“El nombre latino y el origen de la ciudad de Morón”, Desde la Frontera. Revista de Temas Moronenses, 6 (1993), 1-24.

I prove that the Andalusian place name Moron, former Mauror (Mawrûr) in the Arabic texts, comes from Late Latin maurorum, 'of the Moors'. This and other evidences suggest that the population originatedd in the sixth century A.D. I also deal with the place name Arunci, now Aroche in the province of Huelva, and with a word morón that never meant hillock in Spanish.
