In school, many of us were sent to dictionaries to look up words we didn't know.
Now, dictionaries are coming to us, filling themselves up with terms that may already feel overly familiar.
More than 150 new words and definitions have been added to the Merriam-Webster's Collegiate Dictionary, the publisher announced Monday. The list includes selfie, hashtag, big data and unfriend.
"So many of these new words show the impact of online connectivity to our lives and livelihood," Peter Sokolowski, a Merriam-Webster editor, said in a statement.
