学べること
Ready to make your Portuguese sound truly authentic and sophisticated? This chapter is your gateway to mastering the passive voice, a crucial structure that lets you emphasize actions and results over the person performing them. It's how native speakers convey precision and formality, and you'll find it everywhere from news articles to everyday conversation.
We'll start with the classic ser + past participle construction, learning how to shift the spotlight to the object of the action, ensuring your participles always agree! Then, you'll discover how to gracefully introduce the 'doer' of the action using por (think pelo/pela) when necessary, all while maintaining the passive emphasis.
But the real star of this chapter is the versatile se passive (Voz Passiva Sintética). This is incredibly common in Portuguese, and you'll learn its secrets, especially how the verb must agree in number with the noun being acted upon. Get ready to understand signs like Vendem-se casas (Houses are sold) with perfect clarity. Finally, we'll tackle the subtle but important distinction between the passive se and the impersonal se, so you'll always know when to make your verb plural and when to keep it singular.
By the end of this chapter, you won't just be learning rules; you'll be able to express yourself with greater nuance and sound incredibly natural. You'll comfortably read headlines like
A ponte foi construída(The bridge was built) and understand nuanced impersonal statements. Get ready to elevate your Portuguese to a truly upper-intermediate level!

Overview
A ponte foi construída(The bridge was built) and understand nuanced impersonal statements, equipping you with essential skills for upper-intermediate Portuguese language learning.
How This Grammar Works
O João escreveu o livro(João wrote the book), you'd say
O livro foi escrito pelo João(The book was written by João).
A decisão foi tomada pelos diretores(The decision was made by the directors).
Vendem-se casas(Houses are sold – plural verb for plural 'houses'), and
Aluga-se apartamento(An apartment is rented – singular verb for singular 'apartment'). This is precisely the 'Se' Passive Voice (Vendem-se casas) you'll see everywhere.
Comem-se bem aqui- One eats well here, or People eat well here). Recognizing this difference is a hallmark of advanced Portuguese grammar.
Common Mistakes
- 1✗ Wrong:
A porta foi aberto.
(The door was opened.)
A porta foi aberta.(The door was opened.)
A porta is feminine singular, so the participle must be aberta, not aberto.- 1✗ Wrong:
Vende-se casas.(Houses are sold.)
Vendem-se casas. (Houses are sold.)casas) is plural, the verb must also be plural. Casas is plural, so the verb should be vendem-se, not vende-se.- 1✗ Wrong:
A comida foi preparado por mim.
(The food was prepared by me.)
A comida foi preparada por mim.(The food was prepared by me.)
preparado must agree with A comida (feminine singular), becoming preparada.

Quick FAQ
What's the main difference between Voz Passiva Analítica and Voz Passiva Sintética in Portuguese grammar?
The Voz Passiva Analítica uses ser + past participle (e.g.,
O livro foi escrito), while the Voz Passiva Sintética uses a verb with the particle se (e.g.,
Escreve-se o livro).
How do I know when to use pelo or por with the agent in the passive voice?
You use pelo/pela/pelos/pelas (contractions of por + definite article) when the agent is specific and defined (e.g., pela equipe). You use por alone when the agent is general, indefinite, or not accompanied by an article (e.g., por sorte).
Can I always use the se passive in Portuguese?
No, the se passive is typically used with transitive verbs that have a direct object. It's less common with verbs that express states or verbs that are inherently intransitive. It's also more common in formal or impersonal contexts.
How can I quickly distinguish between passive se and impersonal se?
If the verb *can* agree in number with the noun that follows it (i.e., if that noun is plural and the verb can also be plural), it's likely a passive se. If the verb *always* stays singular, even with a plural concept, it's an impersonal se. (e.g., Comem-se maçãs vs. Come-se bem aqui).
Cultural Context
Aluga-se(For Rent) or
Proíbem-se cães(Dogs are forbidden) everywhere. It's a hallmark of formal writing, news articles, and official announcements, lending an air of objectivity and professionalism.
se passive) is often preferred for its conciseness and natural flow, making it essential for any B2 Portuguese speaker aiming for authentic expression.重要な例文 (6)

Review Summary
- [Subject] + [Ser] + [Past Participle (agrees with subject)]
- [Passive Sentence] + [por + article] + [Agent]
- [Verb 3rd person] + [se] + [Subject]
- [Verb 3rd person singular] + [se] + [Preposition/Adverb]
よくある間違い
In the analytical passive, the past participle acts like an adjective and must agree in gender and number with the subject.
In the 'se' passive, 'quartos' is the subject. Since 'quartos' is plural, the verb 'alugar' must be plural.
To introduce the agent of the passive, use the preposition 'por' (pelo/pela), not 'para'.
