The English language is a living, breathing, expanding phenomenon. Year after year, new words are coined as time, technology, world events, and fashions dictate—but fads are fickle. If the public interest wanes for a particular trend, or world events are relegated to a foggy past, many associated words will be lost and forgotten. Still, others remain as mainstays to our evolving language and how we use or misuse it.
With this in mind, we've grabbed a handful of newly minted words from the years they were coined, from 1920–present. Their definitions come from Merriam-Webster Time Traveler site, except for the years 2012–13 and 2017–18.
Words hold a fascination for all, from what they convey to the feelings and thoughts they evoke. Some may jog memories of incidents or events long past, while others forgotten throughout the years may be wholly new to some.
Read on for the words—and the events that may have triggered them—that reached popularity the year you were born.
