The two-letter expression of disgust "ew" was the shortest word added to Scrabble's dictionary, joining a list of 106 other two-letter words, which are a vital part of Scrabble strategy.
"OK" was also added to the list after its capitalization prevented it from being used as a Scrabble word in the past.
"It used to be entered only as 'OK' or 'okay,'" Emily Brewster, an associate editor and lexicographer at Merriam-Webster told The New York Times.
"The ability to add seemingly random letters to existing ones will allow a player to enjoy far greater latitude in placing their words on the board, and will annoy opponents who think that the game should be played with words they recognize," the post stated.
The word "frowny" returned to the Scrabble dictionary after being removed from the 1961 edition, giving players another opportunity to play a valuable "Y" tile.
Also among the new additions were "bestie" -- although "BFF" is not yet playable -- and "twerk" along with other forms of the word such as "twerks," "twerked," and "twerking" but not "twerkings" and twerkery."
Two words which didn't originate in English and describe cultural items from other countries were also added to Scrabble's dictionary. First was the word "Qapik" -- a variant of the word gopik, which is defined as "a monetary subunit of the manat" of Azerbaijan, along with "arancini" an Italian style dish consisting of balls of cooked rice.
The remaining additions included "bizjet", a merging of the words "business" and "jet," "zomboid", which added another playable word ending in "-oid" and "beatdown."
"It means that in some ways the whole game is thrown open and made anew," Brewster said of the new additions. "I think it's especially exciting to people who play regularly."
