Frenemy, locavore among new words in Webster's - Yahoo! News
John Morse, president and publisher of the Springfield-based dictionary publisher, said many of this year's new words are tied to changes in technology, increasing environmental awareness and aging baby boomers' concerns about their health and have become part of the general lexicon.
"These are not new words in the language, by any means," Morse said. "(But) when words like 'neuroprotective' and 'cardioprotective' show up in the Collegiate, it's because we've made the judgment that these are not just words used by specialists. ... These really are words now likely to show up in The New York Times, in The Wall Street Journal."
There are words such as locavore (one who eats foods grown locally), frenemy (someone who acts like a friend but is really an enemy), waterboarding (an interrogation technique use to induce the sensation of drowning), vlogs (a blog that contains video material) and webisode (a TV show that can be viewed at a Web site).
There's also flash mob (a group of people summoned electronically to a designated spot at a specified time to perform an indicated action before dispersing) and green-collar (involving actions for protecting the natural environment).
Some words that just now made the cut have been around for generations. The term "sock puppet" — a false online identity used for deceptive purposes — was tracked to 1959 but has taken on new popular use with people using fake IDs on social networking sites.
