Street slang including thang, innit and grrl along with words from the internet such as Wiki and MySpace have been added to an "official" reference for Scrabble players.
The Collins Official Scrabble Words also now includes, from Indian cookery, keema, alu, or aloo, and gobi amongst nearly 3,000 new additions to those allowed in the game.
Others permitted include words for various kinds of drugs such as tik, gak and tina.
The list for the latest edition of the book was created by staff at Collins Dictionaries based in Glasgow.
The publishers say it is the "most comprehensive Scrabble wordlist ever produced".
Robert Groves, editor of Collins English Dictionaries and editor of the latest wordlist for Scrabble users, said: "The latest edition adds nearly 3,000 new words to the existing quarter of a million available to Scrabble players.
"These additions are an eclectic mix of new technological jargon, overseas English, recent colloquialisms, street slang and a few fairly well-established phrases that had not made it on to the list until now.
"It is the essential reference for all Scrabble players, from tournament enthusiasts to families battling it out in their front rooms.
"Over half of British homes own a Scrabble board, over four million games are sold worldwide each year, and nearly anyone who has played it has been involved in a dispute over which words can and can't be used. Now all those arguments can be settled, with the latest official wordlist from Collins - the authority on Scrabble.
"While compiling this list we looked at dictionaries dating back to 2006. The wordlist was also compiled using the Collins Corpus - the world's largest language database of written and spoken English."
