Regular -ar verbs drop -ar and use -o, -as, -a, -amos, -áis, -an in the present tense.
Regular -ar verbs are the easiest place to build Spanish momentum. Once the ending pattern is in your ear, new verbs feel less like new grammar and more like new vocabulary.
This article gives you a clean system: what to change, what to keep, and how to practice so the right ending shows up when you speak.
What An -Ar Verb Is
Most Spanish verbs appear in dictionaries as infinitives. Many infinitives end in -ar, like hablar (to speak) or trabajar (to work).
That -ar ending tells you which family the verb belongs to. For regular -ar verbs, you remove -ar, then attach endings that match the subject.
Stem And Ending: The Two Parts You Use
- Stem: the part you keep (habl- from hablar).
- Ending: the part you swap (hablo, hablas).
How To Conjugate -Ar Verbs In Spanish In The Present Tense
The present tense powers daily Spanish. It handles what you do, what you like, what you need, and what you want.
Start with one model verb, then reuse the same ending set with new stems. Hablar works well as your model.
Step 1: Drop -Ar
Take the infinitive and remove -ar. With hablar, the stem is habl-.
Step 2: Add The Ending For The Subject
Spanish endings change with the person doing the action. You can say the subject pronoun, yet Spanish often leaves it out because the ending carries the meaning.
Present Tense Endings For Regular -Ar Verbs
- yo: -o
- tú: -as
- él / ella / usted: -a
- nosotros / nosotras: -amos
- vosotros / vosotras: -áis
- ellos / ellas / ustedes: -an
Step 3: Say The Full Forms Out Loud
Attach each ending to the stem: hablo, hablas, habla, hablamos, habláis, hablan.
Read them in a steady rhythm, then say them from memory. Your mouth learns the pattern through repetition and timing.
When To Use Subject Pronouns
Spanish often drops subject pronouns because the verb ending already points to the subject. Still, pronouns show up a lot in real speech.
Use them when you need contrast, when the subject could be unclear, or when you want polite distance with usted.
Three Common Moments Pronouns Show Up
- Contrast:Yo trabajo, tú descansas.
- Clarity:Ella canta after several names in a story.
- Polite Tone:¿Usted habla inglés?
Endings That Stay Clear When You Speak
In writing, -as and -an look different. In fast speech, they can blur if you let the last vowel fade.
Practice with a clean finish on the final vowel. A small “tap” at the end keeps the ending sharp.
One Fast Drill For Daily Practice
Pick one verb and run it through the six people while you walk or do chores. Keep a beat: one form per step, one form per breath.
Swap in a new verb each day. The goal is speed with clean endings, not long sessions.
Vosotros, Ustedes, And The “You” Options
Spanish has more than one way to say “you,” and -ar verb endings change with that choice. Most learners start with tú (informal, one person) and usted (polite, one person).
For groups, ustedes is the common option across Latin America and it also works in formal settings in Spain. In Spain, vosotros is used for an informal group, so you’ll see the -áis ending a lot in media from Spain.
A Quick Swap Trick For Speaking
Pick one sentence and flip only the “you” word and the ending. That keeps your attention on the sound change, not on new vocabulary.
- Tú hablas español.
- Usted habla español.
- Ustedes hablan español.
- Vosotros habláis español.
Accent Marks You’ll See On -Ar Endings
The vosotros present ending has an accent: -áis. In the preterite, -é and -ó also carry accents.
When you write, keep those marks in place. When you read, let them guide stress so your pronunciation stays consistent.
Model Sentences With Common Regular -Ar Verbs
After the endings, the next win is useful vocabulary. Start with verbs that fit into plain sentences you can say right away.
Read each mini sentence aloud, then swap the subject to force the endings to change while the meaning stays steady.
| -Ar Verb | Core Meaning | Mini Sentence |
|---|---|---|
| hablar | to speak | Hablo con mi hermana. |
| trabajar | to work | Trabajamos los lunes. |
| estudiar | to study | Estudias español en casa. |
| mirar | to watch / look | Miran la película. |
| escuchar | to listen | Escucha música ahora. |
| viajar | to travel | Viajo en tren. |
| necesitar | to need | Necesito agua. |
| comprar | to buy | Compras pan temprano. |
| cocinar | to cook | Cocinamos arroz. |
| llamar | to call | Llaman a su amigo. |
| ayudar | to help | Ayudas a tu vecino. |
| caminar | to walk | Caminan al parque. |
Stem-Changing -Ar Verbs In The Present Tense
Some -ar verbs keep the same endings yet change a vowel inside the stem for most forms. These are called stem-changing verbs.
The change usually hits the stressed syllable, so it shows up in yo, tú, él/ella/usted, ellos/ellas/ustedes. It usually does not show up in nosotros or vosotros.
