Irregular present indicative and present subjunctive verb
forms
In the present indicative and subjunctive, irregularities in the stem of the
verb are not uncommon.
Radical changing verbs
In some cases there is a variation in the last vowel in a verb’s stem, e.g. recor-
damos‘we remember’ but recuerdo ‘I remember’. Verbs whose stem vowel
varies in this way are often called radical changing verbs, as the term ‘radi-
cal’ refers to the part of the stem that contains the vowel subject to variation.
The -ar and -er conjugations
Radical changing verbs in the -ar and -er conjugations undergo a change
in their final stem vowel in the present indicative and present subjunctive,
whenever the spoken stress falls on the stem rather than the ending.
