The "stemless" verb ir belongs to this group, with yendo. For -er and -ir verbs whose stem ends in ñ or ll , the -iendo ending is reduced to -endo: tañer → tañendo, bullir → bullendo. [4] The gerund has a variety of uses and can mean (with haciendo, for example) "doing/while doing/by doing/because of one's doing/through doing" and so on.
Vowel raising appears only in verbs of the third conjugation (-ir verbs), and in this group it affects dormir, morir, podrir (alternative of the more common pudrir) and nearly all verbs which have -e-as their last stem vowel (e.g. sentir, repetir); exceptions include cernir, discernir and concernir (all three diphthongizing, e-ie).

Conjugation is the variation in the endings of verbs (inflections) depending on the person (I, you, we, etc), tense (present, future, etc.) and mood (indicative, imperative, subjunctive, etc.). Most French verbs are regular and their inflections can be entirely determined by their infinitive form.
The table at the right shows the main verb forms, with examples for -ar, -er and -ir verbs (based on parlar 'to speak', vider 'to see', and audir 'to hear'). The simple past, future, and conditional tenses correspond to semantically identical compound tenses (composed of auxiliary verbs plus infinitives or past participles).
There are only three irregular verbs in the imperfect: ir, ser, and ver. Historically, ir — unlike other Spanish " -ir verbs" — failed to drop the -b- of the Latin imperfect. The imperfect of ser is likewise a continuation of the Latin imperfect (of esse ), with the same stem appearing in tú er es (thanks to pre-classical Latin rhotacism ).
