If you’re learning Spanish, you’ve already met the most common irregular verbs like ser, estar, and ir. But did you know there are dozens more? Irregular verbs are the key to moving beyond simple sentences and achieving real fluency. This page is your central guide to everything about Spanish irregular verbs, complete with on-demand conjugation charts and direct links to our specialized deep-dive pages and quizzes.
Unlike regular verbs, which follow predictable patterns, irregular verbs change their stem, ending, or both in various tenses. The good news is that many irregularities group into common types, making them much easier to learn.
Why You Can’t Ignore Irregular Verbs (And How to Conquer Them)
Irregular verbs are not rare exceptions; they are some of the most frequently used verbs in the Spanish language. You simply cannot speak Spanish without them. Instead of trying to memorize them all at once, we recommend a strategic approach:
- Focus on the Top 10 first.
- Learn them in context: Use them in sentences about your own life.
- Practice with patterns: Notice how verbs with similar irregularities often follow the same rules.
The “Big 3” – The Non-Negotiable Foundation
These are the most common and essential irregular verbs. You must know these inside and out.
- Ser (to be) – For permanent characteristics, identity, and time.
- Estar (to be) – For temporary states, locations, and emotions.
- Ir (to go) – For movement and forming the informal future tense.

Pro Tip: Verbs like tener, venir, poner, and salir often share similar irregular stems in the future and conditional tenses (e.g., tendr-, vendr-, pondr-, saldr-).
Tackle Present Tense Irregularities
Many verbs are only irregular in the present tense. The most common type is stem-changing verbs, often called “boot verbs.”
- Stem-changing e → ie: Pensar (to think), Empezar (to start), Entender (to understand), Preferir (to prefer)
- Stem-changing o → ue: Poder (to be able to), Dormir (to sleep), Volver (to return), Encontrar (to find)
- Stem-changing e → i: Pedir (to ask for), Servir (to serve), Seguir (to follow), Repetir (to repeat)
- Irregular “Yo” Form: Conocer (→ conozco), Dar (→ doy), Saber (→ sé)
Conquer Key Irregular Past Tense Verbs
The preterite (simple past) tense has its own set of common irregularities. These are crucial for telling stories about the past.

- Group 2: Hacer, Venir, Querer, Decir, Traer
