Is your doggo ‘grammable?

Merriam-Webster has added 690 new words to its dictionary – including newsworthy terms like UAP (unidentified aerial phenomenon) and more buzzworthy ones like doggo and chef’s kiss.

"These new additions have demonstrated widespread use over time, and offer a window into the world today," Merriam-Webster said in a news release.

Sports fans will appreciate beast mode ("an extremely aggressive or energetic style or manner that someone (such as an athlete) adopts temporarily (as to overpower an opponent in a fight or competition") and kayfabe, a tacit agreement familiar to pro wrestling enthusiasts.
