Have you ever wanted to say “I did,” “she made,” or “they did” in Spanish but stopped because the verb hacer suddenly changed to something that did not look familiar? You are not alone.
Hacer is one of the most useful Spanish verbs, but its past tense forms can be confusing because it is an irregular verb.
The good news is that you do not need to memorize a huge set of complicated rules. The most important past form is the Spanish preterite, which is used for completed actions in the past. In this tense, hacer becomes hice, hiciste, hizo, hicimos, hicisteis, and hicieron.
This guide explains hacer past tense conjugation in simple English. You will learn how to form the verb, how to use it in everyday sentences, how the preterite differs from the imperfect, and which mistakes beginners often make.
By the end, you should be able to use hacer naturally when talking about things you did or made in the past.
Quick Answer
The most common past tense conjugation of hacer is its preterite form. It is used for completed actions in the past.
- Yo hice = I did / I made
- Tú hiciste = You did / You made
- Él/Ella hizo = they did / made
- Nosotros hicimos = We did / made
- Vosotros hicisteis = You all did / made
- Ellos hicieron = They did / made
Example: Ayer hice la tarea. = “Yesterday, I did my homework.”
The imperfect forms are different: hacía, hacías, hacía, hacíamos, hacíais, hacían. These describe ongoing, repeated, or habitual actions in the past.
What Is Hacer Past Tense Conjugation?
Hacer is a Spanish verb that usually means “to do” or “to make.” It is also used in many common expressions involving weather, time, activities, and other situations.
When we talk about hacer past tense conjugation, we change hacer according to the subject and the type of past action we want to describe.
For completed actions, Spanish commonly uses the preterite tense.
For example:
- Hice la cena. = I made dinner.
- Hiciste un buen trabajo. = You did a good job.
- Ella hizo una pregunta. = She asked a question.
- Hicimos el proyecto. = We did the project.
- Ellos hicieron ejercicio. = They exercised.
Notice that hacer does not simply become a regular er verb in the preterite. Instead, its stem changes to hic , with one important spelling change in the third person singular: hizo.
The verb hacer can describe both doing something and making something.
For example:
Ayer hice mi trabajo.
Yesterday, I did my work.
Mi madre hizo un pastel.
My mother made a cake.
The meaning depends on the context.
Structure of Sentences of Hacer Past Tense Conjugation
The basic sentence structure is simple. In a normal Spanish sentence, the subject may come before the conjugated verb, but Spanish often leaves the subject out because the verb ending already tells us who performed the action.
Affirmative sentences
The basic pattern is:
Subject + preterite form of hacer + object/complement
Examples:
- Yo hice la tarea. I did the homework.
- María hizo una comida deliciosa. María made a delicious meal.
- Nosotros hicimos un plan. We made a plan.
The subject can also be omitted:
- Hice la tarea. I did the homework.
- Hicimos un plan. We made a plan.
Negative sentences
The basic pattern is:
Subject + no + preterite form of hacer + object/complement
Examples:
- Yo no hice la tarea. I did not do the homework.
- Ella no hizo la comida. She did not make the food.
- No hicimos nada. We did not do anything.
In Spanish, no normally comes directly before the conjugated verb.
Interrogative sentences
For questions, Spanish can use:
¿Subject + preterite form of hacer + complement?
or simply:
¿Preterite form of hacer + complement?
Examples:
- ¿Hiciste la tarea? Did you do the homework?
- ¿Hizo él la comida? Did he make the food?
- ¿Qué hicieron ustedes? What did you all do?
- ¿Hicimos suficiente? Did we do enough?
Spanish does not need an English style auxiliary such as did to make a past tense question.
Formation of Hacer Past Tense Conjugation
The preterite of hacer is irregular. Instead of keeping the normal hac stem, it uses hic for most forms.
The main forms are:
hice → hiciste → hizo → hicimos → hicisteis → hicieron
The third person singular form is especially important:
hizo, not hico.
This happens because the form uses z before the final o.
There is another useful detail in the third person plural:
hicieron, not hicieron with an extra i after the c. The correct form is simply hicieron.
Because hacer is irregular, learners should memorize its preterite forms rather than trying to build them like a regular er verb.
Contractions
Spanish does not use English style contractions such as I did → I’d for the preterite form of hacer. The conjugated verb remains a single word.
For example:
- Hice el trabajo. I did the work.
- No hice el trabajo. I did not do the work.
How to Use Hacer Past Tense Conjugation
The preterite is mainly used when the action is viewed as completed.
1. Completed actions
Use the preterite when something happened and finished.
- Hice la tarea anoche.
I did the homework last night. - Ella hizo la compra ayer.
She did the shopping yesterday. - Hicimos el trabajo el lunes.
We did the work on Monday.
