Active and passive voice in Spanish : complete course

What Are Active and Passive Voice in Spanish?

In Spanish, just like in English, you can say the same thing in two different ways. La voz activa y pasiva (the active and passive voice) refers to how a sentence is structured depending on who does the action and who receives it. In the active voice, the subject performs the action. In the passive voice, the subject receives the action instead.

Understanding this concept will help you read Spanish texts more confidently and express yourself with more variety.

Simple Examples to Get Started

• Active: El chef cocina la paella. (The chef cooks the paella.)
• Passive: La paella es cocinada por el chef. (The paella is cooked by the chef.)

See how the focus shifts? In the first sentence, the chef is doing something. In the second, the paella is at the center of attention.

The Key Elements of Active and Passive Voice in Spanish

Let us explore the main building blocks of this grammar concept.

1. The Active Voice (La Voz Activa)

In an active sentence, the structure follows a simple pattern:

• María escribe una carta. (María writes a letter.)
• Los estudiantes leen el libro. (The students read the book.)

This is the most common and natural structure in everyday Spanish. The subject is always the one doing the action.

2. The Passive Voice with ‘Ser’ (La Voz Pasiva con Ser)

This is the most formal type of passive voice in Spanish. It uses the verb ser followed by a past participle. The past participle must agree in gender and number with the subject.

Note that leído agrees with el libro (masculine singular), and escrita agrees with la carta (feminine singular).

3. The Reflexive Passive with ‘Se’ (La Pasiva Refleja)

In spoken Spanish, people rarely use the formal passive with ser. Instead, they often use se + verb. This structure is very common and sounds more natural.

• Se venden pisos aquí. (Apartments are sold here.)
• Se habla español en este restaurante. (Spanish is spoken in this restaurant.)
• Se firmó el contrato ayer. (The contract was signed yesterday.)

This form is especially useful when the agent (the person doing the action) is unknown or not important.

Why Active and Passive Voice Matter in Spanish

You might wonder: do I really need to learn the passive voice? The answer is yes, for several reasons.

• Reading comprehension: Passive sentences appear often in news articles, official documents, and literature. Recognizing them will help you understand complex texts.
• Writing skills: Using the passive voice can make your writing sound more formal and varied.
• Natural speech: The se passive is used all the time in everyday conversations. You will hear it in shops, on the radio, and in daily life.
• Avoiding repetition: The passive allows you to shift focus without repeating the subject unnecessarily.

Comparison with Other Languages

If you already speak French or English, here is a helpful comparison:

As you can see, the structure is very similar in all three languages. The main difference in Spanish is the frequent use of the se passive, which has no exact equivalent in English or French. Also, remember that Spanish past participles must agree in gender and number with the subject, which is not required in English.

A Complete Example in Context

Let us look at a short paragraph using both active and passive voice:

El arquitecto diseñó el edificio en 1990. El edificio fue inaugurado por el alcalde un año después. Hoy, se organizan visitas culturales cada semana.

Translation: The architect designed the building in 1990. The building was inaugurated by the mayor one year later. Today, cultural visits are organized every week.

• First sentence: active voice — the architect is the subject doing the action.
• Second sentence: passive with ser — the building receives the action, the agent is the mayor.
• Third sentence: reflexive passive with se — no specific agent is mentioned.

Key Takeaways

• The active voice is the most common structure: subject + verb + object.
• The passive voice with ser is formal and follows: subject + ser + past participle + por + agent.
• The reflexive passive with se is used in everyday speech when the agent is unknown or unimportant.
• Past participles must agree in gender and number with the subject in passive constructions with ser.
• Reading Spanish news or formal texts is a great way to practice recognising passive structures.
