Merriam-Webster has just released the list of the some 100 new words added to its Collegiate Dictionary, Eleventh Edition. (来源：英语麦当劳－英语学习门户 http://www.EnglishCN.com)
"Our language evolves in many ways," says John Morse, president and publisher of Merriam-Webster. "People enjoy blending existing words, like combining 'stay' and 'vacation' to make staycation. "
"Staycation is a good example of a word meeting a need and establishing itself in the language very quickly. Our earliest record of use is from 2005, but it seems to have exploded into popular use in 2007."

Many of the new additions reflect the importance of the environment (carbon footprint, green-collar), government activities (waterboarding), pop culture (flash mob, reggaeton), and online activities (sock puppet, vlog, webisode).
The updated dictionaries define "waterboarding" as "an interrogation technique in which water is forced into a detainee's mouth and nose so as to induce the sensation of drowning" . Other words added to the new dictionary include "Webisode," defined as "an episode especially of a TV show that may or may not have been telecast but can be viewed at a Web site."
