What does "irregular" mean?
With regular verbs you build every form from stem + ending: hablar → hablo, comer → como. With irregular verbs that doesn't work everywhere: tener doesn't become "teno", but tengo.
The good news: the endings almost always stay the same ones you already know. Usually only the stem changes - and often only in some forms. In the tables, the irregular part is printed in bold.
The stem changes: querer and poder
In querer, -e- becomes -ie-; in poder, -o- becomes -ue-. But not for nosotros and vosotros - there the stem stays as in the infinitiveinfinitiveThe basic form of a verb, e.g. hablar, comer or vivir.: queremos, podemos.
| querer | poder | |
|---|---|---|
| yo | quiero | puedo |
| tú | quieres | puedes |
| él/ella/usted | quiere | puede |
| nosotros/as | queremos | podemos |
| vosotros/as | queréis | podéis |
| ellos/ellas/ustedes | quieren | pueden |
The "I" form in -go: hacer, tener, venir
These three verbs have a -g- in the "I" form: hago, tengo, vengo. For hacer that is the only special feature. tener and venir also change their stem like querer (-e- → -ie-), but again not for nosotros and vosotros.
| hacer | tener | venir | |
|---|---|---|---|
| yo | hago | tengo | vengo |
| tú | haces | tienes | vienes |
| él/ella/usted | hace | tiene | viene |
| nosotros/as | hacemos | tenemos | venimos |
| vosotros/as | hacéis | tenéis | venís |
| ellos/ellas/ustedes | hacen | tienen | vienen |
ir - forms of its own
ir (to go) has no pattern you could work out. It's best to learn the forms by heart - they are short and very common: voy, vas, va, vamos, vais, van. Where you go is expressed with a: Voy a Madrid. Voy al supermercado. (a + el becomes al.)
querer and poder + infinitiveinfinitiveThe basic form of a verb, e.g. hablar, comer or vivir.
After querer and poder there is often a second verb in the infinitiveinfinitiveThe basic form of a verb, e.g. hablar, comer or vivir.. This is how you say what you want to do or can do: Quiero ir a España. (I want to go to Spain.) No puedo ir hoy. (I can't go today.) Only the first verb is conjugated.
