> if you look at the data from neighboring countries. Which neighboring countries, exactly? Minority languages in Spain were suppressed for decades under the Franco government, and intermittently under assorted Spanish monarchies and republics before that. Germany had a diglossia between Hochdeutsch and assorted local tongues, and some of those local tongues still exist because the state saw them as legitimate regional dialects of the standard language. Italy never put nearly as much of a premium on suppressing the regional languages whose literature had contributed to Standard Italian, and those dialects have survived much better than e.g. Sardinian or Franco-Provencal.
