Null Object Omission

Level 3

In spoken Portuguese, speakers often omit the direct object (like 'it' or 'them') if the listener already knows what is being discussed. Instead of saying 'I saw it,' you simply say 'I saw.'

How It Works

The Null Object Omission is a defining feature of spoken Portuguese. It occurs when a transitive verb is used without an object because the referent is already clear from the context.

Key Rules:

  • 3rd Person Only: You can only drop 'it', 'him', 'her', or 'them'. You can never drop 1st or 2nd person pronouns like me, te, or nos.
  • Direct Objects Only: This omission applies to direct objects. For verbs requiring prepositions (like gostar de or precisar de), you either drop the entire prepositional phrase or use the preposition plus a pronoun (e.g., 'Gosta do livro?' -> 'Gosto' or 'Gosto dele').
  • Short Answers: The most frequent everyday context for the null object in both dialects is in short answers to yes/no questions (e.g., 'Você viu o filme?' -> 'Vi.'). This works so well for both animate and inanimate objects because the language is actually eliding the entire Verb Phrase (VP Ellipsis), not just dropping the pronoun.
  • Specific vs. Generic: Both European Portuguese (EP) and Brazilian Portuguese (BP) freely allow the omission of indefinite objects (like mass nouns or bare plurals).
  • Animate vs. Inanimate: In BP, the null object is the overwhelming preference for inanimate things (books, keys). For specific human referents, spoken BP strongly prefers subject pronouns (e.g., 'Vi ele'), though they can still be dropped in short answers or parallel structures. Register Clash Warning: Using the formal clitics (o/a) in casual spoken BP sounds actively unnatural, while using 'ele/ela' as a direct object in Portugal immediately identifies the speaker as using a Brazilian pattern. In EP, overt clitics are strongly preferred for human referents, and animate null objects are pragmatically dispreferred.
  • Topicalization: Moving the object to the start of the sentence (topicalization) and omitting it after the verb is a signature BP feature: 'Esse livro, eu já li Ø'. Note that EP allows topicalization both with and without the clitic (e.g., 'Esse livro, já o li' or 'Esse livro, já li').
  • Syntactic Constraints: In EP, null objects are restricted in compound tenses and generally cannot be used inside a 'syntactic island' (like a relative clause). In BP, they are 'syntactically unrestricted' and appear freely in almost any structure, including inside these complex syntactic islands.
  • Recipe Register: In both dialects, null objects are standard in instructional texts like recipes (e.g., 'Corte o tomate em cubos e cozinhe Ø por 10 minutos').

Examples (4)

  1. — Você comprou o pão? — Comprei.

    — Did you buy the bread? — I bought [it].

    Word by Word: — You bought the bread? — [I] bought.

    In this common exchange, the object 'pão' is omitted in the response because it is clear what was bought.

  2. — Onde está a minha chave? — Não sei, perdi.

    — Where is my key? — I don't know, I lost [it].

    Word by Word: — Where is the my key? — Not know, [I] lost.

    The verb 'perder' (to lose) is transitive, but the object 'it' is dropped in speech.

  3. — Já leste este livro? — Já li.

    — Have you read this book? — I've already read [it].

    Word by Word: — Already [you] read this book? — Already [I] read.

    Common in both Portugal and Brazil, the 'it' is understood without needing a pronoun.

  4. — Vi o filme ontem e adorei.

    — I saw the movie yesterday and loved [it].

    Word by Word: — [I] saw the movie yesterday and [I] loved.

    The second verb 'adorar' drops the object because 'o filme' was just mentioned.

Common Mistakes

  • Dropping 1st or 2nd person objects (me/you).

    Você viu Ø na festa?
    Você me viu na festa?

    You can only drop 3rd person objects (it/him/her). If you mean 'Did you see ME?', you must include the pronoun 'me'.

  • Using a null object in compound tenses in European Portuguese.

    Eu tenho lido Ø. (EP context)
    Tenho-o lido. (EP) / Eu tenho lido. (BP)

    In European Portuguese, compound tenses usually block the null object. However, in Brazilian Portuguese, dropping the object in compound tenses like 'Eu já tinha visto' is perfectly natural.

Learn This First

To understand null object omission, you first need to know what a direct object pronoun is (like 'o' or 'a') so you can recognize its absence. You also need a basic grasp of the past tense (Pretérito Perfeito) since this omission frequently occurs when reporting past actions.
