The Royal Spanish Academy (Real Academia Española, RAE) is the Spanish official institution responsible for overseeing the Spanish language since 1713. The RAE is affiliated with national language academies in twenty-two other Spanish-speaking nations through the Association of Spanish Language Academies (Asociación de Academias de la Lengua Española, ASALE). The RAE and ASALE promote a pan-hispanic linguistic unity and integrity within and among their respective territories to ensure a common language standard while acknowledging polycentric koinés. To achieve this goal, RAE regularly publishes dictionaries, grammars, orthographies and classical literary works. Free linguistic advice is also provided. The RAE has been recently advising in the Spanish National Plan for the Advancement of Language Technology.
