Irregular Verbs (Verbos Irregulares)

As in Spanish, the irregularities of the Asturian verbs may be classified in several types:

• Alternation of simple unstressed vowels with stressed diphthongs:

1. o : ue:

moyar : mueyo;
sorber : suerbo.
2. e : ie:

amestar : amiesto;
ferver : fiervo.
3. e : i:

correxir : corrixo.
4. e : ie : i:

sentir : siento : sintió.
5. o : ue : u:

dormir : duermo : durmió .
6. u : ue:

xugar : xuego.

• Alternation of unstressed diphthongs with stressed hyatuses (marked with a graphic accent):

• ai : aí:

entainar, entaíno
• au : aú:

aunir, aúno

• Irregularities in the endings:

• Verbs of the 2nd and 3rd conjugation with roots terminated in palatal c, y, s, l, n drop the [i] in the endings with [ie] and [io], cf.

fuxó, fuxeron;  coyó, coyere;  muñesti, muñendo
versus espardió, espardieron, espardiere, espardiesti, espardiendo.
• Verbs that (may)  drop the ending -e for the 3p. sg. of the Present Indicative, or the ending -i of the Imperative sg. This phenomenon occurs with verbs of the 2nd or 3rd conjugation the roots of which are terminated in vowel followed by l, n, r, s, z; cf.
(elli) muel, muel (tú);
(elli) pon, pon (tú);
(elli) quier; (elli) cues, cues (tú);
(elli) tex (or tex-e);
(elli) tarrez.
Compare with:
(elli) esparde, espardi (tú);
xime, ximi (tú);
(elli) cuerre, cuerri (tú);
(elli) finxe, finxi (tú);
(elli) france, franci (tú) etc...

• Combined Irregularities:

1. Verbs as

ser, tar, dicir, facer (faer), poner, andar, dir, haber, querer, tener, venir...
do have both particular root alternations and specific endings.
 
2. To this group are referred the verbs with irregular past participles too, such as:

ensugar, ensuchu;
romper, rotu;
escribir, escritu;
morrer, muertu...

• Alternations in Orthography (g : gu, c : qu, c : z):

regar : riegues;
emporcar : empuerques;
torcer : tuerzo.
