How did Antonio de Nebrija’s Grammar of the Castilian Language support the standardization of Spanish?

Antonio de Nebrija’s Gramática Castellana (1492) supported the standardization of Spanish by providing a formal framework for the language, which he argued was necessary for creating an ennobled tongue suitable for imperial expansion.1

By codifying the rules of Castilian, Nebrija’s work helped elevate the language to a status capable of rivaling Latin for scholarly and literary purposes. This effort coincided with the completion of the Reconquista and the beginning of the Age of Discovery, positioning Castilian as a unified, prestigious tool for administration and influence as it was exported to the Americas. His grammar served as a foundational step in the transition toward a standardized national language, reflecting a broader movement in Romance languages to consciously fashion language as a precise instrument for thought and culture.12