The action has a clear ending or is presented as a completed event.
2. Something you made
Hacer can mean “to make,” so the preterite is very common when talking about things that someone created or prepared.
- Hice una pizza. I made a pizza.
- Mi hermano hizo un dibujo. My brother made a drawing.
- Ellos hicieron una mesa. They made a table.
3. Activities you did
You can use hacer for many activities.
- Hice ejercicio. I exercised.
- Hicimos una caminata. We went for a walk.
- Hiciste mucho trabajo. You did a lot of work.
4. Weather expressions
Hacer is also used with weather expressions. When describing a specific completed period of weather, the preterite may be appropriate.
- Ayer hizo frío. It was cold yesterday.
- La semana pasada hizo mucho calor. It was very hot last week.
For ongoing background weather, however, Spanish often uses the imperfect:
- Hacía frío cuando salimos. It was cold when we left.
This difference between hizo and hacía is important.
5. Questions about past actions
The preterite is useful when asking what someone did.
- ¿Qué hiciste ayer? What did you do yesterday?
- ¿Qué hizo Ana? What did Ana do?
- ¿Qué hicieron después? What did they do afterward?
A very common everyday question is:
¿Qué hiciste hoy? What did you do today?

Common Mistakes
Mistake 1: Using hico instead of hizo
❌ Ella hico la cena.
✅ Ella hizo la cena.
Hizo is the correct third person singular preterite form.
Mistake 2: Treating hacer like a regular er verb
❌ Yo hací la tarea.
✅ Yo hice la tarea.
Hací is not the preterite form. The correct form is hice.
Mistake 3: Using haciste with the wrong subject
❌ Yo hiciste la tarea.
✅ Yo hice la tarea.
Hiciste is used with tú, while hice is used with yo.
Mistake 4: Adding the English auxiliary “did”
❌ ¿Did hiciste la tarea?
✅ ¿Hiciste la tarea?
Spanish does not need did to form a preterite question.
Mistake 5: Confusing hice and hacía
❌ Cada día hice ejercicio cuando era niño.
Better: Cada día hacía ejercicio cuando era niño.
When an action was a regular or repeated habit in the past, the imperfect is usually more appropriate.
Mistake 6: Using hizo for “I did”
❌ Yo hizo la comida.
✅ Yo hice la comida.
Remember:
Yo → hice
Él/Ella/Usted → hizo
Key Grammar Rules
Rule 1: The preterite of hacer is irregular
Do not form it like a regular er verb.
Correct: hice
Incorrect: hacé or hací for the preterite.
Rule 2: Remember the basic sequence
A useful memory line is:
hice → hiciste → hizo → hicimos → hicisteis → hicieron
Learning these six forms will cover the main subject combinations.
Rule 3: Use hizo for él, ella, and usted
- Él hizo
- Ella hizo
- Usted hizo
All three use hizo.
Rule 4: Do not add “did” to Spanish questions
English says:
Did you do your homework?
Spanish says:
¿Hiciste tu tarea?
The verb form itself shows the past tense.
Rule 5: Use the preterite for completed actions
- Hice el trabajo ayer.
- Hicimos la comida a las ocho.
These actions are presented as completed events.
Rule 6: Use the imperfect for repeated or ongoing past actions
- Hacía ejercicio todos los días.
I used to exercise every day. - Hacíamos la tarea juntos.
We used to do homework together.
The choice depends on how the speaker views the past action.
Comparisons with Similar Grammar Forms
Understanding hacer becomes much easier when you compare its preterite with other forms.
Hacer in the present vs. preterite
Present:
Hago la tarea. I do the homework.
Preterite:
Hice la tarea. I did the homework.
The present describes something happening now or a general action. The preterite presents the action as completed.
Preterite vs. imperfect
This is one of the most important differences for learners.
Preterite:
Ayer hice ejercicio.
I exercised yesterday.
The action is presented as a completed event.
Imperfect:
Cuando era joven, hacía ejercicio todos los días.
When I was young, I used to exercise every day.
The imperfect shows a repeated or habitual past action.
Another example:
Hizo frío anoche.
It was cold last night.
Hacía frío cuando salimos.
It was cold when we left.
The first presents the weather as a completed past situation. The second gives background information around another event.
Preterite vs. present perfect
Spanish also has the present perfect, formed with haber plus the past participle.
He hecho la tarea.
I have done the homework.
Hice la tarea.
I did the homework.
The present perfect connects a past action with the present in ways that depend partly on regional usage. The preterite simply presents the action as a completed past event.
Hacer vs. other common past tense verbs
Learners studying hacer may also want to review other irregular preterite verbs such as tener → tuve, estar → estuve, and poder → pude. These verbs have their own irregular patterns, so they should not be treated as regular verbs.
