The term Hispano-Gallican refers to the cultural and historical intersection of Spain and France, and there are a few synonyms that can be used to convey a similar meaning. The term "Franco-Spanish" is one such synonym, as it describes the same area of cultural overlap. Another synonym might be "Iberian-Gallican," which incorporates the broader concept of the Iberian Peninsula where Spain is located. Other synonyms could include "Occitano-Spanish" (referencing the Occitan language spoken in southern France), "Gallo-Hispanic," or "Hispanic-French." All of these synonyms serve to convey the idea of a blending or interchange of cultural influences between Spain and France.
