Useful Grammar

In the present tense, certain verbs that terminate in -er also change the root of the stem, when stressed, from e to ie and from o to ue.

NOTE: Although undergoing the same changes in the present tense, these verbs are treated separately here from those of the first and second conjugations because, as will be studied shortly, these verbs also undergo additional changes in the past tense. As has been already studied, such verbs of the first and second conjugations remain regular in the past tense.

E — IE

sentir (to feel; to sense; to be sorry)

NOTE: Sentir used reflexively (sentirse) means to feel. Used non-reflexively, sentir means to sense or to be aware of, also to be sorry.

O — UE

dormir (to sleep)

NOTE: Dormir used reflexively (dormirse) means to fall asleep. Used non-reflexively, dormir means simply to sleep.
