This event gave him a certain prestige in the field of Catalan linguistics. In 1911, he returned to Barcelona to become a professor (catedràtic) of Catalan — a position created by the diputació (local government) of Barcelona — and a member of the department of philology at the newly created Institut d'Estudis Catalans, of which he would later become president. In 1912 he published his Gramática de la lengua catalana (in Spanish).
