Dictionaries are traditionally slow to adapt to changing cultural norms. This year, Merriam-Webster finally added “someone who is overly sensitive” to the definition of “snowflake,” now that the term has become a cliché. It allowed “purple” to refer to areas split between Democrats and Republicans, and you now have the dictionary’s endorsement when you use “peak” to talk about “peak television.”

America’s oldest dictionary also added long-established terms, from “free solo,” after an entire documentary on that style of rock climbing came out last year, to “gig economy,” coined in 2009.
