Remember that regular present tense -Ar, -Er and -Ir verbs are conjugated by removing the -ar, -er,or -ir infinitive endings and adding the correct endings for each conjugation:
| 1. Hablar | 2. Habl---->ar |
| 3. Habl- | 4. +one of the endings: o, as, a, amos, an |
| we end up with ----> | Hablo, Hablas, Habla, Hablamos, Hablan. |
But some verbs conjugate differently in the
Yo form. They don't simply add "o".
Dar
and Ver are among the irregular Yo form
verbs. Because they are three-letters long, we have to add
a bit more back to the Yo form:
| 1. Ver | 2. V---->er |
| 3. V- | 4. +one of the endings: o, es, e, emos, en |
| 5. we end up with ----> | *Vo, ves, ve, vemos, ven |
| 6. We have to add the "e" back in for "yo" : V + eo ----> | Veo |
| 1. Dar | 2. D---->ar |
| 3. D- | 4. + oy, es, e, emos, en |
| we end up with ----> | Doy, da, das, damos, dan |
| Subject Pronoun | Poner | Salir | Conocer |
| Yo | Pongo | Salgo | Conozco |
| Tú | Pones | Sales | Conoces |
| Él, ella, Usted | Pone | Sale | Conoce |
| Nosotros | Ponemos | Salimos | Conocemos |
| Ellos, ellas, Ustedes | Ponen | Salen | Conocen |
Saber (to know) has a unique irregular "yo" form, sé , but is regular in all the other forms of conjugation:
|
sé
|
sabes
|
sabe
|
sabemos
|
saben
|
Some verbs like Oír not only have an irregular Yo form but also have additional changes. The yo form is irregular, but so are the other forms. Notice the Nosotros form stays true to the infinitive form, carrying an accented "í".
| yo | tú | Él, ella, Usted | Nosotros | Ellos, ellas, Uds. | |
| Oír | oigo | oyes | oye | oímos | oyen |
