Irregular “yo” verbs: hago, pongo, salgo…
Some everyday verbs are irregular only in the yo form. Everything else follows the normal pattern.
Theory
Learn the yo form by heart; the other five forms are regular.

| Verb | yo | tú (regular) |
|---|---|---|
| hacer | hago | haces |
| poner | pongo | pones |
| salir | salgo | sales |
| traer | traigo | traes |
| ver | veo | ves |
| dar | doy | das |

-go + a stem change
| Verb | yo | tú |
