In an on-line notice of a journal article, a language name that I don’t recall having come across before, but one I understood after a moment’s thought: Hexagonal French, the French spoken in the hexagon of France — that is, Metropolitan French, or more plainly, the French of France, France French, French French (occasionally referred to as European French or Continental French, but those terms would take in Belgian French and Swiss French, which are outside the hexagon). Meaning, of course, the standard, Paris-based, varieties of this language; there are plenty of provincial varieties in the country, plus other Romance languages related to French, and, even further afield, non-Romance languages within the hexagon, like the Celtic language Breton in Brittany.
From Wikipedia:
French of France is the predominant variety of the French language in France, Andorra and Monaco, in its formal and informal registers. It has, for a long time, been associated with Standard French. It is now seen as a variety of French alongside Acadian French [in the Maritimes], Belgian French, Quebec French, Swiss French, etc.
Lots to unpack here, starting with the hexagon. Which will lead immediately to names of regions, including those that constitute the land masses of political entities. including countries like France.
