First set of grammatical rules of the Spanish language
On this day in 1492, the first set of grammatical rules of the Spanish language was presented to Queen Isabella I of Castile.
Scholar, historian, poet, astronomer, and linguist Antonio de Nebrija realized that though Castellano was taught, there were no proper rules of grammar. He figured out what these were, and formalized them in the "Gramática de la lengua castellana".. When asked why such a book was necessary, de Nebrija defended the importance of a uniform language to honor the country's rich history, to hold a definitive place in writing, similarly to Greek and Latin, and to serve as the "instrument to the empire." This was the first of the European languages to have a dedicated grammar treatise.
