Antonio de Nebrija wrote the Gramática de la lengua castellana in 1492, the first published grammar study of any modern European language. He also produced the first dictionary of Spanish, the Vocabulario español-latino, around 1495.
Nebrija was born in 1444 in a town in the province of Seville then called Nebrixa, now known as Lebrija. He was the second of five children in a hidalgo family; his parents were Juan Martínez de Cala and Catalina de Xarana.
Nebrija dedicated the 1492 Gramática de la lengua castellana to Isabella I and argued in the dedication that language was "the instrument of empire." He suggested the grammar would be useful as the Catholic monarchs governed peoples who spoke languages other than Castilian.
Around 1504, Grand Inquisitor Diego de Deza confiscated and destroyed Nebrija's biblical scholarship. After Cardinal Jiménez de Cisneros succeeded Deza in 1507, Nebrija was allowed to resume his work, but his contributions to the Complutensian Polyglot Bible were largely ignored when it was published in 1517.
Nebrija's Vocabulario español-latino of around 1495 served as the basis for translating dictionaries into other languages. Authors used it to build Spanish-Arabic (1505), Spanish-Nahuatl (1547), and Spanish-Tagalog (1613) dictionaries.
Nebrija died on the 5th of July 1522 in Alcalá de Henares, Spain. He was born in 1444, making him approximately 78 years old at his death.
