Definition of Regular and Irregular Verbs
In Spanish, verbs are the backbone of sentences, indicating actions, states, and occurrences. Understanding the difference between regular and irregular verbs is fundamental to mastering Spanish conjugation and constructing grammatically correct sentences. The classification hinges on how verbs change their forms to indicate tense, mood, and person.
Regular Verbs
Regular verbs in Spanish are those that follow predictable conjugation patterns in all tenses. Their stem (the part of the verb before the -ar, -er, or -ir ending) remains consistent, and their endings adhere to a standard set of rules. These verbs are easier to learn because once you understand the pattern for one regular verb, you can apply it to many others.
For example, the regular -ar verb hablar (to speak) always follows the same conjugation pattern in the present tense: yo hablo, tú hablas, él/ella/usted habla, nosotros hablamos, vosotros habláis, ellos/ellas/ustedes hablan. Similarly, the regular -er verb comer (to eat) and the regular -ir verb vivir (to live) have their own consistent patterns.
Irregular Verbs
Irregular verbs, conversely, deviate from the standard conjugation patterns. They may have stem changes, irregular yo forms, or completely unpredictable forms in certain tenses. These verbs require more memorization and practice because their conjugations do not follow a single, consistent rule. Recognizing and learning these irregularities is crucial for accurate and fluent Spanish communication.
For example, the verb tener (to have) is an irregular verb because it undergoes stem changes in the present tense (yo tengo, tú tienes, él/ella/usted tiene, etc.). Similarly, the verb ir (to go) is completely irregular, with unique forms that don’t adhere to any standard pattern (yo voy, tú vas, él/ella/usted va, etc.).
Structural Breakdown
To understand how regular and irregular verbs differ, it’s important to break down their structural components and conjugation patterns. Spanish verbs are classified into three groups based on their infinitive endings: -ar, -er, and -ir. Each group has its own set of regular conjugation patterns, but irregular verbs deviate from these patterns in various ways.
Verb Endings (-ar, -er, -ir)
The infinitive ending of a verb indicates its group. Identifying this ending is the first step in conjugating the verb. The next step involves removing the infinitive ending to reveal the verb’s stem. The stem is the foundation upon which conjugations are built.
For example:
- Hablar (-ar verb): Stem is habl-
- Comer (-er verb): Stem is com-
- Vivir (-ir verb): Stem is viv-
Conjugation Patterns
Regular verbs follow specific conjugation patterns based on their infinitive ending. These patterns dictate how the verb changes in different tenses and for different subjects. Understanding these patterns is essential for conjugating regular verbs correctly.
Here’s a brief overview of the present tense conjugation patterns for regular verbs:
| Pronoun | -ar Ending | -er Ending | -ir Ending |
|---|---|---|---|
| Yo (I) | -o | -o | -o |
| Tú (You, informal) | -as | -es | -es |
| Él/Ella/Usted (He/She/You, formal) | -a | -e | -e |
| Nosotros (We) | -amos | -emos | -imos |
| Vosotros (You, informal plural – Spain) | -áis | -éis | -ís |
| Ellos/Ellas/Ustedes (They/You, formal plural) | -an | -en | -en |
These patterns serve as the foundation for conjugating regular verbs. By memorizing these endings, you can accurately conjugate a wide range of regular verbs in the present tense. However, irregular verbs deviate from these patterns, requiring individual attention and memorization.
Types of Irregularities
Irregular verbs in Spanish exhibit several types of irregularities. These irregularities can affect the stem, the endings, or both. Understanding these different types of irregularities is crucial for mastering irregular verb conjugations.
Stem-Changing Verbs
Stem-changing verbs are those in which the vowel in the stem changes in certain conjugations. These changes typically occur in the present tense and sometimes in the preterite tense. There are several types of stem changes, including:
- e → ie: Verbs like pensar (to think) change their stem from pens- to piens- in most forms (yo pienso, tú piensas, él/ella/usted piensa, ellos/ellas/ustedes piensan). The nosotros and vosotros forms remain regular (nosotros pensamos, vosotros pensáis).
- o → ue: Verbs like poder (to be able to) change their stem from pod- to pued- in most forms (yo puedo, tú puedes, él/ella/usted puede, ellos/ellas/ustedes pueden). The nosotros and vosotros forms remain regular (nosotros podemos, vosotros podéis).
- e → i: Verbs like pedir (to ask for) change their stem from ped- to pid- in the third person singular and plural in the preterite tense (él/ella/usted pidió, ellos/ellas/ustedes pidieron). In the present tense, this change occurs in all forms except nosotros and vosotros (yo pido, tú pides, él/ella/usted pide, ellos/ellas/ustedes piden).
- u → ue: The verb jugar (to play) is the most common verb that follows this pattern. (yo juego, tú juegas, él/ella/usted juega, ellos/ellas/ustedes juegan). The nosotros and vosotros forms remain regular (nosotros jugamos, vosotros jugáis).
