* Nominative Case: This refers to the form of a noun or pronoun that is the subject of a verb. It's the "doer" of the action. For example, in "The cat chased the mouse," "cat" is in the nominative case.
* Object Case: This refers to the form of a noun or pronoun that receives the action of a verb. It's the "receiver" of the action. For example, in "The cat chased the mouse," "mouse" is in the object case.
* Possessive Case: This refers to the form of a noun or pronoun that shows ownership or possession. It's indicated by an apostrophe and an "s" (e.g., "the cat's tail").
Why There's No "Nominative Object"
The terms "nominative" and "object" are essentially opposites. A nominative noun is the subject, while an object noun is the direct or indirect receiver of the action. They can't be both at the same time.
What You Might Be Thinking Of
Perhaps you're asking about:
* Direct Object: The noun or pronoun that directly receives the action of the verb. Example: "The cat chased the mouse."
* Indirect Object: The noun or pronoun that indirectly receives the action of the verb, usually specifying to whom or for whom something is done. Example: "She gave him a gift."
In Summary
There's no "nominative object" in traditional grammar. The concept of "nominative" refers to the subject of a verb, while "object" refers to the receiver of the verb's action.
