Orígenes de la "Ortografía" de la RAE primeras aportaciones de Bartolomé Alcázar (1715) y de Adrián Conink (h. 1716)

The "Discurso proemial de la orthographía de la Lengua Castellana"published in the Diccionario de Autoridades (1726) is the first orthography treatise of the Real Academia Espãola. The study of these documents which have not yet been studied allow us to increase our knowledge about the beginning of the normalization of modern Spanish orthography. The analysis of the lectures of BartoloméAlcázar ("Sobre si la Z es letra castellana", 1715) and Adrián Conink ("Discurso de la Orthographía de la lengua castellana", h. 1716) preserved in the ms. 112 of the Library of the Real Academia Espãola provides a better understanding of the first spelling rules of the Corporation. In this work, we consider not only the evolution of the spelling rules from its early formulations by Alcázar and by Conink until the final wording in the "Discurso proemial", but also the orthographic agreements collected in the Actas (1713-1739).
