It's not the OED, but everyone's favorite Rachael Ray-ism is about to become an official part of our language, due for inclusion in the next edition of the Oxford American College Dictionary. The entry will read "EVOO: abbr. extra-virgin olive oil." The news was broken last week on Rachael Ray's talk show by the editor of the dictionary, who also spoke about how difficult it is to get words into the dictionary.
It makes you wonder if more people will buy the dictionary because of the new Rachael Ray connection, small though it is. It seems like the people buying the college edition of a dictionary are the most likely to turn to the internet (where you can easily find lots of info on EVOO) than to a reference book.
By the way - the cute shirt pictured here? It's available at the Rachael Ray shop.
