“New” words in Webster’s 2007 Edition

Merriam-Webster:

Just two years after a majority of visitors to Merriam-Webster OnLine declared it to be their “Favorite Word (Not in the Dictionary),” the adjective “ginormous” (now officially defined as “extremely large: humongous”), has won a legitimate place in the 2007 copyright update of Merriam-Webster’s Collegiate® Dictionary, Eleventh Edition.
Merriam-Webster updates its best-selling Collegiate® Dictionary every year with a number of new words, senses, and variants. This year, the word “ginormous” was one of approximately 100 neologisms to make the cut, while many others will stay “closely watched” by our editors for possible inclusion in future revisions. (This, of course, begs the question: so just exactly how does a word get into the Merriam-Webster dictionary?)
