Sebastián de Covarrubias

During that time he lived with his uncle, Juan de Covarrubias, who was a canon of the Cathedral of Salamanca.

After Sebastián became a priest, the elder Covarrubias resigned his position in favor of his nephew.

Thereafter, Covarrubias became chaplain to Philip II of Spain, a consultant to the Congregation for the Doctrine of the Faith,[citation needed] and canon of the Cuenca Cathedral.

He is best known, however, for his etymological dictionary, Tesoro de la lengua castellana o española (Thesaurus of Castilian or Spanish Language), originally published in 1611.

[2] Though Covarrubias's supplement to the Tesoro was not published during his lifetime,[3] Spanish priest Benito Remigio Noydens produced a new edition in 1674.
