The irregular "yo" form
Many common Spanish verbs have a perfectly regular conjugation pattern, except for one rule-breaker: the yo (I) form.
For several of these verbs, the yo form ends in -go. For example, hacer (to do / to make) becomes hago (I do / I make).
| I am making dinner today. | Hoy hago la cena. |
For all other pronouns, hacer follows the normal -er verb rules.
| We make dinner late. | Hacemos la cena tarde. |
| What do you do on the weekend? | ¿Qué haces el fin de semana? |
Knowing things
The verb saber means "to know" when talking about facts, information, or how to do something. Its yo form is very short: sé (I know). Notice the accent mark!
| I do not know the answer. | No sé la respuesta. |
The rest of the forms are entirely regular.
| The teacher knows the answer. | El profesor sabe la respuesta. |
Going out and special pronouns
The verb salir (to go out / to leave) is another "-go" verb. Its yo form is salgo.
| I am going out to the street. | Salgo a la calle. |
When talking about doing things with someone, Spanish has special words for "with me" and "with you". Instead of combining con and mí, you use the single word conmigo. For "with you", use contigo.
| Do you want to go out with me on the weekend? | ¿Quieres salir conmigo el fin de semana? |
| I cannot go to the party with you. | No puedo ir a la fiesta contigo. |
Putting and seeing
Two more very common irregular yo verbs are poner (to put) and ver (to see).
- poner becomes pongo
- ver becomes veo
| I put the book on the table. | Pongo el libro en la mesa. |
| I do not see the car. | No veo el coche. |
