The lexicographers working for Merriam-Webster aren't snobs about words. They understand better than anyone that language is constantly evolving, and even the silliest slang deserves a spot in the dictionary if it's used widely enough. After closely monitoring changes in the lexicon, Merriam-Webster added 455 terms to the dictionary in October 2021.

Many of the newly recognized words reflect our current times. Coronavirus-related terms such as super-spreader, breakthrough, and vaccine passport have become common enough to warrant their own entries. Some words aren't directly linked to COVID but are indicative of the pandemic's impact on culture. For example, Merriam-Webster's dictionary now includes digital nomad, as many people have shifted to remote work.

As is the case every year, many of the additions originated on the internet. Merriam-Webster users can now look up the definitions of TBH, FTW, and copypasta through the resource. The new list also includes many terms that have been around for a while, like chicharron and fluffernutter. You can view 20 notable entries from the new batch of words below.
