When the pattern breaks: Many of the most useful Spanish verbs are irregular in the present: they don't simply take the stem and add the regular ending. Their stem changes («poder» → puedo) or their yo form is special («tener» → tengo), but the rest of the endings are still the familiar present endings. Knowing the three big patterns — yo-go verbs, stem-changers and the fully irregular ser / ir — covers almost all of them.
- irregular
- irregular — the verb does not follow the plain stem + ending pattern
- el cambio de raíz
- the stem change — a vowel in the stem changes (e→ie, o→ue, e→i)
- el verbo de yo-go
- a yo-go verb — its «yo» form ends in -go (tengo, salgo, hago)
- la forma irregular
- the irregular form — a person that doesn't match the normal ending
- ser
- to be (identity, origin, characteristics) — fully irregular
- ir
- to go — fully irregular (voy, vas, va…)
Same jobs, trickier forms: Irregular verbs do the same jobs as regular ones — habits, facts, the here-and-now, near-future plans. Only the form is harder, so the marks live in getting the stem and the yo form right. Learn the high-frequency ones (tener, ir, ser, poder, querer, hacer) by heart.
Three patterns to know: Group the irregulars and they stop feeling random. Yo-go verbs are regular except for a -go in the «yo» form. Stem-changers swap a vowel in every person except nosotros / vosotros (the «boot» pattern). And ser / ir are fully irregular — just memorise them. The table below shows one verb per type.
| Tipo | Verbo | yo / tú / él | nosotros / vosotros / ellos |
|---|---|---|---|
| yo-go | tener | tengo · tienes · tiene | tenemos · tenéis · tienen |
| yo-go | poner | pongo · pones · pone | ponemos · ponéis · ponen |
| yo-go | salir | salgo · sales · sale | salimos · salís · salen |
| yo-go | hacer | hago · haces · hace | hacemos · hacéis · hacen |
| yo-go | decir | digo · dices · dice | decimos · decís · dicen |
| e→ie | querer | quiero · quieres · quiere | queremos · queréis · quieren |
| o→ue | poder | puedo · puedes · puede | podemos · podéis · pueden |
| e→i | pedir | pido · pides · pide | pedimos · pedís · piden |
| irregular | ser | soy · eres · es | somos · sois · son |
| irregular | ir | voy · vas · va | vamos · vais · van |
The «boot» and the yo-go: In a stem-changer, the vowel changes in yo, tú, él and ellos but stays normal in nosotros / vosotros — draw a line around the changed forms and it looks like a boot. Notice tener is both a yo-go (tengo) and a stem-changer (tienes, tiene, tienen). For ser and ir there's no shortcut: just learn the six forms.

Same jobs as the present: Irregular verbs do exactly the same jobs as regular present verbs — the form is the only difference. Here are the everyday uses, each shown with a high-frequency irregular verb.
Usos del presente (verbos irregulares)
- Habits & routines — «Cada día tengo clase de español.» (Every day I have a Spanish class.)
- General facts — «El museo es muy antiguo.» (The museum is very old.)
- Actions happening now — «Ahora voy al supermercado.» (I'm going to the supermarket now.)
- Near-future plans — «Esta noche salgo con mis amigos.» (Tonight I'm going out with my friends.)
- Wishes & ability — «Quiero viajar pero no puedo este año.» (I want to travel but I can't this year.)
Don't over-think the meaning: An irregular verb in the present means the same as a regular one: «tengo» is simply I have. The challenge is purely the form — get the stem change or the -go right and the rest works like any other present verb.
A day told with irregular verbs: Here's a short everyday paragraph built one sentence at a time. Each sentence packs in irregular present verbs — yo-go forms, stem-changers and ser / ir. Read it once for meaning, then tap Ver traducción for the English or 🔊 to hear it.

The slips to watch for: Two mistakes dominate: regularising a verb that should change its stem («podo» instead of puedo), and forgetting the yo-go («teno» instead of tengo). Compare the right version with the typical mistake and the fix becomes obvious.
Correcto
- Yo puedo ayudarte.
- Quiero un café, por favor.
- Yo tengo dos perros.
Error común
- Yo podo ayudarte.
- Quero un café, por favor.
- Yo teno dos perros.
Ask: does the stem change, and is there a yo-go?: Before you write a common verb, recall its pattern: poder, querer, pedir change their stem (puedo, quiero, pido); tener, poner, salir, hacer, decir add -go in the «yo» form (tengo, pongo, salgo, hago, digo). When in doubt, picture the boot.
