Definition of Regular and Irregular Verbs
In Spanish, verbs are categorized as either regular or irregular based on how they behave when conjugated. The conjugation of a verb involves altering its ending to reflect tense, mood, person, and number.
Understanding this distinction is fundamental to mastering Spanish verb conjugation.
Regular verbs follow predictable patterns when conjugated. Their stem (the part of the verb that remains after removing the infinitive ending -AR, -ER, or -IR) stays consistent, and their endings conform to standard conjugation rules for each tense. These verbs are the building blocks of Spanish grammar and are generally easier to learn.
Irregular verbs, on the other hand, deviate from these standard patterns. They may have stem changes, irregular yo forms, or other unpredictable alterations in their conjugation. These verbs require more memorization and careful attention to detail. Irregular verbs are common and essential, making their mastery crucial for fluency.
The classification of verbs as regular or irregular directly impacts how they are conjugated in different tenses and moods. Recognizing whether a verb is regular or irregular is the first step in correctly conjugating it.
This knowledge enables learners to apply the appropriate conjugation rules or to identify and memorize the irregular forms.
Regular Verbs in Spanish
Regular verbs in Spanish are those that follow a consistent pattern of conjugation across all tenses and moods. They are categorized into three groups based on their infinitive endings: -AR, -ER, and -IR.
Regular -AR Verbs
-AR verbs are the most common type of verb in Spanish. To conjugate a regular -AR verb in the present tense, you remove the -AR ending from the infinitive and add the appropriate ending for each pronoun.
The stem remains unchanged throughout the conjugation.
Here’s a table illustrating the present tense conjugation of the regular -AR verb hablar (to speak):
| Pronoun | Ending | Hablar (to speak) |
|---|---|---|
| Yo (I) | -o | Hablo |
| Tú (You, informal) | -as | Hablas |
| Él/Ella/Usted (He/She/You, formal) | -a | Habla |
| Nosotros/Nosotras (We) | -amos | Hablamos |
| Vosotros/Vosotras (You, informal plural) | -áis | Habláis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | -an | Hablan |
As you can see, the stem “habl-” remains constant, and the endings change according to the pronoun. This consistency is characteristic of regular -AR verbs.
Here are more examples of regular -AR verbs conjugated in the present tense:
| Verb | Yo | Tú | Él/Ella/Usted | Nosotros/Nosotras | Vosotros/Vosotras | Ellos/Ellas/Ustedes |
|---|---|---|---|---|---|---|
| Cantar (to sing) | Canto | Cantas | Canta | Cantamos | Cantáis | Cantan |
| Bailar (to dance) | Bailo | Bailas | Baila | Bailamos | Bailáis | Bailan |
| Estudiar (to study) | Estudio | Estudias | Estudia | Estudiamos | Estudiáis | Estudian |
| Trabajar (to work) | Trabajo | Trabajas | Trabaja | Trabajamos | Trabajáis | Trabajan |
| Comprar (to buy) | Compro | Compras | Compra | Compramos | Compráis | Compran |
| Cocinar (to cook) | Cocino | Cocinas | Cocina | Cocinamos | Cocináis | Cocinan |
| Viajar (to travel) | Viajo | Viajas | Viaja | Viajamos | Viajáis | Viajan |
| Nadar (to swim) | Nado | Nadas | Nada | Nadamos | Nadáis | Nadan |
| Llamar (to call) | Llamo | Llamas | Llama | Llamamos | Llamáis | Llaman |
| Esperar (to wait) | Espero | Esperas | Espera | Esperamos | Esperáis | Esperan |
| Entrar (to enter) | Entro | Entras | Entra | Entramos | Entráis | Entran |
| Necesitar (to need) | Necesito | Necesitas | Necesita | Necesitamos | Necesitáis | Necesitan |
| Preguntar (to ask) | Pregunto | Preguntas | Pregunta | Preguntamos | Preguntáis | Preguntan |
| Tomar (to take) | Tomo | Tomas | Toma | Tomamos | Tomáis | Toman |
| Visitar (to visit) | Visito | Visitas | Visita | Visitamos | Visitáis | Visitan |
| Ayudar (to help) | Ayudo | Ayudas | Ayuda | Ayudamos | Ayudáis | Ayudan |
| Buscar (to search) | Busco | Buscas | Busca | Buscamos | Buscáis | Buscan |
| Caminar (to walk) | Camino | Caminas | Camina | Caminamos | Camináis | Caminan |
| Dejar (to leave) | Dejo | Dejas | Deja | Dejamos | Dejáis | Dejan |
| Encontrar (to find) | Encuentro | Encuentras | Encuentra | Encontramos | Encontráis | Encuentran |
The pattern remains consistent: remove the -AR ending and add the appropriate ending for each pronoun. This predictability makes regular -AR verbs relatively straightforward to learn.
Regular -ER Verbs
Regular -ER verbs follow a similar pattern to -AR verbs. To conjugate them in the present tense, you remove the -ER ending and add the corresponding endings for each pronoun.
Again, the stem remains consistent throughout the conjugation.