Three Stem Change Patterns You’ll See
- o → ue:contar becomes cuento.
- e → ie:cerrar becomes cierro.
- u → ue:jugar becomes juego.
How To Practice Stem Changes Without Confusion
Learn each verb as a set of four changed forms plus two unchanged forms. Say them in this order: yo, tú, él, nosotros, vosotros, ellos.
That order makes the pattern audible. You’ll feel when the stem shifts and when it stays flat.
Preterite Forms For Regular -Ar Verbs
The preterite tense is for finished actions, often tied to a specific time. It’s the tense you use for “I called,” “we studied,” “they walked.”
For regular -ar verbs, you keep the stem and use a new set of endings.
Preterite Endings For Regular -Ar Verbs
- yo: -é
- tú: -aste
- él / ella / usted: -ó
- nosotros / nosotras: -amos
- vosotros / vosotras: -asteis
- ellos / ellas / ustedes: -aron
Notice the accent marks on -é and -ó. They keep pronunciation clear and stop mix-ups with other words.
Spelling Changes In The Preterite Yo Form
Some verbs change spelling right before the -é ending to keep the same sound. The ending set stays the same.
With -car, c changes to qu: buscar → busqué. With -gar, g changes to gu: pagar → pagué. With -zar, z changes to c: empezar → empecé.
Imperfect Forms For Regular -Ar Verbs
The imperfect tense is for habitual actions in the past, background description, and ongoing past scenes. It often matches “used to” or “was doing.”
Regular -ar imperfect endings are consistent, and the stem stays the same.
Imperfect Endings For Regular -Ar Verbs
- yo: -aba
- tú: -abas
- él / ella / usted: -aba
- nosotros / nosotras: -ábamos
- vosotros / vosotras: -abais
- ellos / ellas / ustedes: -aban
The accent in -ábamos matters. It marks stress and keeps the word shape consistent when you read.
Two Handy “Later” Constructions With -Ar Verbs
Spanish has easy ways to talk about plans and actions in progress without changing the main verb endings much. These two patterns show up early in real conversation.
They pair a helper verb with your -ar infinitive or gerund, so you can build longer sentences fast.
Plan Pattern: Ir A + Infinitive
Conjugate ir, then add a, then keep the -ar verb in the infinitive. The -ar verb stays unchanged: voy a hablar, vamos a estudiar.
This is a go-to structure when you mean “going to.” It’s direct and common.
In-Progress Pattern: Estar + Gerund
Conjugate estar, then add the gerund. For -ar verbs, the gerund ends in -ando: hablando, trabajando, mirando.
Use it for “am/are/is doing” actions: Estoy hablando. You can also combine it with time words: Estamos trabajando ahora.
Commands With -Ar Verbs
Commands are where -ar verbs start to feel flexible. The good news is that many command forms reuse patterns you’ve already learned.
Start with the most common ones: informal tú commands and polite usted commands.
Informal Tú Commands
The affirmative tú command for regular -ar verbs matches the present tense él/ella/usted form: Habla, Trabaja, Escucha.
The negative tú command uses no plus the present subjunctive form: No hables, No trabajes, No escuches.
Polite Usted Commands
Polite commands also use the present subjunctive: Hable, Trabaje, Escuche. These often show up in service settings and formal requests.
Some spelling-change verbs keep the sound in these forms too, like busque and pague.
Conjugation Snapshot You Can Reuse
When you’re studying, it helps to keep one compact map of the patterns. Use the table below as a reference, then practice by writing your own sentences with one verb at a time.
| Form | Build It | With Hablar |
|---|---|---|
| Present | stem + -o/-as/-a/-amos/-áis/-an | hablo, hablas, habla… |
| Preterite | stem + -é/-aste/-ó/-amos/-asteis/-aron | hablé, hablaste, habló… |
| Imperfect | stem + -aba/-abas/-aba/-ábamos/-abais/-aban | hablaba, hablabas, hablaba… |
| Plan Pattern | ir + a + infinitive | voy a hablar |
| In Progress | estar + -ando | estoy hablando |
| Tú Command | affirmative: present él form | habla |
| Usted Command | present subjunctive | hable |
A Practice Plan That Builds Speed And Accuracy
Grammar sticks when you use it in small, repeatable steps. A short plan beats a long cram session.
Use these steps with a notebook, flashcards, or voice notes on your phone.
Five Steps
- Pick one verb and write the six present forms.
- Say the six forms out loud twice, then hide them and say them again.
- Write three short sentences with different subjects.
- Switch the tense for those sentences: preterite or imperfect.
- End with one command and one “going to” plan sentence.
If you get stuck, slow down and chant the endings alone: o, as, a, amos, áis, an. Then put them back on the stem and try again right away.
Do the same routine with a new verb each day for a week. After that, mix verbs you already know with one new verb so recall stays sharp.
