Eonavian or Galician-Asturian, (official name by Act 1/1998, March 23 of Principality of Asturias) ( autonym: eonaviego, gallego-asturiano; ; ) is a term used to refer to a set of Romance dialects or falas whose linguistic dominion extends into the zone of Asturias between the Eo River and Navia River (or more specifically the Eo and the Frejulfe River). The dialects have been variously classified as the northeastern varieties of Galician, as a linguistic group of its own, or as a Galician dialect of transition to the Astur-Leonese group.
The area where the dialects are spoken includes the Asturian municipalities of Boal, Castropol, Coaña, Eilao, El Franco, Grandas de Salime, Pezós, San Martín de Ozcos, Santalla de Ozcos, Santiso de Abres, Tapia de Casariego, Taramundi, A Veiga, Vilanova de Ozcos, and partially those of Navia, Ibias, Villayón, and Allande.
Other terms used include gallego-asturiano, the official term in Asturias, meaning "Galician-Asturian language", a fala ("the speech", not to be confused with the Fala language of Extremadura) and Galego de Asturias ("Galician language of Asturias"). The term Eonaviego was first used by the linguist Xavier Frías Conde, who translated it as Eonavian in English, Éonavien in French, and Eonavienc in Catalan. In 2007, the Academy of the Asturian Language accepted the term of Eonavian to refer to the Galician-Portuguese dialect.
The set of dialects was traditionally included by linguists as Galician-Portuguese or Galician, with some characteristics of the Astur-Leonese Group. That was the opinion of such linguists as Menéndez Pidal, Eugenio Coseriu, Luís Lindley Cintra, Dámaso Alonso, and more recent ones such as Francisco Xavier Frías Conde and Xoán Babarro. Now, however, there is a political-linguistic conflict on the identity of the language between those who prioritise the mixed identity and those that continue to prioritise the Galician substratum. Supporters of the former, mostly in Asturias, identify Eonavian as a dialect continuum between the Asturian and Galician languages or even a third language belonging to Portuguese-Galician group spoken only in that area (Ruth González Rodríguez, Ricardo Saavedra Fernández-Combarro and Xoxé Miguel Suárez). Supporters of the latter, mostly in Galicia, identify it as Galician and want the same protection as Galician in Castile and Leon, which protects the dialects of El Bierzo in cooperation with the Galician government.
