• Falling diphthong'': 'couto', 'souto', 'cantou', 'deitou', 'cantei'...'' • Anticipation of the "yod", like'': 'naide', 'coiro', 'agoiro', 'cadeira'...'' • No nasal diphthong at the end, as noted by Menéndez García as one of the benchmark isoglosses the speeches and Asturleonesas Galaicas.
Semivowels • Unlike Galician-Portuguese and Portuguese, Eonavian, like Galician, tends to the abolition of semiconsonants, but it has evolved its own way, linked to treatment of
nasality, such as the relative articles "condo", "contó" or the toponyms "Sayane" (Saint John) and the names "Xan" (John), "Xanón" (Big John), etc. • In Eonavian, as in the rest of the Galaicofonía, is a tendency to anticipatory assimilation, but today, both Eonavian and Galician have a strong influence from Castilian. In both cases, the process does not extend beyond the influence by it: 'naide', 'beizo', 'coiro', 'caldeiro', 'ribeira', etc.
Nasal consonants • Intervocalic vowels are lost. That fact is the argument of greater weight to those opposed to the theory of Astur-Galician, precisely because there is the curious fact that the phenomenon is accentuated in the municipalities close to the probable Eonaviegos West following a north-south trend is started in
Portugal. The fact is manifested in the formation of plurals, on increases in the training of women, but especially in the loss of the nasal-palatal. • The velarization of nasal vowels and deformation from n-falling. • The evolution of group Latin nn > n. • The retention of -mb-. • The group m'l and m'n changes to m • The loss of nasal-palatals, in diminutive feminine, vaquía, cousía, roupía, etc. and some masculines foucío, campío, en el sufijo -ieiro/a: cocieira, dieiro, mulieiro, etc. ===
Lateral consonants=== • The retention of intervocalic lateral consonants: except in the most western counties, the trend is the maintenance of intervocalic -l, except in the
cartulary of Villanueva de Oscos Monastery the tendency to the disappearance of the intervocalic -l- is like the rest of the Galician-Portuguese languages. • The palatalization of the initial lateral and degemination absence of Latin "-ll-". Now, it occurs in only half the territory, but the examination of the Cartulary de Oscos confirm that this phenomenon was widespread in all Galician and Asturian counties from the
River Eo and the
Navia River. • The velarization of "B'D" (cold, Dold, etc.), is now a very rare a phenomenon and absent from Huelves Acevedo García, who reported "coldo" and "codo", but it was widespread in the Oscos.
Evolution of the Latin groups • The evolution -cl-, -pl- and -fl- to palatal dull sound is agreed about in western Bable and Galician since "che vaqueira" tends to be more fricative (š) than affricate (ć). • The group -lt-, -ct- and -sc- evolved to it and ix. • The gj, gi, j, nj, li, gl were palatised. • The ss evolved to a palatal, dull fricative. • The gy, -dy-, -sc- evolved to a palatal dull fricative. • Liquid consonants after occlusives changed to vocalic sounds: oculu > òyo, vetulu > vèyo, apicula > abeya, tegula > tèya, flagrare > cheirar, agru > eiro, cathedra > cadèira.
Other phenomena • Fricative occlusives became sharper than Asturian, even more than in Galician: 'louxa', 'vixo', 'dexobado', 'xardía', 'broxa', 'xebrar', 'xastre', 'ameixola', 'èixola'. • Palatalization of
x. • Distinction between palatals, fricatives and laterals. García García proposes the following oppositions: 'callo' ('callar' verb), cayo ('caer' verb), rayo (meteorological phenomenon), rallo ('rallar' verb), etc. • Neutralization of liquid pool, but that phenomenon is on the verge of disappearance. • Retention of Latin -f-. • Geminate ss evolved to a fricative: Latin
passaru > Eonavian
páxaro, Latin
bassare > Eonavian
baxar, etc. == Morphology ==
