Stem -Changing Verbs — O to UE (AR and ER Verbs)

Stem -Changing Verbs — O to UE (AR and ER Verbs)

contar (to count)

volver (to return)

(Note here again that no change takes place in the first person plural of these verbs because the accent does not fall upon the vowel of the stem but upon the first syllable of the ending.)

Other common verbs conjugated exactly like those above and changing the vowel of the stem from o to ue are as follows:

acordarse	(to remember)
acostarse	(to go to bed)
almorzar	(to eat lunch)
encontrar	(to find)
recordar	(to remember)
mover	(to move)

All vowel changing verbs of the first and second conjugations, studied above, go through no changes in the past tense. In the past tense they remain completely regular.
