B1Lesson 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
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.

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.
