From a fairly young age Fabra dedicated himself to the study of the Catalan language.[1] Through the journal and publishing house Tipografia de L'Avenç [Wikidata], he participated in a campaign to reform Catalan orthography between 1890–92. He published Tractat d'ortografia catalana with the writer and publisher Jaume Massó i Torrents [Wikidata] and Joaquim Casas i Carbó [Wikidata], a notable lawyer and writer, in 1904.
