Merriam-Webster’s new words include ‘unfriend,’ ‘spoiler alert,’ ‘gamification’

If you quite understandably unfriend someone who tries to catfish you via social networking, Merriam-Webster officially has your back.

Those three terms—”unfriend,” “catfish,” and “social networking”—are among the 150 new words and phrases that the publisher has officially added to the new edition of its collegiate dictionary. They’re part of a contingent of social media-related terms that have been added. Others include “gamification,” “crowdfunding,” “hashtag,” “selfie,” and “tweep.”
