New words in Webster's

SPRINGFIELD (Massachusetts) - DO YOU use a sock puppet to secretly keep track of your frenemies? Plan to spend your staycation watching vlogs and webisodes? Or perhaps you plan to signal a flash mob for a quick bite of shawarma.

If you're not entirely certain what all that means, turn to the latest edition of the Merriam-Webster's Collegiate Dictionary, which has added about 100 new words that largely reflect changing trends in American society.

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.
