Regular -ar Verbs

The preterite (pretérito indefinido) is the main past tense for completed actions in Spanish. It is the tense you use to say I spoke, she called, we arrived. Regular -ar verbs take a tidy set of endings that you can apply to thousands of verbs.

The Endings

To conjugate a regular -ar verb in the preterite, drop the -ar ending of the infinitive and add the preterite endings.

SubjectEndinghablar
yohablé
-astehablaste
él / ella / ustedhabló
nosotros / nosotras-amoshablamos
ellos / ellas / ustedes-aronhablaron

About Those Accents

Two forms carry a written accent: the yo form () and the él/ella/usted form (). The accent is not decorative — it is essential. Without it, hable would be a present subjunctive form, and hablo would be the present indicative I speak. The accent tells the reader and the pronouncer that the stress lands on the final vowel and that the tense is the past.

Ayer hablé con mi abuela.

Yesterday I spoke with my grandmother.

Ella cantó en el concierto.

She sang at the concert.

💡
Watch out for hablo (I speak, present) vs habló (he/she spoke, preterite). The only visible difference is the accent, but the meaning is completely different.

A Curious Coincidence

The nosotros form hablamos looks identical to the present tense hablamos. Context, not spelling, tells you which one is meant.

Hoy hablamos con Juan.

Today we are speaking with Juan. (present)

Ayer hablamos con Juan.

Yesterday we spoke with Juan. (preterite)

A clear time marker (hoy, ayer, anoche, esta semana) almost always resolves the ambiguity.

Common mistakes

❌ Ayer yo hablo con mi abuela.

Wrong: using the present tense for a past event.

✅ Ayer yo hablé con mi abuela.

Correct: hablé with the accent marks the preterite.

❌ Ella canto en el concierto.

Wrong: missing the accent changes the meaning to present tense 'I sing'.

✅ Ella cantó en el concierto.

Correct: cantó with the accent marks the third-person preterite.

❌ Yo trabajé, tú trabajé, ella trabajé.

Wrong: using the yo ending for all persons.

✅ Yo trabajé, tú trabajaste, ella trabajó.

Correct: each person has its own ending.

❌ Nosotros hablamos ayer. (confused about tense)

Not wrong, but ambiguous — add a time marker to clarify.

✅ Ayer hablamos con Juan.

Correct: the time marker ayer makes the preterite meaning clear.
