B1 (Intermediate)Lesson 8: Sentence Architecture
Brazilian sentences often expand around direct objects, indirect complements, and predicative elements. Seeing these roles clearly makes longer clauses easier to read and produce.
Direct object = no preposition in the basic pattern
Many complements need a preposition
Predicatives describe the subject or object
Once you can distinguish objects, complements, and predicatives, the internal logic of the sentence becomes much clearer. That matters for pronouns, agreement, passive forms, and clause building.
verb + direct object / verb + prepositional complement / subject or object + predicative

A direct object normally answers "what?" or "whom?": "comprei o ingresso".
A prepositional complement depends on the verb, noun, or adjective: "gostar de música", "precisar de ajuda".
A subject predicative says what the subject is like or becomes: "o apartamento está vazio".
An object predicative says what someone calls, considers, or makes the object: "chamaram o menino de gênio".
Some verbs alternate between different complement patterns and change meaning slightly.
This lesson is about syntactic function, not just vocabulary choice.
| Portuguese | Meaning |
|---|---|
| Comprei o ingresso. | I bought the ticket. |
| Precisamos de ajuda. | We need help. |
| Ela gosta de música brasileira. | She likes Brazilian music. |
| O apartamento está vazio. | The apartment is empty. |
| Chamaram o menino de gênio. | They called the boy a genius. |
| Ela gosta de música. | She likes music. |
| O quarto está vazio. | The room is empty. |
| Chamaram João de gênio. | They called João a genius. |
A preposition does not automatically mean "indirect object"; it may be another kind of complement.
Some verbs allow more than one construction with different nuances.
