Hacer Preterite Conjugation: Conjugate the Irregular Verb Hacer in Spanish

If you're learning Spanish, you've probably run into the verb hacer (to do/to make) a million times already. It's one of those verbs that shows up everywhere. The thing is, when you need to talk about what you did or made in the past, hacer gets a little weird. Let me walk you through exactly how to conjugate hacer in the preterite tense, show you the full chart, and give you some real examples so this actually makes sense.

The hacer preterite conjugation chart

Here's what you came for. The full conjugation table for hacer in the preterite tense:

Notice anything strange? The stem changes from "hac" to "hic" for most forms, and then to "hiz" for the third person singular. That's the irregular part. Regular verbs in Spanish would just keep their stem and add endings.

Why is hacer irregular in the preterite

Hacer is what we call an irregular verb in Spanish, specifically in the preterite tense. The irregularity comes from a stem change that affects all the conjugations.

Most regular Spanish verbs ending in -er would follow a predictable pattern in the preterite. Think of a verb like comer (to eat): comí, comiste, comió, comimos, comisteis, comieron. Clean and simple.

Hacer throws that pattern out the window. The stem becomes "hic" for most forms, but here's where it gets interesting: for the third person singular (él/ella/usted), it becomes "hizo" instead of "hició." Why? Because in Spanish, you can't have "ci" before "o" in this context. The language prefers "zo" to maintain the sound. It's a spelling convention that keeps pronunciation consistent.

Subjunctive preterite forms

Okay, this gets a bit more advanced, but if you're serious about learning Spanish, you should know that hacer also has preterite subjunctive forms. There are actually two sets: the imperfect subjunctive (which, confusingly, is based on the preterite) and the future subjunctive (which barely exists in modern Spanish).

The imperfect subjunctive has two acceptable forms in Spanish:

Both are correct, though the -ra forms are more common in modern Spanish, especially in Latin America.

You'd use these in sentences like "Si hiciera buen tiempo, iríamos a la playa" (If the weather were good, we would go to the beach) or "Me pidió que hiciera la tarea" (He asked me to do the homework).

Preterite tense vs. Other past tenses

Here's the thing about Spanish grammar: there are multiple ways to talk about the past, and they're not interchangeable.

Common phrases and examples with hacer in the preterite

Let me give you some real examples you'll encounter:

Hacer preterite in different Spanish dialects

The conjugation stays the same across Spanish dialects, which is great news. Whether you're learning Mexican Spanish, Argentinian Spanish, or Spanish from Spain, "hice" is "hice" everywhere.

The main difference is with the vosotros form. In Latin America, vosotros isn't used in everyday speech. Instead, ustedes serves as both the formal and informal plural "you." So Latin American speakers would say "¿Qué hicieron ustedes?" where Spaniards might say "¿Qué hicisteis vosotros?"

Some regions also use "vos" instead of "tú" (mainly Argentina, Uruguay, and parts of Central America), but the preterite form stays the same: "vos hiciste" uses the same conjugation as "tú hiciste."
