Toponyms like Ourense, A Coruña, Fisterra became Orense, La Coruña, Finisterre. In many cases this linguistic assimilation created confusion, for example Niño da Aguia (Galician: Eagle's Nest) was translated into Spanish as Niño de la Guía (Spanish: the Guide's child) and Mesón do Bento (Galician: Benedict's house) was translated as Mesón del Viento (Spanish: House of Wind).
The linguistic shift from Galician to Spanish resulted in misinterpretations, such as translating "Niño da Aguia" (Eagle's Nest) into "Niño de la Guía" (the Guide's child), and "Mesón do Bento" (Benedict's house) into "Mesón del Viento" (House of Wind).
