Case

Grammatical case pertains to nouns and pronouns. A noun’s or a pronoun’s case shows its relationship with the other words in a sentence. A noun does not change its form in any of the cases other than the possessive case. A pronoun, however, changes its form in the possessive and the objective case.
The main cases you will encounter in English are:

 CaseExample

4Vocative Case (is addressed directly)Rina, is this your pen? Brother, could I take your pen?  Good bye, mother. You, get off my lawn. Go there, Rahim. May I come in sir.
