What are Irregular Verbs in Spanish?
Irregular verbs in Spanish are verbs that do not follow the standard conjugation patterns of regular verbs. Unlike regular verbs, which have predictable endings based on their infinitive form (-ar, -er, or -ir), irregular verbs have unique conjugations in one or more tenses. These irregularities can occur in the stem of the verb, the endings, or both. Mastering these verbs is essential for accurate and fluent Spanish communication.
Irregular verbs are not random; they often fall into specific categories based on the type of irregularity they exhibit. These categories include stem-changing verbs, verbs with an irregular yo form, radical irregular verbs, and orthographic-changing verbs. Each category has its own set of rules and patterns, which can help learners to memorize and understand the conjugations.
Understanding irregular verbs is fundamental to Spanish grammar because they are frequently used in everyday conversation and writing. Many common verbs, such as ser (to be), estar (to be), tener (to have), and ir (to go), are irregular. Therefore, a solid grasp of these verbs is essential for effective communication in Spanish.
Structural Breakdown of Verb Conjugations
To understand irregular verbs, it’s helpful to first review the basic structure of Spanish verb conjugations. A verb conjugation consists of two main parts: the stem and the ending. The stem is the base part of the verb, while the ending indicates the tense, mood, and person (who is performing the action).
For regular verbs, the stem is usually obtained by removing the infinitive ending (-ar, -er, or -ir) from the verb. The appropriate ending is then added to the stem based on the tense and person. However, irregular verbs deviate from this pattern. The stem or the ending, or both, may change in unpredictable ways, requiring learners to memorize the specific conjugations for each irregular verb.
Here’s a basic example comparing a regular and irregular verb in the present tense:
- Regular Verb (Hablar – to speak): Yo hablo, tú hablas, él/ella/usted habla, nosotros hablamos, vosotros habláis, ellos/ellas/ustedes hablan.
- Irregular Verb (Tener – to have): Yo tengo, tú tienes, él/ella/usted tiene, nosotros tenemos, vosotros tenéis, ellos/ellas/ustedes tienen.
Notice how the verb “tener” changes in the yo form (“tengo”), while the regular verb “hablar” follows a predictable pattern. This difference highlights the importance of recognizing and learning irregular verb conjugations.
Types of Irregularities
Spanish irregular verbs can be categorized into several types based on the nature of their irregularity. Understanding these categories can help learners to identify and memorize the conjugations more effectively.
Stem-Changing Verbs
Stem-changing verbs, also known as radical-changing verbs, are verbs in which the vowel in the stem changes when conjugated in certain tenses. These changes typically occur in the present tense and sometimes in the preterite (past) tense. The most common stem changes are:
- E to IE
- O to UE
- E to I
- U to UE (less common)
E to IE Stem-Changing Verbs
In E to IE stem-changing verbs, the “e” in the stem changes to “ie” in all forms except nosotros and vosotros. Common verbs in this category include pensar (to think), querer (to want), and empezar (to begin).
For example, let’s look at the conjugation of pensar (to think) in the present tense:
- Yo pienso
- Tú piensas
- Él/ella/usted piensa
- Nosotros pensamos
- Vosotros pensáis
- Ellos/ellas/ustedes piensan
O to UE Stem-Changing Verbs
In O to UE stem-changing verbs, the “o” in the stem changes to “ue” in all forms except nosotros and vosotros. Common verbs in this category include poder (to be able to), dormir (to sleep), and volver (to return).
For example, let’s look at the conjugation of poder (to be able to) in the present tense:
- Yo puedo
- Tú puedes
- Él/ella/usted puede
- Nosotros podemos
- Vosotros podéis
- Ellos/ellas/ustedes pueden
E to I Stem-Changing Verbs
In E to I stem-changing verbs, the “e” in the stem changes to “i” in all forms except nosotros and vosotros. This stem change also occurs in the preterite tense in the third-person singular and plural forms (él/ella/usted and ellos/ellas/ustedes). Common verbs in this category include pedir (to ask for), servir (to serve), and repetir (to repeat).
For example, let’s look at the conjugation of pedir (to ask for) in the present tense:
- Yo pido
- Tú pides
- Él/ella/usted pide
- Nosotros pedimos
- Vosotros pedís
- Ellos/ellas/ustedes piden
U to UE Stem-Changing Verbs
The U to UE stem change is less common. The “u” in the stem changes to “ue” in all forms except nosotros and vosotros. The most common verb in this category is jugar (to play).
