Many of the illustrated people, for the modernization of Spain, defended the implantation of education in other languages (French, English, Italian) in the centers, and the translation of outstanding works to Castilian. To the first were opposed those who defended the priority of the classic languages (Latin and Greek) as opposed to the modern ones, and to the second were opposed those who rejected the translations because they would introduce unnecessary foreign words in the Spanish language and would endanger its identity. Two positions arose thus: casticismo, that defended a pure language, without neither mixture of voices nor strange turns, with words documented by the authorities (the Royal Spanish Academy); and purismo, that was totally against the penetration of neologisms, mainly the foreign ones, blaming its opponents for being stainers of the language.
