Diccionario crítico etimológico castellano e hispánico

The Diccionario crítico etimológico castellano e hispánico is a discursive etymological dictionary of Spanish compiled by Joan Coromines (also spelled Corominas) in collaboration with José Antonio Pascual.

The dictionary is an expansion and consolidation of earlier etymological publications by Corominas, particularly the mid-1950s Diccionario crítico etimológico de la lengua castellana.

"[2][3] Throughout more than six thousand pages, Corominas establishes the origin and development of Castilian vocabulary, both archaic and modern, Peninsular and Latin American, often referencing other Iberian and Romance languages.

The author supports his etymological judgments and dates of first documentation by citing earlier dictionaries and historical texts, showing in detail why he accepts or rejects previous scholarship.

The Seminari de Filologia i Informàtica at the Autonomous University of Barcelona began a project in 1992 to put the dictionary in digital form.