For example, let’s look at the conjugation of jugar (to play) in the present tense:
- Yo juego
- Tú juegas
- Él/ella/usted juega
- Nosotros jugamos
- Vosotros jugáis
- Ellos/ellas/ustedes juegan
Irregular Yo Form Verbs
Irregular yo form verbs are verbs that have an irregularity only in the yo (I) form of the present tense. All other forms are regular. Common verbs in this category include hacer (to do/make), poner (to put), saber (to know), salir (to leave), traer (to bring), and ver (to see).
For example, let’s look at the conjugation of hacer (to do/make) in the present tense:
- Yo hago
- Tú haces
- Él/ella/usted hace
- Nosotros hacemos
- Vosotros hacéis
- Ellos/ellas/ustedes hacen
Radical Irregular Verbs
Radical irregular verbs, also known as “boot verbs,” have significant stem changes in the preterite tense. These changes affect the entire stem, not just a single vowel. Common verbs in this category include estar (to be), tener (to have), poder (to be able to), poner (to put), saber (to know), and venir (to come).
For example, let’s look at the conjugation of tener (to have) in the preterite tense:
- Yo tuve
- Tú tuviste
- Él/ella/usted tuvo
- Nosotros tuvimos
- Vosotros tuvisteis
- Ellos/ellas/ustedes tuvieron
Orthographic-Changing Verbs
Orthographic-changing verbs are verbs that have spelling changes to maintain the correct pronunciation. These changes typically occur when the verb ending is added to the stem. Common verbs in this category include verbs ending in -car, -gar, -zar, and -ger/-gir.
For example:
- -car: buscar (to look for) – Yo busqué (preterite)
- -gar: llegar (to arrive) – Yo llegué (preterite)
- -zar: empezar (to begin) – Yo empecé (preterite)
- -ger/-gir: coger (to grab) – Yo cojo (present)

Usage Rules for Irregular Verbs
Using irregular verbs correctly requires understanding the specific rules and patterns that govern their conjugations. Here are some key rules to remember:
- Stem-Changing Verbs: Remember that stem changes typically occur in the present tense and sometimes in the preterite tense. The nosotros and vosotros forms generally do not undergo stem changes in the present tense.
- Irregular Yo Form Verbs: These verbs only have an irregularity in the yo form of the present tense. All other forms are regular.
- Radical Irregular Verbs: These verbs have significant stem changes in the preterite tense. Memorize the specific stem changes for each verb.
- Orthographic-Changing Verbs: Pay attention to the spelling changes that occur to maintain correct pronunciation. These changes typically involve adding or removing letters when the verb ending is added to the stem.
It’s also important to note that some verbs may have multiple irregularities. For example, a verb may be both stem-changing and have an irregular yo form. In these cases, you need to apply both sets of rules to conjugate the verb correctly.
Additionally, context is crucial when choosing the correct tense and mood. Consider the time frame, the speaker’s attitude, and the relationship between the speaker and the listener to select the appropriate verb form.
Common Mistakes with Irregular Verbs
Learning irregular verbs can be challenging, and it’s common for learners to make mistakes. Here are some frequent errors to watch out for:
- Incorrect Stem Changes: Applying stem changes to the nosotros and vosotros forms in the present tense.
- Forgetting Irregular Yo Forms: Conjugating the yo form of irregular yo form verbs as if they were regular.
- Misusing Radical Irregular Verbs: Failing to recognize and apply the stem changes in the preterite tense.
- Ignoring Orthographic Changes: Not making the necessary spelling changes to maintain correct pronunciation.
Here are some examples of common mistakes and their corrections:
| Incorrect | Correct | Explanation |
|---|---|---|
| Nosotros pensamos (incorrect stem change) | Nosotros pensamos (no stem change) | Stem changes do not occur in the nosotros form in the present tense. |
| Yo hago (correct) | Yo hago (correct) | “Hacer” has irregular yo form. |
| Yo tení (incorrect preterite) | Yo tuve (correct preterite) | “Tener” is a radical irregular verb in the preterite tense. |
| Yo buscé (incorrect orthography) | Yo busqué (correct orthography) | Verbs ending in -car change to -qué in the yo form of the preterite. |
| Ellos duermenos (incorrect conjugation) | Ellos duermen (correct conjugation) | “Dormir” is O – UE stem changing verb and this form is correct. |
