The seventh edition of The Official Scrabble Players Dictionary will be available later this month. Last updated in 2018, it contains around 500 new words that have come into common usage. All the new words are in the Merriam-Webster dictionary, which is updated constantly. You may or may not be familiar with them. Here's a few interesting examples.
adulting
deadname
dox
dumpster (formerly a brand name)
eggcorn
embiggen
fauxhawk
hygge
subtweet
unfollow
unsub
yeehaw (they admit this is not new)
zonkey
zoomer
If you play Scrabble, you've probably already tried to use these words, and you could get away with it if no one in the room had an official Scrabble Dictionary. Until you get your new copy, you can refer any protesters to this post. A lot of words have been deleted from the new edition, mainly racial and ethnic slurs and otherwise offensive words. As always, the Scrabble tournament edition is somewhat different. See more of the new words in an AP article. -via Metafilter
