“Ping” got a new definition in Merriam-Webster in 2017 when the dictionary added the sense of contacting someone via a brief digital message.

People love to point to the rise of “selfies” in the 2010s as an indication of the decline of society. In 2013, Oxford Dictionaries named “selfie” as the word of the year.