Here’s the present tense conjugation of the regular -ER verb comer (to eat):
| Pronoun | Ending | Comer (to eat) |
|---|---|---|
| Yo (I) | -o | Como |
| Tú (You, informal) | -es | Comes |
| Él/Ella/Usted (He/She/You, formal) | -e | Come |
| Nosotros/Nosotras (We) | -emos | Comemos |
| Vosotros/Vosotras (You, informal plural) | -éis | Coméis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | -en | Comen |
Note that the stem “com-” remains constant, and the endings change according to the pronoun. This is the hallmark of a regular -ER verb.
Here are additional examples of regular -ER verbs conjugated in the present tense:
| Verb | Yo | Tú | Él/Ella/Usted | Nosotros/Nosotras | Vosotros/Vosotras | Ellos/Ellas/Ustedes |
|---|---|---|---|---|---|---|
| Beber (to drink) | Bebo | Bebes | Bebe | Bebemos | Bebéis | Beben |
| Leer (to read) | Leo | Lees | Lee | Leemos | Leéis | Leen |
| Aprender (to learn) | Aprendo | Aprendes | Aprende | Aprendemos | Aprendéis | Aprenden |
| Vender (to sell) | Vendo | Vendes | Vende | Vendemos | Vendéis | Venden |
| Creer (to believe) | Creo | Crees | Cree | Creemos | Creéis | Creen |
| Deber (should/must) | Debo | Debes | Debe | Debemos | Debéis | Deben |
| Prometer (to promise) | Prometo | Prometes | Promete | Prometemos | Prometéis | Prometen |
| Temer (to fear) | Temo | Temes | Teme | Tememos | Teméis | Temen |
| Comprender (to understand) | Comprendo | Comprendes | Comprende | Comprendemos | Comprendéis | Comprenden |
| Esconder (to hide) | Escondo | Escondes | Esconde | Escondemos | Escondéis | Esconden |
| Meter (to put) | Meto | Metes | Mete | Metemos | Metéis | Meten |
| Romper (to break) | Rompo | Rompes | Rompe | Rompemos | Rompéis | Rompen |
| Correr (to run) | Corro | Corres | Corre | Corremos | Corréis | Corren |
| Resolver (to resolve) | Resuelvo | Resuelves | Resuelve | Resolvemos | Resolvéis | Resuelven |
| Ofender (to offend) | Ofendo | Ofendes | Ofende | Ofendemos | Ofendéis | Ofenden |
| Poseer (to possess) | Poseo | Posees | Posee | Poseemos | Poseéis | Poseen |
| Proteger (to protect) | Protejo | Proteges | Protege | Protegemos | Protegéis | Protegen |
| Responder (to answer) | Respondo | Respondes | Responde | Respondemos | Respondéis | Responden |
| Suponer (to suppose) | Supongo | Supones | Supone | Suponemos | Suponéis | Suponen |
| Torcer (to twist) | Torzco | Tuerces | Tuerce | Torcemos | Torcéis | Tuercen |
The consistency in stem and endings makes regular -ER verbs manageable to learn and use.
Regular -IR Verbs
Regular -IR verbs also follow a predictable pattern. To conjugate them in the present tense, remove the -IR ending and add the appropriate endings.
The stem remains consistent, similar to -AR and -ER verbs.
Here’s the present tense conjugation of the regular -IR verb vivir (to live):
| Pronoun | Ending | Vivir (to live) |
|---|---|---|
| Yo (I) | -o | Vivo |
| Tú (You, informal) | -es | Vives |
| Él/Ella/Usted (He/She/You, formal) | -e | Vive |
| Nosotros/Nosotras (We) | -imos | Vivimos |
| Vosotros/Vosotras (You, informal plural) | -ís | Vivís |
| Ellos/Ellas/Ustedes (They/You, formal plural) | -en | Viven |
Notice the consistent stem “viv-” and the predictable endings. This is characteristic of regular -IR verbs.
Here are more examples of regular -IR verbs conjugated in the present tense:
| Verb | Yo | Tú | Él/Ella/Usted | Nosotros/Nosotras | Vosotros/Vosotras | Ellos/Ellas/Ustedes |
|---|---|---|---|---|---|---|
| Escribir (to write) | Escribo | Escribes | Escribe | Escribimos | Escribís | Escriben |

| Unir (to unite) | Uno | Unes | Une | Unimos | Unís | Unen |
Regular -IR verbs are consistent in their stem and endings, making them predictable and easier to learn.
Irregular Verbs in Spanish
Irregular verbs in Spanish do not follow the standard conjugation patterns of regular verbs. They require memorization of specific forms and patterns.
Irregularities can manifest in several ways, including stem changes, irregular yo forms, and radical irregularities.
Stem-Changing Verbs
Stem-changing verbs alter the stem vowel in certain conjugations, typically in the present tense. These changes usually occur in all forms except nosotros and vosotros.
E to IE Stem-Changing Verbs
In E to IE stem-changing verbs, the ‘e’ in the stem changes to ‘ie’ when stressed. This occurs in all forms except nosotros and vosotros.
