To conjugate abrir (to open), drop the -ir ending and add standard -ir endings for all tenses, but remember the past participle is the irregular abierto.
Learning how to conjugate abrir helps you describe everything from opening a door to starting a business. This verb appears frequently in daily conversation. Unlike many Spanish verbs that undergo stem changes, abrir remains regular in its stem. The only major irregularity you must memorize is its past participle form. This guide breaks down every tense, mood, and form you need to master this essential verb.
The Basics: Verb Forms of Abrir
Before moving into specific tenses, you need three foundational forms. These non-finite forms do not change based on the subject. You use them to build complex sentences and continuous actions.
| Form | Spanish | English |
|---|---|---|
| Infinitive | Abrir | To open |
| Gerund | Abriendo | Opening |
| Past Participle | Abierto | Opened |
Irregularity Note: Many students mistakenly say “abrido.” This is incorrect. Always use abierto when forming perfect tenses (like “have opened”) or using it as an adjective (like “the open door”).
Present Indicative Tense
You use the present indicative to discuss habits, current actions, or general truths. Since abrir is a regular -ir verb here, you simply remove the -ir and add the endings: -o, -es, -e, -imos, -ís, -en.
| Pronoun | Conjugation | Example |
|---|---|---|
| Yo | Abro | Abro la ventana. |
| Tú | Abres | ¿Abres la tienda hoy? |
| Él/Ella/Usted | Abre | Ella abre el regalo. |
| Nosotros/as | Abrimos | Abrimos los libros. |
| Vosotros/as | Abrís | Abrís la puerta. |
| Ellos/Ellas/Ustedes | Abren | Ellos abren a las ocho. |
Usage in Context
The present tense covers more than just the exact moment of speaking. You can use it to ask for instructions or offer help.
- Requesting help:¿Abres esto por favor? — Will you open this for me please?
- Describing routines:Nunca abro el correo los domingos. — I never open mail on Sundays.
- Scheduling:El banco abre mañana. — The bank opens tomorrow.
Conjugate Abrir in Spanish Preterite Tense
The preterite tense describes actions completed in the past at a specific time. Use this when you opened something yesterday, last week, or at a precise moment. The endings are regular for -ir verbs: -í, -iste, -ió, -imos, -isteis, -ieron.
| Pronoun | Conjugation | English Meaning |
|---|---|---|
| Yo | Abrí | I opened |
| Tú | Abriste | You opened |
| Él/Ella/Usted | Abrió | He/She/You opened |
| Nosotros/as | Abrimos | We opened |
| Vosotros/as | Abristeis | You all opened |
| Ellos/Ellas/Ustedes | Abrieron | They/You opened |
Examples of Completed Actions
Note how the nosotros form (abrimos) is identical in both present and preterite tenses. Context tells you which one is intended.
- Specific moment:Él abrió la carta inmediatamente. — He opened the letter immediately.
- Sequence of events:Llegué a casa y abrí la puerta. — I arrived home and opened the door.
Imperfect Indicative Tense
The imperfect tense sets the scene in the past. It describes repeated actions (used to open) or actions that were in progress when something else happened (was opening). The endings follow the regular pattern for -er/-ir verbs: -ía, -ías, -ía, -íamos, -íais, -ían.
| Pronoun | Conjugation | English Meaning |
|---|---|---|
| Yo | Abría | I used to open |
| Tú | Abrías | You used to open |
| Él/Ella/Usted | Abría | He/She used to open |
| Nosotros/as | Abríamos | We used to open |
| Vosotros/as | Abríais | You all used to open |
| Ellos/Ellas/Ustedes | Abrían | They used to open |
Future and Conditional Tenses
These two tenses are among the easiest for students because you do not remove the infinitive ending. You attach the new endings directly to “abrir”.
Simple Future
Use the future tense to say what “will” happen. The endings are -é, -ás, -á, -emos, -éis, -án.
- Yo abriré (I will open)
- Tú abrirás (You will open)
- Él abrirá (He will open)
- Nosotros abriremos (We will open)
- Vosotros abriréis (You all will open)
- Ellos abrirán (They will open)
Conditional
Use the conditional to express what “would” happen, often in polite requests or hypothetical situations. The endings match the imperfect tense but are attached to the full infinitive.
- Yo abriría (I would open)
- Tú abrirías (You would open)
- Él abriría (He would open)
- Nosotros abriríamos (We would open)
- Vosotros abriríais (You all would open)
- Ellos abrirían (They would open)
Subjunctive Mood: Present and Imperfect
The subjunctive mood expresses doubt, desires, or possibilities. If you say “I hope that you open the door,” you must use the subjunctive because you cannot guarantee the action will happen.
Present Subjunctive
Form this by taking the yo form of the present indicative (abro), dropping the -o, and adding opposite endings (using -a for -ir verbs): -a, -as, -a, -amos, -áis, -an.
| Pronoun | Conjugation | Example |
|---|---|---|
| Yo | Abra | Espero que yo abra… |
| Tú | Abras | Quiero que abras la caja. |
| Él/Ella/Usted | Abra | Es posible que ella abra. |
| Nosotros/as | Abramos | Dudan que abramos. |
| Vosotros/as | Abráis | Espero que abráis. |
| Ellos/Ellas/Ustedes | Abran | Ojalá abran pronto. |
Imperfect Subjunctive
Use this for past doubts or unlikely conditions (“If I opened…”). There are two variations, but the -ra endings are more common in speech.
- Yo abriera (or abriese)
- Tú abrieras (or abrieses)
- Él abriera (or abriese)
- Nosotros abriéramos (or abriésemos)
- Vosotros abrierais (or abrieseis)
- Ellos abrieran (or abriesen)
Imperative Commands with Abrir
When you need to tell someone to open something directly, use the imperative mood. The forms change depending on whether the command is affirmative (do it) or negative (don’t do it) and how formal you wish to be.
| Person | Affirmative | Negative |

| Tú (Informal) | Abre | No abras |
| Usted (Formal) | Abra | No abra |
| Nosotros | Abramos | No abramos |
| Vosotros | Abrid | No abráis |

Frequently Asked Questions
Is abrir a stem-changing verb?
No, abrir is not a stem-changing verb. Its stem remains abr- throughout all regular conjugations in the present, past, and future. You do not need to change vowels in the root, which makes it easier to learn than verbs like cerrar (to close), which changes e to ie.
What is the difference between abrir and inaugurar?
While both mean “to open,” abrir is the general term for physical objects (doors, eyes) or starting generic events. Inaugurar is more formal and specific, often used for grand openings of buildings, art exhibitions, or official ceremonies. You would abrir a window, but inaugurar a museum.
How do you conjugate abrir in the continuous tense?
To say “I am opening,” use the verb estar conjugated in the present tense followed by the gerund abriendo. For example: Estoy abriendo la caja (I am opening the box). This structure emphasizes that the action is happening right at this specific moment.
Can abrir be used reflexively?
Yes, abrirse is the reflexive form. It implies something opens by itself or describes an emotional state. For example, La puerta se abrió means “The door opened” (on its own or seemingly so), whereas Abro la puerta implies “I open the door.”
What is the positive informal command for abrir?
The positive informal command (tú) is abre. You use this with friends, family, or children. For example, Abre tus regalos means “Open your gifts.” Do not confuse it with the negative command, which changes to no abras.
