Introduction
Learning the difference between similar verbs can be confusing for English-speaking learners of Portuguese. This article explains the correct patterns for using depender de versus using depender alone in Brazilian Portuguese. You will learn when the preposition is required, how to conjugate, common collocations, and real example sentences to build confidence.
What does depender mean?
Depender is a verb that means to depend, to rely, or to be contingent on something. In Portuguese the verb most commonly appears with a preposition to link it to what it depends on. Understanding the required structures helps avoid mistakes and makes your speech more natural.
Basic sense and translation
In English you often say depend on. In Portuguese the basic equivalent is depender de. When something requires another thing, you normally use the preposition de after the verb. For example:
O sucesso depende do esforço.
Here the structure is verb + preposition + noun. The preposition de is essential to show the relationship between the action and the object it depends on.
When to use depender de
The rule of thumb: use depender de when you want to indicate what something depends on or who someone depends on. This pattern is by far the most frequent and grammatically correct in most contexts.
Depender de + noun or pronoun
Use depender de when the dependent element is a noun, a noun phrase, or a pronoun. Examples:
A decisão depende das informações disponíveis.
Ela depende dos pais para morar.
Isso depende de você.
Depender de + verb (infinitive or clause)
You can also use depender de before an infinitive or a subordinate clause introduced by que. When the dependent element is an action or a whole idea, keep the preposition:
Tudo depende de fazer um bom planejamento.
Se depender de mim, vamos começar hoje.
Vai depender do que ele decidir.
Agreement with articles and contractions
When the object includes a definite article, de contracts with the article in Portuguese. For masculine singular o, de + o becomes do. For plural or feminine forms the contractions are das, dos, da depending on gender and number.
O resultado depende do tempo.
A resposta depende das circunstâncias.
When can depender appear without de?
Although depender de is the default, there are limited situations where depender appears without the preposition. These cases are mostly idiomatic, elliptical, or involve passive and pronominal uses.
Pronominal use: depender-se seldom used
Portuguese permits pronominal reflexive forms of many verbs by adding -se. With depender, depender-se exists but is rare and somewhat formal or literary. It emphasizes that the subject depends on itself or expresses a reflexive nuance. In everyday Brazilian Portuguese you will seldom hear it.
Ele não se depende de ninguém. (uncommon)
More natural: Ele não depende de ninguém.
Ellipsis and answers in conversation
In casual speech you might hear depende alone as a one-word answer to mean it depends. This is not using the verb without the preposition in a full sentence, but rather a conversational shorthand where the rest of the phrase is implied.
Vamos ao parque hoje?
Depende. (implying depende do tempo, depende de você, etc.)
Set phrases and compound verbs
There are also compound or idiomatic expressions where depender is part of a larger structure and the preposition might not be placed directly after it. Even so, the meaning of dependence remains linked to some complement and often the preposition is still present elsewhere in the sentence.
Ele depende financeiramente dos pais, mas emocionalmente está bem.
Grammar: syntax and verb patterns
Understanding the syntactic pattern helps you form correct sentences. The verb depender is intransitive and normally requires a prepositional complement introduced by de. It is not a transitive verb that takes a direct object without a preposition.
Verb transitivity and arguments
In grammatical terms, depender is intransitive-prepositional, meaning it needs a preposition to introduce its complement. Compare with transitive verbs in English that take a direct object without a preposition. Trying to use depender without de followed by a noun will generally be incorrect.
Incorrect: Isso depende ele.
Correct: Isso depende dele.
Personal pronouns after depender de
When the complement is a personal pronoun, use the prepositional pronoun forms: mim, você, ele, ela, nós, vocês, eles, elas. For example:
O projeto depende de mim.
Ela depende de você para a tradução.
Use with que clauses
When the complement is a subordinate clause, the pattern is depender de + que + clause or simply depender + que in spoken Portuguese, though the preposition is still standard in writing. Preferred formal structure:
Tudo depende de que você esteja preparado.
Colloquially people often say: Depende que você esteja preparado. Avoid this in formal writing.
Conjugation and sample sentences
Here are some common conjugations of depender with examples in Brazilian Portuguese to show usage across tenses and persons.
Present indicative

Tu dependes

Vocês/eles dependem
Example: Eu dependo do transporte público para ir ao trabalho.

Common mistakes and how to avoid them
English speakers often make predictable errors with depender. Here are the main ones and how to fix them.
Omitting the preposition
Incorrect: Eu dependo minha família.
Correct: Eu dependo da minha família.
Remember that depender typically needs de before the complement.
Using object pronouns incorrectly
Incorrect: Isso depende ele.
Correct: Isso depende dele.
Use prepositional pronouns after de: mim, comigo, contigo, dele, dela, etc.
Confusing depende with prevalence of other verbs
Students sometimes mix up depender with verbs like precisar or contar com. These verbs have different structures and meanings. Compare:
Eu preciso de ajuda. (I need help.)
Eu dependo de ajuda. (I depend on help.)
Eu conto com sua ajuda. (I count on your help.)
Nuances of meaning and usage notes
Although depender de usually translates to depend on, slight differences exist in nuance between Portuguese and English depending on context.
Dependency vs contingency
Sometimes depender de expresses contingency rather than personal dependence. For example:
O horário depende do trânsito.
Here it means the time is contingent on traffic conditions, not that the schedule personally relies on traffic.
Politeness and indirectness
Using depende as a short reply can be useful to sound less direct. In Portuguese, this can soften refusals or avoid committing, similar to English.
Você pode vir amanhã?
Depende. (This leaves room for conditions to be discussed.)
Regional and register variations
Brazilian Portuguese speakers commonly use depender de across registers. In very informal speech contractions and omissions occur, but standard written and spoken Brazilian Portuguese will favor the prepositional construction.
Real-life examples from Brazilian contexts
Seeing phrases in real cultural contexts helps internalize patterns. Here are examples you might hear in Brazil.
1. No trabalho
Tudo depende do chefe, então precisamos apresentar um bom plano.
2. Com amigos
Vamos à praia amanhã? Depende do tempo e do trabalho.
3. Na família
Ela depende dos avós para cuidar das crianças durante o dia.
4. Em notícias
A economia do país depende das exportações de commodities.
Quick reference cheat sheet
Use this short guide when you need a quick decision about structure.
– Use depender de + noun/pronoun when showing what something depends on.
– Conjugate depender normally; the preposition stays before the complement.
– Short answer depende is fine in conversation, but the full sentence needs de.
– Avoid dropping de in writing; it is almost always required for clarity.
Conclusion
Mastering the difference between depender de and depender is straightforward once you remember that depender is typically intransitive-prepositional and requires de to introduce its complement. Use de with nouns, pronouns, infinitives, and clauses, and rely on conversational shorthand like depende only in casual replies. With the examples and rules here, you can speak and write more confidently in Brazilian Portuguese.
