The Passive Voice (Leaving Cert Spanish): Revision Notes
The passive voice
Overview
The passive voice in Spanish allows you to express that an action is being done to someone or something, rather than focusing on who is doing the action. It's particularly useful when the person performing the action is unknown, unimportant, or when you want to emphasise the action itself or what receives the action.
In English, we form the passive voice using "to be" + past participle (e.g., "The book is read", "The car was sold"). Spanish offers two main ways to create the passive voice, each serving different purposes in communication.
Understanding the passive voice is essential for advanced Spanish communication, as it allows you to vary your sentence structure and focus attention on different elements of your message.
Rules & formation
Method 1: Using ser + past participle
This method works similarly to English and is formed by combining the appropriate tense of the verb ser (to be) with a past participle.
Step 1: Form the past participle
- For -ar verbs: Remove the infinitive ending and add -ado
- For -er and -ir verbs: Remove the infinitive ending and add -ido
Step 2: Choose the correct tense of ser
- Present passive: es/son (is/are)
- Preterite passive: fue/fueron (was/were)
- Future passive: será/serán (will be)
Step 3: Make the past participle agree The past participle must agree in gender and number with the noun it describes, just like an adjective.
Critical Agreement Rule: The past participle must agree in gender and number with the subject of the sentence. This is one of the most common sources of errors for Spanish learners.
Method 2: Using reflexive se
This method uses the reflexive pronoun se followed by the verb in the third person. This construction is very common in Spanish, though it may sound strange to English speakers as it literally means "it does itself."
The verb form changes depending on whether the noun is singular or plural:
- Singular noun: se + verb (3rd person singular)
- Plural noun: se + verb (3rd person plural)
The reflexive se construction is often preferred in everyday Spanish conversation because it sounds more natural and less formal than the ser + past participle method.
Key forms

|---|---|---|
| is/are | se + verb (3rd sing.) | se + verb (3rd pl.) |
| was/were | se + verb (3rd sing. pret.) | se + verb (3rd pl. pret.) |
| will be | se + verb (3rd sing. fut.) | se + verb (3rd pl. fut.) |
Example sentences
Using ser + past participle
Worked Example: Preterite Passive Construction
El coche fue vendido la semana pasada. The car was sold last week.
Analysis: "fue" (was) + "vendido" (sold) creates the preterite passive, emphasising that the car received the action of being sold.
Worked Example: Present Passive Construction
El sitio web es usado principalmente por los jóvenes. The website is mainly used by young people.
Analysis: This present passive construction shows an ongoing state or regular occurrence.
Worked Example: Gender and Number Agreement
Los ordenadores son apagados al final de la clase. The computers are turned off at the end of the lesson.
Analysis: Notice how "apagados" agrees with the masculine plural noun "ordenadores."
Using reflexive se
Worked Example: Reflexive Se Construction
El sitio web se usa principalmente para bajar música. The website is mainly used for downloading music.
Analysis: This reflexive construction is more common in Spanish and focuses on the action happening to the website.
Worked Example: Future Tense with Reflexive Se
Se publicarán los resultados la semana próxima. The results will be published next week.
Analysis: The future tense with reflexive se emphasises that the publishing will happen.
Common mistakes & tips
Agreement Errors
Remember that with ser + past participle, the past participle must agree with the subject in gender and number. A common mistake is forgetting this agreement:
- ❌ La habitación fue limpiado (incorrect - masculine ending with feminine noun)
- ✅ La habitación fue limpiada (correct - feminine ending matches feminine noun)
Tense Selection
Choose your tense by looking at the English "to be" verb:
- "is/are" → present tense
- "was/were" → preterite tense
- "will be" → future tense
Preference in Usage
While the ser + past participle construction exists, Spanish speakers often prefer the reflexive se construction in everyday speech, especially for general statements or when no specific agent is mentioned.
Reflexive Se Agreement
Remember that with reflexive se, the verb agrees with the subject (singular or plural), not with se itself. The verb form must match whether the noun is singular or plural.
Summary
Key Points to Remember:
- The passive voice has two main forms: ser + past participle and reflexive se
- Past participles from -ar verbs end in -ado, while -er/-ir verbs end in -ido
- With ser + past participle, the past participle must agree in gender and number
- Reflexive se construction is more commonly used in everyday Spanish
- Choose your tense based on the English "to be" verb (is/are, was/were, will be)
