Definition of -IR Verbs

In Spanish, verbs are categorized into three conjugations based on their infinitive endings: -ar, -er, and -ir. Verbs ending in -ir form the third group. The infinitive form is the verb’s base form, like “to live” in English. Therefore, -ir verbs are those whose infinitives end in -ir, such as vivir (to live), escribir (to write), and sentir (to feel). Understanding how to conjugate these verbs is essential for forming sentences in various tenses.

The function of -ir verbs is identical to that of -ar and -er verbs; they denote actions, states, or processes. They appear in all tenses and moods, fulfilling the same grammatical roles as other verb types. The key difference lies in their conjugation patterns, which must be learned and applied correctly to ensure grammatical accuracy.

Context is crucial when using any verb. The specific -ir verb selected depends on the action or state you want to describe. For example, you would use abrir (to open) when talking about opening a door, and cubrir (to cover) when talking about covering something with a blanket. The tense and mood of the verb will depend on when the action takes place and the speaker’s attitude toward it.

Structural Breakdown of -IR Verbs

To conjugate -ir verbs, you generally remove the -ir ending from the infinitive to obtain the verb’s stem. This stem is then combined with specific endings that indicate the tense, mood, and person (who is performing the action). The endings for -ir verbs are similar to those of -er verbs in some tenses, but differ in others, especially in the present tense.

For example, let’s take the verb vivir (to live). Removing the -ir gives us the stem viv-. To conjugate in the present tense, we add the following endings:

• Yo: -o (vivo)
• Tú: -es (vives)
• Él/Ella/Usted: -e (vive)
• Nosotros/Nosotras: -imos (vivimos)
• Vosotros/Vosotras: -ís (vivís)
• Ellos/Ellas/Ustedes: -en (viven)

Therefore, the present tense conjugation of vivir is: vivo, vives, vive, vivimos, vivís, viven.

Regular -IR Verbs

Regular -ir verbs follow predictable conjugation patterns. Once you understand the basic structure, conjugating these verbs becomes straightforward. The key is to memorize the endings for each tense and apply them consistently to the verb stem.

Let’s look at a few more examples of regular -ir verbs:

• Abrir (to open)
• Admitir (to admit)
• Compartir (to share)
• Decidir (to decide)
• Definir (to define)

The following table shows the present tense conjugation of compartir (to share):

Pronoun	Conjugation
Yo	Comparto
Tú	Compartes
Él/Ella/Usted	Comparte
Nosotros/Nosotras	Compartimos
Vosotros/Vosotras	Compartís
Ellos/Ellas/Ustedes	Comparten

The following table shows the preterite tense conjugation of abrir (to open):

Pronoun	Conjugation
Yo	Abrí
Tú	Abriste
Él/Ella/Usted	Abrió
Nosotros/Nosotras	Abrimos
Vosotros/Vosotras	Abristeis
Ellos/Ellas/Ustedes	Abrieron

Irregular -IR Verbs

Irregular -ir verbs do not follow the standard conjugation patterns. Their irregularity can manifest in various ways, such as changes in the verb stem or the addition of unexpected endings. These verbs require memorization of their specific conjugations.

Common irregular -ir verbs include:

• Ir (to go) – This is one of the most irregular verbs in Spanish.
• Venir (to come)
• Dormir (to sleep) – (o -> ue stem change)
• Sentir (to feel) – (e -> ie stem change)

The present tense conjugation of ir (to go) is:

Pronoun	Conjugation
Yo	Voy
Tú	Vas
Él/Ella/Usted	Va
Nosotros/Nosotras	Vamos
Vosotros/Vosotras	Vais
Ellos/Ellas/Ustedes	Van

The preterite tense conjugation of venir (to come) is:

Pronoun	Conjugation
Yo	Vine
Tú	Viniste
Él/Ella/Usted	Vino
Nosotros/Nosotras	Vinimos
Vosotros/Vosotras	Vinisteis
Ellos/Ellas/Ustedes	Vinieron

Stem-Changing -IR Verbs

Stem-changing -ir verbs undergo a change in the stem vowel in certain conjugations, particularly in the present tense and preterite tense. These changes typically involve:

• e -> ie (e.g., sentir – to feel)
• e -> i (e.g., pedir – to ask for)
• o -> ue (e.g., dormir – to sleep)

These changes occur in all forms except nosotros and vosotros in the present tense. In the preterite, e -> i stem changes occur in the él/ella/usted and ellos/ellas/ustedes forms only.

