There exists priority translation pairs, from the standpoint of endangered languages. Such notion of a priority pair (the most useful pair for the current users of the endangered language), regarding a given endangered language. For example, French to Corsican is a priority pair, with respect to other pairs suchas Gallurese-Corsican, English-Corsican or Spanish-Corsican. In this context, any endangered language has its own priority pair. For example, a priority pair for sardinian gallurese is Italian-Gallurese. In the same way, a priority pair for sardinian sassarese is Italian-Sassarese. In an analogous way, a priority pair for sicilian language is Italian-Sicilian.
