The Book Behind the Code

This exact number (9788467079975) identifies a massive milestone in Spanish lexicography: the Diccionario de sinónimos, antónimos y voces afines (Dictionary of Synonyms, Antonyms, and Related Words).

It is the very first official, comprehensive dictionary of synonyms and antonyms authored directly by the Real Academia Española (RAE) alongside the Association of Spanish Language Academies (ASALE). Because Espasa has a legendary history of acting as the official publishing partner for the RAE's major authoritative linguistic works—including their standard canonical dictionaries and reference bibles—the RAE handles the scholarly compiling while Espasa prints, distributes, and licenses the physical volumes under this exact 670 prefix.
