What dependo means and its structure
Depender is a verb that means to depend, rely on, or be contingent upon. In Portuguese, many verbs require a preposition to link the verb to its object. Depender is one of these verbs: it must be followed by the preposition de when indicating the person or thing on which someone depends.
The basic structure is: subject + depender (conjugated) + de + object. For example:
Eu dependo de você.
Ele depende do salário.
Nós dependemos da ajuda dos amigos.
Why is de necessary?
Portuguese often uses prepositions to mark the relationship between verbs and their complements. Some verbs take direct objects without prepositions (transitive direct), while others require prepositions (transitive prepositional). Depender is transitive prepositional with the preposition de. Without de, the sentence becomes ungrammatical or changes meaning.
Think of de as a grammatical connector that signals dependency or origin. It clarifies that what follows is the entity that the subject relies on, not a direct object being acted upon.
Compare with English
In English you say I depend on you. The preposition on corresponds to Portuguese de in this context. Direct translation of verbs without adjusting prepositions causes mistakes. Remember: depend + on (English) = depender + de (Portuguese).
Common patterns: verbs that require de
Depender is not unique. Many Portuguese verbs consistently use de to introduce their complement. Familiarize yourself with this group to avoid errors. Examples:
Gostar de (to like) — Eu gosto de música.
Lembrar-se de (to remember) — Ela lembra-se do compromisso.
Precisar de (to need) — Nós precisamos de tempo.
These verbs are part of a larger pattern where de marks relationships like possession, origin, cause, or dependence.
How prepositions combine with articles and pronouns
When de comes before definite articles or certain pronouns, Portuguese contracts the preposition with the article. This affects the form of the phrase after the verb.
Examples with articles:
depende de + o = depende do
depende de + a = depende da
depende de + os = depende dos
depende de + as = depende das
Examples with pronouns do not contract. Use the full pronoun after de:
Eu dependo de você.
Ela depende de mim.
Note on personal pronouns
Personal pronouns used after prepositions keep their stressed forms: mim, você, ele, ela, nós, vocês, eles, elas. Do not use the unstressed clitic forms (me, te, se) after prepositions. For example:
Ele depende de mim. (correct)
Ele depende de me. (incorrect)
Practical examples and context
Seeing verbs in context helps you remember the preposition. Here are several natural Brazilian Portuguese sentences using depender and de.
Eu dependo de você para terminar o projeto.
O sucesso do evento depende do trabalho da equipe.
A previsão do tempo depende das condições atmosféricas.
Ela depende dos pais para pagar os estudos.
O resultado depende de vários fatores.
Notice how de introduces people, things, abstract concepts, and contracted article forms.
Nuances of meaning with different objects
Depending on the complement, nuance in meaning appears. Compare these:
Ele depende de mim para apoio. — He relies on me for support (personal reliance).
Ele depende do apoio financeiro. — He depends on the financial support (object-based reliance).
The grammar stays the same, but the focus moves from person to thing or concept.
Contractions and pronunciation tips
Contractions like do and da are very common in spoken and written Brazilian Portuguese. Pronunciation often blends the preposition and article smoothly: do sounds like /du/ and da like /da/. For learners, practicing these contractions helps speech sound natural.
Examples:
depende do clima — sounds like depende du clima in rapid speech
depende da cidade — sounds like depende da cidade
Formal and colloquial registers
In formal Portuguese, especially in written language, the use of prepositions is strictly adhered to. In colloquial speech, structure remains the same but contractions and dropping of pronouns can occur. However, the omission of de with depender is not acceptable in standard Brazilian Portuguese, even in casual contexts.
Colloquial: Eu dependo de você. (often faster, with contracted sounds)
Incorrect: Eu dependo você. (never correct)
Other verbs with similar behavior
Learning groups of verbs that behave similarly is efficient. Verbs that commonly require de include:
abastecer-se de — to supply oneself with
abster-se de — to abstain from
avisar de — to inform of
desconfiar de — to distrust, suspect
enjoar de — to get tired of
Memorizing such patterns reduces guesswork. When you spot these verbs, prepare to use de before the complement.
Why some verbs differ between languages
Prepositional requirements are language-specific. A verb that is transitive direct in English may be transitive prepositional in Portuguese and vice versa. These differences stem from historical development and idiomatic usage. When learning Portuguese, focus on patterns rather than translating word-for-word.
Common mistakes and how to avoid them
Beginners often omit de or use the wrong preposition. Here are frequent errors and corrections:
Incorrect: Eu dependo você.
Correct: Eu dependo de você.
Incorrect: Depende com o tempo.
Correct: Depende do tempo.
Tip: When in doubt, check a reliable Portuguese dictionary or corpus to see whether a verb is transitive direct or requires a preposition. Practice by reading authentic texts and noting verb-preposition patterns.
Cultural and usage notes
Brazilian Portuguese speakers rely on prepositions to convey subtle relationships in daily speech. Using the correct preposition shows grammatical competence and helps you be understood clearly. In professional or academic settings, accuracy with prepositions like de is especially important.
Also, regional variations in Brazil may affect spoken rhythm and contraction frequency, but the grammatical role of de with depender is universal across Brazilian dialects.
Short exceptions and related verbs
Some verbs related to dependence can appear in different constructions. For example, the reflexive form depender-se is less common and usually appears in specific contexts. More frequently, you will encounter synonyms that use different prepositions or structures, such as:
contar com — to count on (contar com alguém)
confiar em — to trust in (confiar em alguém)
Note how these alternatives use com or em instead of de. Choosing the right verb can change the required preposition, so learn the verb-preposition pair together.
Quick reference: how to conjugate depender
Here are basic present tense forms to use in sentences:
Eu dependo
Tu dependes (less common in Brazil — tu is regional)
Ele / Ela depende
Nós dependemos
Vocês dependem
Eles / Elas dependem
Combine these forms with de and the appropriate complement: Eu dependo de você; Nós dependemos do projeto.
Additional tips for learners
1. Read Brazilian texts and highlight verbs with prepositions to build awareness.
2. Listen to native speakers and note contractions like do/da to improve comprehension.
3. Practice speaking full sentences rather than translating word-for-word from English.
4. Use verb + preposition lists to memorize common patterns.
These strategies will make using depender and many other prepositional verbs feel natural faster.
Conclusion
The preposition de in Eu dependo de você is not optional; it is a grammatical requirement that marks the complement of depender. Learning which verbs require prepositions and practicing them in context will improve your Portuguese fluency. Pay attention to contractions, pronoun forms after prepositions, and alternatives like contar com or confiar em to expand your language toolkit.
