What is the form of a pronoun which changes to show relationship other words in sentence?

The form of a pronoun that changes to show its relationship to other words in a sentence is called case.

There are three main cases for pronouns in English:

* Nominative Case: Used for the subject of a verb or for a predicate nominative (a noun or pronoun that follows a linking verb and renames the subject). Examples: *I*, *you*, *he*, *she*, *it*, *we*, *they*.

* Objective Case: Used for the object of a verb or preposition. Examples: *me*, *you*, *him*, *her*, *it*, *us*, *them*.

* Possessive Case: Used to show ownership or possession. Examples: *my*, *your*, *his*, *her*, *its*, *our*, *their*.

Here are some examples of how pronouns change their case in sentences:

* Nominative: *She* went to the store. (subject)

* Objective: The dog chased *her*. (object of the verb)

* Possessive: *Her* car is blue. (shows possession)
