which was too often confused with he). A close runner-up was science."
