AR, ER, IR Verbs in Spanish: Endings for Every Tense

Quick answer: Every Spanish verb ends in -ar, -er or -ir in its infinitive form (hablar, comer, vivir). To conjugate a regular verb, drop the ending and add the ending for the person: hablar → hablo, hablas, habla… AR verbs use endings with a, while ER and IR verbs share almost the same endings with e and i.
Learn these three patterns and you can conjugate thousands of Spanish verbs. This guide has the AR, ER and IR verb charts for the present, preterite, imperfect and future tenses, lists of the most common regular verbs, and a quick quiz.
What are AR, ER and IR verbs?
Spanish verbs are grouped by the last two letters of the infinitive (the “to” form):
- -AR verbs (the largest group): hablar – to speak, trabajar – to work
- -ER verbs: comer – to eat, aprender – to learn
- -IR verbs: vivir – to live, escribir – to write
The part before the ending is the stem (habl-, com-, viv-). Regular verbs keep the stem and change only the ending.
Present tense: AR, ER, IR endings
| Pronoun | -AR (hablar) | -ER (comer) | -IR (vivir) |
|---|---|---|---|
| yo | hablo | como | vivo |
| tú | hablas | comes | vives |
| él / ella / usted | habla | come | vive |
| nosotros | hablamos | comemos | vivimos |
| vosotros | habláis | coméis | vivís |
| ellos / ustedes | hablan | comen | viven |
Tip: ER and IR verbs are identical in the present tense except for nosotros (-emos / -imos) and vosotros (-éis / -ís).
Preterite (simple past)
| Pronoun | -AR (hablar) | -ER (comer) | -IR (vivir) |
|---|---|---|---|
| yo | hablé | comí | viví |
| tú | hablaste | comiste | viviste |
| él / ella / usted | habló | comió | vivió |
| nosotros | hablamos | comimos | vivimos |
| vosotros | hablasteis | comisteis | vivisteis |
| ellos / ustedes | hablaron | comieron | vivieron |
In the preterite, ER and IR endings are exactly the same.
Imperfect (used to / was doing)
| Pronoun | -AR (hablar) | -ER (comer) | -IR (vivir) |
|---|---|---|---|
| yo | hablaba | comía | vivía |
| tú | hablabas | comías | vivías |
| él / ella / usted | hablaba | comía | vivía |
| nosotros | hablábamos | comíamos | vivíamos |
| vosotros | hablabais | comíais | vivíais |
| ellos / ustedes | hablaban | comían | vivían |
Future tense
The future is the easiest: keep the whole infinitive and add the same endings for all three groups: -é, -ás, -á, -emos, -éis, -án.
hablaré, comerás, vivirá, hablaremos, comeréis, vivirán
