English grammar is filled with complex rules, and even more complex exceptions to those rules. Elementary school children are taught the basics of the eight parts of speech, such as nouns and adjectives, and how to construct a complete sentence. However, even college graduates sometimes have a difficult time immediately recognizing and distinguishing between a nominative pronoun and an objective pronoun.

Pronoun Use

A pronoun is a word that takes the place of a noun or another pronoun. For example, instead of saying, "Holly finished her homework," you might replace the noun "Holly" with the pronoun "She," saying instead, "She finished her homework." Pronouns keep written and spoken language less repetitive: "Jim noticed the sink was still dripping when he turned it off," as opposed to "Jim noticed the sink was still dripping when he turned the sink off." Pronouns are not as specific as nouns. "It" can refer to any number of things. Care must be taken to use pronouns properly.

Nominative and Objective

In language, a nominative generally refers to the subject of a sentence, which is the performer of the verb in the sentence. For example, in the sentence, "The dog ran," "dog" is the nominative, because it's the performer of the verb "ran." An objective refers to a recipient or object of a verb or preposition. In the sentence, "Bill threw the ball," "ball" is an objective noun because it is the recipient of the verb "threw."

Nominative Pronouns

A nominative pronoun serves as the subject of a sentence or clause. For example, in the sentence, "Susan seems very tired today," "Susan" is a noun that is demonstrating the state of being tired. When "Susan" is replaced with the pronoun "she," then "she" becomes the subject of the sentence. Other examples of common nominative pronouns are "I," "he," "we," "they, "you" and "it.".

Objective Pronouns

While nominative pronouns demonstrate a state or action, objective pronouns are the objects of an action or preposition. If someone were asked, "Where are the cookies?" he might reply, "I ate them." In the latter sentence, "them" is the objective pronoun. It has taken the place of the noun "cookies" and is the object of the verb "ate." Someone on a date might explain to a waiter, "She is with me." In this sentence, "me" is the object of the preposition "with."

Pronoun Forms

The nominative and objective forms are usually specific to their use. "I," "he," "she," "we" and "they" are all examples of nominative pronouns because they can be used only in the nominative case. "Me," "him," "her," "us" and "them" are all objective forms. Other pronouns, such as "you" and "it," can be either nominative or objective.

Misuse and Confusion

Perhaps the most common problem with nominative and objective pronouns is mistaken usage. Though many say, "Tom and me watched a movie," the nominative pronoun "I" should be used instead: "Tom and I watched a movie." Hyper-correction can be a problem as well. Some use the nominative when it isn't called for: "The party is for my husband and I." The objective pronoun "me" is the correct object of the preposition "for."