Orthographic-Changing Verbs
Orthographic-changing verbs are those that undergo spelling changes to maintain pronunciation. These changes usually occur when the stem ends in a consonant that affects the pronunciation of the following vowel. Common orthographic changes include:
- c → qu: Verbs like tocar (to touch) change the c to qu before the -e ending in the present subjunctive (yo toque).
- g → gu: Verbs like llegar (to arrive) change the g to gu before the -e ending in the present subjunctive (yo llegue).
- z → c: Verbs like empezar (to begin) change the z to c before the -e ending in the present subjunctive (yo empiece).
- gu → gü: Verbs like averiguar (to investigate) add a dieresis over the u before the -e ending in the present subjunctive (yo averigüe).
Irregular Yo Form Verbs
Some verbs have an irregular form only in the yo (I) form of the present tense. The remaining forms follow regular conjugation patterns. Common verbs with irregular yo forms include:
- Hacer (to do/make): yo hago
- Poner (to put/place): yo pongo
- Salir (to leave/go out): yo salgo
- Traer (to bring): yo traigo
- Saber (to know): yo sé
- Ver (to see): yo veo
- Dar (to give): yo doy
Completely Irregular Verbs
Completely irregular verbs have unpredictable forms that don’t adhere to any standard patterns. These verbs require memorization of all their forms. Some of the most common completely irregular verbs include:
- Ser (to be): yo soy, tú eres, él/ella/usted es, nosotros somos, vosotros sois, ellos/ellas/ustedes son
- Ir (to go): yo voy, tú vas, él/ella/usted va, nosotros vamos, vosotros vais, ellos/ellas/ustedes van
- Estar (to be): yo estoy, tú estás, él/ella/usted está, nosotros estamos, vosotros estáis, ellos/ellas/ustedes están
Examples of Regular and Irregular Verbs
To solidify your understanding of regular and irregular verbs, let’s examine some specific examples. These examples will illustrate the conjugation patterns and irregularities discussed in the previous sections.
Regular Verb Examples
The following table provides examples of regular verbs conjugated in the present tense. Notice how the stems remain consistent and the endings follow the standard patterns.
| Pronoun | Hablar (to speak) | Comer (to eat) | Vivir (to live) |
|---|---|---|---|
| Yo (I) | Hablo | Como | Vivo |
| Tú (You, informal) | Hablas | Comes | Vives |
| Él/Ella/Usted (He/She/You, formal) | Habla | Come | Vive |
| Nosotros (We) | Hablamos | Comemos | Vivimos |
| Vosotros (You, informal plural – Spain) | Habláis | Coméis | Vivís |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Hablan | Comen | Viven |
| Example Sentence | Yo hablo español. (I speak Spanish.) | Él come una manzana. (He eats an apple.) | Nosotros vivimos en Madrid. (We live in Madrid.) |

| Example Sentence | Nosotros hablamos inglés. (We speak English.) | Yo como pescado. (I eat fish.) | Tú vives en Londres. (You live in London.) |
As you can see, the stems of these verbs (habl-, com-, viv-) remain consistent throughout the conjugation. The endings are the only parts that change, following the standard patterns for -ar, -er, and -ir verbs.
Irregular Verb Examples
Now, let’s examine some examples of irregular verbs. These verbs deviate from the standard conjugation patterns in various ways.
Stem-Changing Verb (e → ie): Pensar (to think)
| Pronoun | Pensar (to think) |
|---|---|
| Yo (I) | Pienso |
| Tú (You, informal) | Piensas |
| Él/Ella/Usted (He/She/You, formal) | Piensa |
| Nosotros (We) | Pensamos |
| Vosotros (You, informal plural – Spain) | Pensáis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Piensan |
| Example Sentence | Yo pienso que es una buena idea. (I think it’s a good idea.) |
| Example Sentence | Tú piensas mucho. (You think a lot.) |
| Example Sentence | Él piensa en su futuro. (He thinks about his future.) |

| Example Sentence | Tú puedes hablar español. (You can speak Spanish.) |
| Example Sentence | Ella puede venir mañana. (She can come tomorrow.) |
| Example Sentence | Nosotros podemos ir al parque. (We can go to the park.) |
Notice how the stem changes from pod- to pued- in all forms except nosotros and vosotros.
Irregular Yo Form: Hacer (to do/make)
| Pronoun | Hacer (to do/make) |
|---|---|
| Yo (I) | Hago |
| Tú (You, informal) | Haces |
| Él/Ella/Usted (He/She/You, formal) | Hace |
| Nosotros (We) | Hacemos |
| Vosotros (You, informal plural – Spain) | Hacéis |
| Ellos/Ellas/Ustedes (They/You, formal plural) | Hacen |
| Example Sentence | Yo hago la tarea. (I do the homework.) |
| Example Sentence | Tú haces un buen trabajo. (You do a good job.) |
| Example Sentence | Él hace una casa. (He makes a house.) |
| Example Sentence | Nosotros hacemos la cena. (We make dinner.) |
Notice how only the yo form (hago) is irregular. The remaining forms follow the regular -er conjugation pattern.