Let’s examine the present tense conjugation of sentir (to feel):

Pronoun	Conjugation
Yo	Siento
Tú	Sientes
Él/Ella/Usted	Siente
Nosotros/Nosotras	Sentimos
Vosotros/Vosotras	Sentís
Ellos/Ellas/Ustedes	Sienten

The preterite tense conjugation of pedir (to ask for) is:

Pronoun	Conjugation
Yo	Pedí
Tú	Pediste
Él/Ella/Usted	Pidió
Nosotros/Nosotras	Pedimos
Vosotros/Vosotras	Pedisteis
Ellos/Ellas/Ustedes	Pidieron

Reflexive -IR Verbs

Reflexive verbs are used when the subject of the verb performs the action on themselves. These verbs are typically identified by the reflexive pronoun se attached to the infinitive (e.g., vestirse – to get dressed). When conjugating a reflexive verb, the reflexive pronoun must be placed before the conjugated verb and adjusted to match the subject.

The reflexive pronouns are:

• Yo: me
• Tú: te
• Él/Ella/Usted: se
• Nosotros/Nosotras: nos
• Vosotros/Vosotras: os
• Ellos/Ellas/Ustedes: se

Let’s look at the present tense conjugation of vestirse (to get dressed):

Pronoun	Conjugation
Yo	Me visto
Tú	Te vistes
Él/Ella/Usted	Se viste
Nosotros/Nosotras	Nos vestimos
Vosotros/Vosotras	Os vestís
Ellos/Ellas/Ustedes	Se visten

Usage Rules for -IR Verbs

The general rules for using -ir verbs are similar to those for -ar and -er verbs. The verb must agree in number and person with the subject of the sentence. The tense of the verb must accurately reflect the time frame of the action. However, there are some specific considerations:

• Stem Changes: Be mindful of stem-changing verbs, especially in the present and preterite tenses. Remember that the nosotros and vosotros forms typically do not undergo stem changes in the present tense.
• Irregular Verbs: Irregular verbs must be memorized individually. There are no shortcuts for these verbs.
• Reflexive Verbs: Always include the appropriate reflexive pronoun when using reflexive verbs. The placement of the pronoun is crucial for grammatical correctness.

For example, consider the sentence “I feel happy.” The correct translation is “Me siento feliz” (using the reflexive verb sentirse and the appropriate reflexive pronoun me). A common mistake would be to say “Yo siento feliz,” which is grammatically incorrect.

Common Mistakes with -IR Verbs

Several common mistakes are frequently made by learners when using -ir verbs. Being aware of these errors can help you avoid them.

• Incorrect Stem Changes: Applying stem changes to the nosotros and vosotros forms in the present tense when they shouldn’t be applied.
• Misconjugating Irregular Verbs: Failing to memorize the irregular forms and applying regular conjugation patterns instead.
• Omitting Reflexive Pronouns: Forgetting to include the reflexive pronoun when using reflexive verbs.
• Using Incorrect Endings: Confusing -ir verb endings with -ar or -er verb endings.

Here are some examples of common mistakes and their corrections:

Incorrect	Correct	Explanation
Nosotros sintemos	Nosotros sentimos	Stem change should not occur in the nosotros form of sentir in the present tense.
Yo sabo (instead of sé, from the verb saber)	Yo sé	The verb saber (to know) is irregular in the yo form.
Yo visto	Me visto	The verb vestirse (to get dressed) is reflexive, so the reflexive pronoun me is required.
Tú comes (when you want to use the verb compartir)	Tú compartes	Using the incorrect -er ending for an -ir verb.

   • Formal vs. Informal Usage: The choice of -ir verb and its conjugation can also depend on the level of formality. Using usted instead of tú, for example, requires a different verb form.

   Understanding these advanced topics will allow you to use -ir verbs with greater precision and confidence, making your Spanish sound more natural and nuanced.
