35 Spanish Irregular Verbs You’ll Actually Use

Spanish irregular verbs break away from the predictable endings of regular verbs, yet they appear in almost every sentence you’ll hear or speak!

While regular Spanish verbs simply swap their endings based on tense and person, irregular verbs change their stems, shift vowels, or take completely unique forms - and they make up over half of everyday Spanish verb usage.

Instead of overwhelming you with hundreds of conjugations, this guide focuses on 35 Spanish irregular verbs you’ll actually use in real life, from ser and tener to venir and oír.

How Spanish irregular verbs work

Regular verbs follow a straightforward conjugation pattern: take the infinitive verb, remove the ending (-ar, -er, -ir), and add predictable suffixes. For example, the Spanish verb hablar becomes hablo, hablas, habla, hablamos, hablaron. Most verb in Spanish follow this regular type of conjugation sequence.

Spanish irregular verbs don’t play by these rules though! They might change their stem (e.g. tener → tengo, tienes), use completely different forms across tenses (e.g. ir → voy in present, fui in preterite), or have unique spellings that catch learners off guard.

Here are the main irregular patterns you’re likely to encounter while learning Spanish:

• Stem changes: The vowel in the stem shifts (e→ie as in querer, o→ue as in poder, e→i as in seguir, u→ue as in jugar).

• Totally irregular verbs: Verbs like ser and ir that have irregular forms across multiple tenses.

• Irregular yo forms: Verbs that only change in the first person singular present (salir → salgo, conducir → conduzco).

This article focuses on present tense conjugations, with some common preterite tense forms that appear as especially irregular, such as fui, tuve, hice. The simple present tense is where you’ll likely use these verbs most, however.

35 Spanish Irregular Verbs

The six essential Spanish irregular verbs: ser, estar, haber, tener, ir, hacer

These six verbs form part of the backbone of Spanish grammar. You’ll use them to describe identity, states, existence, possession, movement, and actions - understand these first, and you’ll be able to handle real-world Spanish dialogue with confidence!

The verb ser describes identity and origin, while estar covers temporary states and locations. The auxiliary verb haber appears in perfect tenses and the common conjugation 'hay____________' ('there is/are__________'). Tener often refers to possessions, but also to age, as well as physical feelings, for example tengo hambre ('I’m hungry').

All six of these verbs are completely irregular in more than one tense. In the preterite tense, ser and ir share the same forms (fui, fuiste, fue), while tener becomes tuve and hacer becomes hice. These past tense forms are used frequently in everyday speech, so they’re worth memorising early alongside the present indicative!

Core daily actions - poder, decir, querer, venir, poner, salir, traer

These seven common irregular verbs describe everyday abilities, wants, communication, movement towards you, placing things, going out, and bringing items. You’ll use them when talking about work, social plans, and daily routines.

These verbs demonstrate several irregular patterns worth noting:

• Stem changes e→ie appear in querer (quiero, quieres, quiere) and venir (vengo, vienes, viene)

• The stem change o→ue appears in poder (puedo, puedes, puede)

• Irregular yo forms with -go endings: pongo, salgo, traigo, vengo, digo

Notice how many common verbs share the -go ending in the yo form. Once you spot this pattern, you’ll find it easier to predict how similar verbs are conjugated.

Talking about knowledge, perception and feelings - saber, conocer, ver, oír, sentir

This group covers how we know things, perceive the world, and express feelings. Understanding the difference between saber and conocer is essential to speaking Spanish fluently: saber refers to knowing facts or skills, while conocer refers to familiarity with people or places.

These verbs cover essential communication in the Spanish language. Note the irregular forms:

• Yo sé is the completely irregular first person of saber

• Yo veo drops the expected ending pattern

• Yo oigo adds an unexpected ‘g’

• Sentir has stem changes (siento, sientes, siente) following the e→ie pattern

The distinction between saber and conocer trips up many Spanish learners. Use saber for information (sé que tienes razón, 'I know you’re right') and skills (sé nadar, 'I know how to swim'). Use conocer for familiarity with people and places.

Movement and daily routines - volver, dormir, jugar, conducir, seguir, perder, empezar, dar

This group focuses on physical movement and common routines. Many are stem changing verbs in the present tense, which means their vowels shift when stressed.

Key stem changes in this group include:

• O→ue: dormir (duermo), volver (vuelvo)

• U→ue: The verb jugar is unique - it’s the only u→ue stem changer (juego)

• E→ie: empezar (empiezo), perder (pierdo)

• E→i: seguir (sigo, sigues, sigue)

• Irregular yo with -zco: conducir (conduzco)

These patterns repeat across other Spanish irregular verbs, so learning them here saves time with additional words that follow the same pattern.

Popular irregular yo verbs for real conversation - salir, despertarse, poner, encontrar, vestir, decir, suponer, traducir

Many high-frequency verbs are only truly irregular in the yo form of the present tense. The other tenses and persons often follow more regular patterns. Using these verbs correctly makes you sound natural when talking about yourself!

These spelling changes follow predictable mini-patterns:

• Verbs ending in -cir (like conducir, traducir) add -zco in the yo form

• Verbs like salir, poner, decir add -go

Once you recognise these patterns, you can predict the yo form of similar verbs.

Frequently asked questions about Spanish irregular verbs

How many irregular verbs are there in Spanish overall?

Spanish has over 250 irregular verbs in total, but a much smaller core of around 30 to 50 irregular verbs appear regularly in everyday speech. Frequency analyses show that while irregular verbs make up only about 10-12% of all Spanish verbs, they account for over 50% of verb usage in conversation!

Which irregular Spanish verbs should beginners learn first?

Start with the ten most common irregular Spanish verbs: ser, estar, tener, ir, hacer, poder, querer, decir, saber, and venir. These cover essential concepts like 'to be', 'to have', movement, basic actions, abilities, and wants. They appear in daily conversations about family, work, study, and free time. Study the present tense of these first, then add preterite forms (fui, tuve, hice, dije) once you’re comfortable.

Are irregular verbs used differently in Spain and Latin America?

The irregular verb forms themselves are largely the same across the Spanish-speaking world. The main difference lies in pronouns: Spain uses vosotros (vosotros vais, vosotros tenéis), while many countries in Latin America uses ustedes for both formal and informal plural “you.” Some Latin American countries, such as Argentina, also use vos instead of tú, which changes certain verb endings (e.g. querés instead of quieres). However, core conjugations like voy, tengo, quiero, and hice are understood everywhere.

How can I memorise Spanish irregular verbs more easily?

Here are four practical strategies that work:

• Group verbs by pattern: Learn all e→ie verbs together (querer, empezar, perder), then all -go verbs (pongo, salgo, traigo). Patterns stick better than random lists!

• Create personalised sentences: Write sentences about your actual life using each verb. Personal relevance boosts retention by around 25% overall.

• Use spaced-repetition flashcards: Revising verbs just as you’re about to forget them, which dramatically improves long-term memory.

• Work with a private Spanish tutor: Conversation practice encourages active recall and lets an expert correct your mistakes in real time.

Do I need to know all irregular verbs to pass an exam?

For most school exams (GCSE, A-level) and certificates (DELE A1–B1), exam boards publish specifications listing the key irregular verbs required. Past papers show that examiners repeatedly test the same high-frequency verbs: ser, estar, tener, ir, hacer, poder, querer, among others.
