Spanish Conjugation: Your Ultimate Guide to Conjugating Any Spanish Verb

Did you know that Spanish verbs will look different depending on the subject, the tense and the mood of the verb?

That’s what Spanish conjugation is! And it’s important that you know how it works so you can communicate effectively and accurately.

In this post, I’ll walk you through the fundamentals of Spanish verb conjugation, starting with the most basic rules and then working through irregularities and other wrinkles.

The Basics of Spanish Conjugation

When conjugating Spanish verbs in the present tense, you first need to identify who’s performing the action. This is your “subject.” There are eight possible subjects:

Note: vosotros/vosotras is a regional pronoun used only in Spain; it’s replaced by ustedes in the rest of the Spanish-speaking world.

Now that we know who’s performing the action, we’ll need to conjugate by picking the correct verb ending depending on who the subject is.

Spanish verb infinitives (a.k.a. the dictionary version of the verb) end in the letters -ar, -er or -ir.

To conjugate an infinitive, you need to remove the final two letters and add the appropriate ending.

To find the appropriate ending, you will need to consider which tense and mood you’re using and whether the verb is regular or irregular.

Regular Verbs in the Present Tense

The Spanish present tense is used for facts that are true in the current moment and general statements:

Yo quiero un gato. (I want a cat.)

Yo hablo español. (I speak Spanish.)

It’s the most basic and common Spanish tense, so it’s the ideal place for beginner conjugators to get started.

-ar verbs

Here’s how you’d conjugate hablar (to speak). You use the same verb endings to conjugate other regular -ar verbs.

-er verbs

For regular -er verbs, such as comer (to eat):

-ir verbs

For regular -ir verbs, such as vivir (to live):

Here are a few examples of this tense in action:

Antonio canta por las mañanas. (Antonio sings in the mornings.)

Mi sobrino come mucho. (My nephew eats a lot.)

Patricia vive en Madrid. (Patricia lives in Madrid.)

Reflexive Verbs in the Present Tense

Reflexive verbs perform an action on themselves. That is, they have a subject that’s the same as the object, such as in the sentence “I weigh myself.”

You can spot these in Spanish because their infinitive verb form often includes a pronoun, for example:

• lavarse (to wash oneself)
• bañarse (to bathe oneself)
• despertarse (to wake oneself up)

To conjugate reflexive verbs, you’ll also need to choose the appropriate reflexive pronoun, to indicate the subject/object relationship.

The following reflexive pronouns can be used for reflexive verbs in any tense:

You’ll typically place the reflexive pronoun right before the conjugated verb.

Here are some examples:

Pedro se ducha todos los días. (Pedro showers [himself] every day.)

Siempre me acuesto a las 10. (I always go to bed at 10 p.m.)

¿Por qué no te afeitas? (Why don’t you shave [yourself]?)

Conjugating in the Present Progressive Tense

The present progressive tense is used to refer to actions happening right now. In the English language, this would refer to verbs ending in -ing.

To form sentences in the present progressive, you must first know how to conjugate the verb estar (to be):

Then, change the ending of the action verb as follows:

• -ar to -ando
• -er/ir to -iendo

Let’s look at escribir (to write) as an example. To say “I am writing” in Spanish, we will:

1. Conjugate estar in the yo form→ estoy.
2. Change the ending of escribir→ escribiendo.
3. Combine the two to get Estoy escribiendo (I am writing).

Here are a few more examples:

Mi vecino está llorando. (My neighbor is crying.)

Estamos bebiendo café. (We’re drinking coffee.)

Estoy escribiendo un correo electrónico. (I’m writing an email.)

Conjugating in the Past Tense

The past tense, or the preterite, refers to the simplest form of the Spanish past tense. In English, conjugating to the past tense would typically involve adding the suffix -ed to a verb.

Basically, use this tense to talk about things that have already happened.

-ar verbs

The following table will show you how to conjugate -ar verbs in the past tense:

-er / -ir verbs

In this verb tense, the -er and -ir forms have the same ending:

Note the placement of accents in this verb tense: They’re important but are only used for the first and third person.

Here are a few examples:

Anabel comió pizza anoche. (Anabel ate pizza last night.)

Vivieron 10 años en Buenos Aires. (They lived in Buenos Aires for 10 years.)

Ayer llamamos a nuestra abuela. (We called our grandma yesterday.)

Conjugating in the Future Tense

Many consider the future tense to be one of the easiest to conjugate in Spanish.

When you conjugate Spanish verbs to the future tense, you simply add the ending to the end of the infinitive form of a verb. The ending will be the same for all verbs.

Here are the verb endings for the future tense:

Check out a few more examples of the future tense at work:

Mañana lloverá. (It’ll rain tomorrow.)

Serás muy feliz aquí. (You’ll be very happy here.)

Iremos a dormir muy pronto. (We’ll go to sleep very soon.)

Note that the future tense is reserved for a slightly more distant future. This tense is often not used for something that will happen in the very near future (as in hours or minutes).

When something is happening relatively soon, but still somewhat in the future, you’d more often use the present tense, or the ir + a + infinitive form, to describe this.

Irregular Verbs

In Spanish, many verbs don’t follow the rules of conjugation that we’ve covered. These are called irregular verbs.

Irregular verbs are very common and in most cases, you’ll just have to memorize their special conjugations.

Stem-changing Verbs

Stem-changing verbs have the same conjugations as regular verbs. Their irregularity is seen when their stem—the part that remains when you drop the -ar / -er / -ir ending— changes.

There are four main types of stem changes that can occur:

• E → IE 
• O → UE
• E → I
• U → UE 

This is what those stem changes would look like using the yo form as an example:

• Querer → Quiero
• Poder → Puedo 
• Decir — Digo
• Jugar — Juego 

The stem change applies to all forms of the verb except the nosotros and vosotros forms.

Irregular Yo Forms

Some verbs are only irregular when you conjugate them to their yo form. There are various kinds of verbs that have irregular yo forms. 

Some verbs will end in -go, -oy,  or -zco.  Verbs that end in -ger or -gir will end in -jo. 

These are only a few of the patterns and the only way to really remember them is to memorize which verbs follow them.

Here are a few examples of verbs with irregular yo forms:

Salgo (I leave)

Soy (I am)

Conozco (I know)

Sé (I know)

Extingo (I extinguish)

Escojo (I choose)

Spelling-changing Verbs

Some verbs change their spelling when they’re conjugated a certain way. You can see an example of this with -uir words.

They’re conjugated normally for the most part, but the i becomes y in all forms except for nosotros and vosotros.

Here are some examples: 

• incluir (to include) → ella incluye (she includes)
• huir (to run away) → ellos huyen (they run away)
• destruir (to destroy) → yo destruyo (I destroy)

Another example is verbs ending in -cer and -cir. To keep the “th” sound, the letter z is used in the first person conjugation (I).

If there’s a consonant before -cer / -cir, the c changes into a z:

• vencer (to defeat) → yo venzo (I defeat)

If there’s a vowel before -cer / -cir, the z is added before the c:

• producir (to produce) → yo produzco (I produce)

Special Irregular Verbs

There are some special irregular verbs that just completely drop all rules and do their own thing. It’s best to just memorize these verbs and forms.

Two of the most common verbs with special irregular forms that you need to remember are ser (to be) and ir (to go).

Here’s how you conjugate ser in the present tense:

And here’s how you conjugate ir in the present tense:

How to Practice Conjugating Spanish Verbs
