The Global Language Monitor, which uses a math formula to track the frequency of words and phrases in print and electronic media, said "Obama" came third in the list with the surname of U.S. President Barack Obama used as the stem for other words.

"Bailout（救助，跳伞）" was listed fourth after the bank bailout was one of the first acts of the financial crisis, "evacuee（撤离者，疏散者）" came fifth in the wake of Hurricane Katrina devastating³ New Orleans, and "derivative（导数，衍生物）" featured sixth.

"Google," "surge," "Chinglish" meaning a hybrid⁴（混合，杂种） of Chinese and English, and "tsunami⁵," after the 2004 Asian disaster that left 230,000 people dead or missing, followed.

"Looking at the first decade of the 21st century in words is a sober（清醒的，稳重的）, even somber⁶（微暗的，阴森的）, event," said Paul JJ Payack, president of The Global Language Monitor.

"For a decade that began with such joy and hope, the words chosen depict⁷（描述） a far more complicated and in many ways, tragic⁸ time. Nevertheless（然而，不过）, signs of hope and renewal⁹ can be found in the overall lists."

Payack said the top phrase of the decade was "climate change" followed by "financial tsunami" and "Ground Zero."

Technology's impact on the past decade was reflected in the list with "Twitter," the micro-blogging site, one of the most used words while "blog" and "texting" featured on the list.

Hollywood continued to flex¹⁰ its muscle（显示力量）, with "slumdog" from the Oscar-winning film "Slumdog Millionaire," referring to child inhabitants of Mumbai slums, making its mark in global language. U.S. comedian¹¹ Stephen Colbert's "truthiness," defined as truth that comes from the gut¹²（勇气，肠） not books, came in at No. 25.
