Grammatical Cases in Portuguese

Casos gramaticais em português

Introduction Introdução
Cases describe the grammatical functions of nouns, pronouns and noun phrases, such as whether they are the subject of the clause or a subordinate object.
Nominative Case O caso nominativo
The nominative case, also called the subjective, marks the subject of a phrase. The subject is the noun (or pronoun) that performs the action of the verb. For example, in the phrase "She helped him", the subject is "she", who performs the action of helping.
Accusative Case O case acusativo
The accusative case deals with direct objects. In English for example, in the sentence "I drink coffee", the direct object is "coffee", and thus it is in the accusative case.

It is sometimes called the oblique case, especially when combined with the dative case.
Dative Case O caso dativo
The dative case marks indirect objects, which are usually used with a preposition. For example in the phrase "talk to him", the direct object is "him" because it is the thing to which the action is given.

It is sometimes called the oblique case too, especially when combined with the accusative case.
Disjunctive Case O caso disjuntivo
Sometimes called the prepositional case, the disjunctive case marks objects are being separated (or disjoined) from the verb usually by a preposition.

For example, in the phrase "bring it to me", the word "me" is in the disjunctive case.
Comitative Case O caso comitativo
The comitative case marks pronouns as going "with" the action of the phrase.