Here’s the present tense conjugation of pensar (to think), an E to IE stem-changing verb:
| Pronoun | Pensar (to think) |
|---|---|
| Yo (I) | Pienso |
| Tú (You, informal) | Piensas |
| Él/Ella/Usted (He/She/You, formal) | Piensa |
| Nosotros/Nosotras (We) | Pensamos |
| Vosotros/Vosotras (You, informal plural) | Pensáis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Piensan |
Notice how the ‘e’ in ‘pens-‘ changes to ‘ie’ in all forms except nosotros and vosotros.
Examples of other E to IE stem-changing verbs include:
- Empezar (to begin)
- Querer (to want)
- Preferir (to prefer)
- Cerrar (to close)
- Entender (to understand)
O to UE Stem-Changing Verbs
In O to UE stem-changing verbs, the ‘o’ in the stem changes to ‘ue’ when stressed, again excluding the nosotros and vosotros forms.
Here’s the present tense conjugation of poder (to be able to), an O to UE stem-changing verb:
| Pronoun | Poder (to be able to) |
|---|---|
| Yo (I) | Puedo |
| Tú (You, informal) | Puedes |
| Él/Ella/Usted (He/She/You, formal) | Puede |
| Nosotros/Nosotras (We) | Podemos |
| Vosotros/Vosotras (You, informal plural) | Podéis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Pueden |
The ‘o’ in ‘pod-‘ changes to ‘ue’ in all forms except nosotros and vosotros.
Examples of other O to UE stem-changing verbs include:
- Contar (to count/tell)
- Dormir (to sleep)
- Volver (to return)
- Almorzar (to have lunch)
- Encontrar (to find)
E to I Stem-Changing Verbs
In E to I stem-changing verbs, the ‘e’ in the stem changes to ‘i’ when stressed. This change occurs in all forms except nosotros and vosotros. This stem change often occurs in -IR verbs.
Here’s the present tense conjugation of pedir (to ask for), an E to I stem-changing verb:
| Pronoun | Pedir (to ask for) |
|---|---|
| Yo (I) | Pido |
| Tú (You, informal) | Pides |
| Él/Ella/Usted (He/She/You, formal) | Pide |
| Nosotros/Nosotras (We) | Pedimos |
| Vosotros/Vosotras (You, informal plural) | Pedís |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Piden |
The ‘e’ in ‘ped-‘ changes to ‘i’ in all forms except nosotros and vosotros.
Examples of other E to I stem-changing verbs include:
- Servir (to serve)
- Repetir (to repeat)
- Seguir (to follow)
- Vestir (to dress)
- Competir (to compete)
U to UE Stem-Changing Verbs
There is only one common U to UE stem-changing verb: jugar (to play). The ‘u’ in the stem changes to ‘ue’ when stressed, excluding the nosotros and vosotros forms.
Here’s the present tense conjugation of jugar (to play):
| Pronoun | Jugar (to play) |
|---|---|
| Yo (I) | Juego |
| Tú (You, informal) | Juegas |
| Él/Ella/Usted (He/She/You, formal) | Juega |
| Nosotros/Nosotras (We) | Jugamos |
| Vosotros/Vosotras (You, informal plural) | Jugáis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Juegan |
The ‘u’ in ‘jug-‘ changes to ‘ue’ in all forms except nosotros and vosotros.
Irregular Yo Form Verbs
Some verbs have an irregular form only in the yo (I) form of the present tense. The other forms follow regular patterns.
Examples include:
- Hacer (to do/make) – Yo hago
- Poner (to put) – Yo pongo
- Saber (to know) – Yo sé
- Salir (to leave) – Yo salgo
- Traer (to bring) – Yo traigo
- Ver (to see) – Yo veo
- Oír (to hear) – Yo oigo
- Conocer (to know) – Yo conozco
- Dar (to give) – Yo doy
For example, the present tense conjugation of hacer (to do/make) is:
| Pronoun | Hacer (to do/make) |
|---|---|
| Yo (I) | Hago |
| Tú (You, informal) | Haces |
| Él/Ella/Usted (He/She/You, formal) | Hace |
| Nosotros/Nosotras (We) | Hacemos |
| Vosotros/Vosotras (You, informal plural) | Hacéis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Hacen |
Only the yo form is irregular; the rest follow the regular -ER verb pattern.
Radically Irregular Verbs
Radically irregular verbs have significant deviations from the standard conjugation patterns across multiple forms and tenses. These verbs often have completely different stems or endings compared to regular verbs.
These are some of the most challenging verbs to learn.
Some of the most common radically irregular verbs include:
- Ser (to be)
- Ir (to go)
- Estar (to be)
- Tener (to have)
- Venir (to come)
- Decir (to say/tell)
<
For example, the present tense conjugation of ser (to be) is:
| Pronoun | Ser (to be) |
|---|---|
| Yo (I) | Soy |
| Tú (You, informal) | Eres |
| Él/Ella/Usted (He/She/You, formal) | Es |
| Nosotros/Nosotras (We) | Somos |
| Vosotros/Vosotras (You, informal plural) | Sois |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Son |
As you can see, all forms are irregular, bearing little resemblance to a regular verb conjugation.
