Quick Answer

All Spanish infinitives end in either -ar, -er, or -ir, as in hablar, leer, and escribir.

In this article we'll cover regular -er verbs, as well as some common -er verbs with irregular forms.

Regular -er Verbs

Many -er verbs follow the same conjugation pattern. To conjugate a regular -er verb, follow these steps:

  • First, decide your tense. Every tense in Spanish has a different set of endings.
  • Next, remove the infinitive ending (-er).
  • Lastly, add the ending that matches the subject of the sentence.

Irregular -er Verbs in the Present Tense

-er Stem Changers

Many common -er verbs have a stem change when conjugated in the present tense. These verbs use the same endings as regular -er verbs, but undergo a vowel change in the last syllable of the stem.

  • Present tense stem changes do not apply to nosotrosand vosotrosforms. These two forms maintain the form of the infinitive stem.

e > ie

For verbs in this group, the e in the last syllable of the stem changes to ie. Some common -er verbs that undergo this change are:

SpanishEnglish
atender
to look after
entender
to understand
perder
to lose
querer
to want
tener
to have

The yoform of tener is tengo. It does not have a stem change.

o > ue

For verbs in this group, the o in the last syllable of the stem changes to ue. Some common -er verbs that undergo this change are:

SpanishEnglish
doler
to hurt
llover
to rain
mover
to move
oler
to smell
poder
to be able to
volver
to return