Completely Irregular Verb: Ir (to go)
| Pronoun | Ir (to go) |
|---|---|
| Yo (I) | Voy |
| Tú (You, informal) | Vas |
| Él/Ella/Usted (He/She/You, formal) | Va |

| Example Sentence | Tú vas a la playa. (You go to the beach.) |
| Example Sentence | Él va al trabajo. (He goes to work.) |
| Example Sentence | Nosotros vamos a la fiesta. (We go to the party.) |
As you can see, all forms of the verb ir are irregular and don’t follow any standard conjugation patterns. These forms must be memorized individually.
Usage Rules
Understanding the usage rules for regular and irregular verbs is crucial for constructing grammatically correct sentences. While regular verbs follow predictable patterns, irregular verbs require careful attention to their specific forms and contexts.
Regular Verb Usage
Regular verbs are generally straightforward to use. Once you understand the conjugation patterns for -ar, -er, and -ir verbs, you can apply these patterns to a wide range of verbs. However, it’s important to remember that regular verbs can still be used in various tenses and moods, each with its own set of conjugation rules.
For example, the regular verb caminar (to walk) can be used in the present tense (yo camino, tú caminas, etc.), the preterite tense (yo caminé, tú caminaste, etc.), the imperfect tense (yo caminaba, tú caminabas, etc.), and other tenses. In each tense, the verb follows the standard conjugation pattern for -ar verbs.
Irregular Verb Usage
Irregular verbs require more attention to detail. Because their forms deviate from the standard patterns, it’s essential to memorize their conjugations in different tenses and moods. Additionally, some irregular verbs have specific usage rules that must be followed.
For example, the verb ser (to be) is used to describe permanent characteristics, identity, origin, and time. The verb estar (to be), on the other hand, is used to describe temporary states, location, and conditions. Using the correct verb in the appropriate context is crucial for accurate communication.
Common Mistakes
Many learners of Spanish make common mistakes when conjugating regular and irregular verbs. Being aware of these mistakes can help you avoid them in your own speaking and writing.
- Incorrect stem changes: Forgetting to apply stem changes in the correct forms or applying them incorrectly is a common mistake. For example, saying “Yo puedo” instead of “Yo puedo” (for the verb poder) is a frequent error.
- Confusing ser and estar: Using ser when estar is required or vice versa is a common mistake, as these verbs have distinct meanings and usages. For example, saying “Yo soy cansado” instead of “Yo estoy cansado” is incorrect because estar is used to describe a temporary state (tiredness).
- Incorrect irregular yo forms: Forgetting the irregular yo form of verbs like hacer, poner, and salir is a common mistake. For example, saying “Yo hago” instead of “Yo hago” (for the verb hacer) is a frequent error.
- Misconjugating completely irregular verbs: Completely irregular verbs like ir and ser have unpredictable forms that must be memorized. Misconjugating these verbs is a common mistake. For example, saying “Yo era” instead of “Yo fui” in the preterite tense of the verb ir is incorrect.
Here are some examples of common mistakes with corrections:
| Incorrect | Correct | Explanation |
|---|---|---|
| Yo puedo ir. | Yo puedo ir. | Stem change is required (o → ue). |
| Yo soy cansado. | Yo estoy cansado. | Estar is used for temporary states. |
| Yo hago la tarea. | Yo hago la tarea. | Irregular yo form is required. |
| Yo era al cine. | Yo fui al cine. | Ir is completely irregular in the preterite. |

Advanced Topics
For advanced learners of Spanish, understanding the nuances of verb conjugation in different moods is essential. The subjunctive and imperative moods, in particular, require a deeper understanding of verb forms and their usage.
Subjunctive Mood
The subjunctive mood is used to express doubt, uncertainty, wishes, emotions, and hypothetical situations. Conjugating verbs in the subjunctive mood requires a different set of endings than the indicative mood. The present subjunctive is formed by taking the yo form of the present indicative, dropping the -o, and adding the subjunctive endings. Regular verbs follow this pattern, while irregular verbs may have stem changes or irregular forms.
For example, the present subjunctive of hablar is formed by taking the yo form (hablo), dropping the -o, and adding the subjunctive endings: hable, hables, hable, hablemos, habléis, hablen.
Irregular verbs like tener and poder have stem changes in the present subjunctive: tenga, tengas, tenga, tengamos, tengáis, tengan; pueda, puedas, pueda, podamos, podáis, puedan.
Imperative Mood
The imperative mood is used to give commands or instructions. The imperative forms are derived from the present subjunctive and the tú form of the present indicative. For regular verbs, the tú form of the imperative is the same as the third-person singular of the present indicative (e.g., habla for hablar). For irregular verbs, the imperative forms may be irregular.
For example, the imperative forms of hablar are: habla (tú), hable (usted), hablemos (nosotros), hablad (vosotros), hablen (ustedes).
Irregular verbs like tener and ir have irregular imperative forms: ten (tú), tenga (usted), tengamos (nosotros), tened (vosotros), tengan (ustedes); ve (tú), vaya (usted), vamos (nosotros), id (vosotros), vayan (ustedes).
