The Passive Voice & Passive se

📌 Nota gramatical

In the analytical passive voice (formed with 'ser' + past participle), the past participle functions like an adjective and must agree in gender (masculine/feminine) and number (singular/plural) with the grammatical subject.

📌 Nota gramatical

The analytical passive voice can be used in any tense. The auxiliary verb 'ser' changes to match the tense of the original active sentence, while the main verb remains in the past participle and agrees with the subject.

📌 Nota gramatical

When the doer of the action is specified in a passive sentence, they are introduced by the preposition 'por'. When 'por' combines with definite articles, it contracts (por + o = pelo, por + a = pela, por + os = pelos, por + as = pelas).

📌 Nota gramatical

The passive 'se' is widely used in European Portuguese instead of the analytical passive when the agent is unknown or unimportant. With a singular direct object, the verb remains in the singular and precedes 'se'.

📌 Nota gramatical

When using the passive 'se', the verb must agree in number with the grammatical object (which acts as the subject). If the noun is plural, the verb must also be plural.

📌 Nota gramatical

When an indirect object pronoun (like lhe, lhes, nos) is present, European Portuguese rules of enclisis and proclisis apply. In neutral declarative clauses starting a sentence, the pronoun attaches to the verb after 'se' (mesoclisis or hyphenation rules depending on triggers), but typically 'se' remains attached to the verb.

📌 Nota gramatical

The analytical passive ('ser' + participle) explicitly mentions or implies an agent and focuses on the result of an action. The passive 'se' focuses on the general process without any specific agent, making it more idiomatic in everyday Portuguese.

📌 Nota gramatical

When a modal verb (like 'poder', 'dever', 'querer') precedes a passive structure, the modal conjugates, followed by 'ser' and the past participle, or by the passive 'se' construction.

📌 Nota gramatical

The passive 'se' has a direct object that becomes the subject (e.g., 'Vendem-se casas'). The indefinite 'se' occurs with intransitive or transitive verbs with a preposition, where there is no object, and the verb is always singular (e.g., 'Vive-se bem em Portugal').

📌 Nota gramatical

To form the passive voice in the simple past, use the preterite of 'ser' ('foi' / 'foram') combined with the past participle of the main verb, ensuring agreement with the subject.

📌 Nota gramatical

In subordinate clauses, European Portuguese often employs the personal infinitive in passive contexts to maintain clarity about who or what receives the action.

📌 Nota gramatical

When an action involves direct object pronouns that would clash with 'se', European Portuguese speakers naturally prefer active phrasing or restructuring to avoid stylistic awkwardness.
