The RAE Dictionary is the ultimate reference for more than 500 million Spanish speakers worldwide. The new, thoroughly revised edition of the dictionary contains no fewer than 93,000 entries. In addition to removing highly localized or outdated terms, new concepts that are now widespread in our language, such as "precuela" and "pilates," have also been added. This edition offers 6,000 more terms than the 2001 edition. The RAE collaborated intensively with the twenty-two other American language institutes to present another pan-Hispanic work. The Real Academia Española, founded three hundred years ago, had the primary goal of compiling the Dictionary of Spanish Language. The first volume of the Autoridades Dictionary was published in 1726, and the first edition of the Dictionary of Spanish Language appeared in 1780.
