Third Grade English: Grammar: Parts of Speech - Subject, Object, and Possessive Pronouns
Pronouns are indispensable substitute words that stand in place of nouns to keep our spoken and written language smooth, natural, and free from clumsy repetition. Without pronouns, sentences would sound ridiculously awkward, forcing you to say, "Marcus picked up Marcus's backpack because Marcus was late for Marcus's bus." By mastering the three primary case categories—Subject Pronouns that perform actions, Object Pronouns that receive actions, and Possessive Pronouns that show ownership—you will construct polished, sophisticated sentences throughout third grade.
The Purpose of Pronouns: What Is an Antecedent?
To understand how pronouns work, you must first meet the antecedent. An antecedent is the specific noun that the pronoun replaces.
+-------------------------------------------------------------+
| THE PRONOUN-ANTECEDENT PARTNERSHIP |
+-------------------------------------------------------------+
| |
| "Sophia forgot her jacket, so she ran back inside." |
| ^ ^ ^ |
| | | | |
| ANTECEDENT POSSESSIVE SUBJECT |
| (Noun) PRONOUN PRONOUN |
| |
+-------------------------------------------------------------+
Why Antecedents Matter
A pronoun has no meaning by itself. If you walk into a room and say, "He dropped it on them," nobody knows what you are talking about! The noun must be introduced first so the reader knows who "he", "it", and "them" represent.
Category 1: Subject Pronouns (The Actors)
A subject pronoun replaces a noun that serves as the subject of the sentence—the person or thing performing the main action.
+-------------------------------------------------------------+
| SUBJECT PRONOUN CHART |
+-------------------------------------------------------------+
| SINGULAR PLURAL |
+--------------------+-----------------+----------------------+
| 1st Person (Me) | I | We |
| 2nd Person (You) | You | You |
| 3rd Person (Others)| He, She, It | They |
+-------------------------------------------------------------+
Subject Pronoun Examples
- I finished my book report early.
- He plays the violin with great passion.
- She calculated the math problem accurately.
- They built a treehouse in the backyard.
- We are traveling to the Grand Canyon this summer.
Category 2: Object Pronouns (The Receivers)
An object pronoun replaces a noun that receives the action of a verb or follows a preposition (such as to, for, with, at, from).
+-------------------------------------------------------------+
| OBJECT PRONOUN CHART |
+-------------------------------------------------------------+
| SINGULAR PLURAL |
+--------------------+-----------------+----------------------+
| 1st Person (Me) | me | us |
| 2nd Person (You) | you | you |
| 3rd Person (Others)| him, her, it | them |
+-------------------------------------------------------------+
Direct Objects vs. Prepositional Objects
- Direct Object: The coach congratulated her. (Who did the coach congratulate? Her!).
- Prepositional Object: Grandma knitted a scarf for him. (Follows preposition "for").
- Prepositional Object: Come sit with us. (Follows preposition "with").
The Famous "I vs. Me" Mystery Solved!
One of the most frequent grammar mistakes among students is choosing between "I" and "me" when pairing a pronoun with a friend's name. Use the Drop-the-Friend Trick to solve this instantly every time!
+-------------------------------------------------------------+
| THE DROP-THE-FRIEND TRICK |
+-------------------------------------------------------------+
| Question: Should you say: |
| "Marcus and (I / me) walked to the park"? |
| |
| Test: Drop "Marcus and" out of the sentence temporarily: |
| - Would you say: "Me walked to the park"? NO! |
| - Would you say: "I walked to the park"? YES! |
| |
| Put Marcus back in: |
| -> "Marcus and I walked to the park." (Correct!) |
+-------------------------------------------------------------+
Testing Object Pronouns with the Same Trick
- Question: "Aunt Clara baked cookies for Marcus and (I / me)."
- Drop the friend: "Aunt Clara baked cookies for I" (Wrong!) vs. "Aunt Clara baked cookies for me" (Right!).
- Put Marcus back in: "Aunt Clara baked cookies for Marcus and me." (Correct!).
Category 3: Possessive Pronouns (The Owners)
Possessive pronouns show ownership without using any apostrophes!
+-------------------------------------------------------------+
| POSSESSIVE PRONOUN ROSTER |
+-------------------------------------------------------------+
| USED BEFORE NOUNS (Possessive Adjectives): |
| my, your, his, her, its, our, their |
| Example: "This is my jacket." |
| |
| STAND-ALONE POSSESSIVE PRONOUNS: |
| mine, yours, his, hers, ours, theirs |
| Example: "This jacket is mine." |
+-------------------------------------------------------------+
The Critical "Its vs. It's" Rule
Never put an apostrophe in the possessive pronoun "its"!
- its = possessive pronoun showing ownership ("The kitten licked its paws").
- it's = contraction meaning "it is" ("It's raining outside").
- Test: Replace the word with "it is". If "it is" makes sense, use "it's". If "it is" sounds ridiculous ("The kitten licked it is paws"), use "its"!
Practice Exercises and Pronoun Mastery
Put your pronoun skills into practice.
Exercise 1: Identify the Pronoun Type
Identify whether each underlined pronoun is a Subject, Object, or Possessive pronoun.
1. She gave a fascinating presentation on marine biology.
2. The teacher handed the assignment to him.
3. That shiny green bicycle on the rack is mine.
4. They invited us to the community barbecue.
Exercise 2: Choose the Correct Pronoun
Select the correct pronoun for each blank.

Answer Key and Explanations
- Exercise 1:
- "She" = Subject Pronoun (performs action).
- "him" = Object Pronoun (receives action after preposition to).
- "mine" = Possessive Pronoun (shows ownership).
- "They" = Subject Pronoun; "us" = Object Pronoun.
- Exercise 2:
- I ("I built", not "me built").
- her ("Called her", not "called she").
- its (Possessive showing ownership; no apostrophe!).
