English grammar can sometimes be tricky, especially when it comes to possessive forms. One common question that arises is whether phrases like “and I’s” are grammatically correct.

In this post, we’ll dive deep into possessive pronouns and their correct usage, clear up common misconceptions, and offer practical tips to master possessives.

Understanding Possessive Pronouns

Possessive pronouns are words that indicate ownership. They help us express relationships and show who something belongs to. Here’s a quick rundown of the most common possessive pronouns:

• My – for first-person singular (e.g., my book)
• Your – for second-person singular and plural (e.g., your car)
• His – for third-person singular masculine (e.g., his house)
• Her – for third-person singular feminine (e.g., her jacket)
• Its – for third-person singular neuter (e.g., its color)
• Our – for first-person plural (e.g., our garden)
• Their – for third-person plural (e.g., their project)

Example Sentences:

• My cat is very playful.
• Is that your pen?
• His opinion matters to me.
• Her shoes are on the porch.
• The cat licked its paw.
• We are excited about our vacation.
• Their answers were all correct.

The Grammar Behind “I’s” and Its Misuse

The term “I’s” is grammatically incorrect. In English, possessive forms are created using the apostrophe and ‘s’ (e.g., John’s book, the dog’s collar). However, “I” is a personal pronoun, and it doesn’t follow the same rules as nouns.

Why “I’s” is Incorrect

1. No Possessive Form for “I”: The pronoun “I” doesn’t form a possessive by adding an apostrophe and ‘s’. Instead, we use “my” to show possession.
2. Misunderstanding Possessive Constructions: People sometimes mistakenly apply possessive rules for nouns to pronouns, which is why you might see “I’s” used incorrectly.

Incorrect Example:

• My wife and I’s car (Incorrect)

Correct Example:

• My wife’s and my car (Correct)
• The car belonging to my wife and me (Correct)

Joint Possession with Pronouns

When expressing joint ownership, it’s crucial to use the correct grammatical structure. Joint possession means that two or more people share ownership of something. Here’s how to express it correctly:

The Right Way to Express Joint Ownership

Incorrect Example:

• My wife and I’s car (Incorrect usage of “I’s”)

Correct Examples:

• My wife’s and my car: This is grammatically correct and clearly shows that both you and your wife own the car together.
• The car of my wife and me: This alternative also works, though it’s less common in casual speech.

Why “My Wife and I’s Car” is Incorrect

1. Incorrect Possessive Form: Using “I’s” is incorrect because “I” doesn’t use an apostrophe to show possession.
2. Confusing Possessive Forms: Mixing possessive forms with pronouns and nouns can lead to confusion.

Correct Structures for Joint Possession

When it comes to joint possession, clarity and correctness are key. Here’s how to use possessives properly:

Proper Structures for Joint Possession

Correct Examples:

• My wife’s and my car: This structure is straightforward and grammatically sound. It clearly shows shared ownership.
• The car belonging to my wife and me: This is another correct way to phrase it, particularly useful in more formal contexts.

Common Mistakes and How to Avoid Them

Common Errors:

• Mixing possessive pronouns and nouns incorrectly: For example, saying “He and I’s book” instead of “The book of he and me.”
• Using incorrect possessive forms with pronouns: Using “I’s” or “he’s” incorrectly.

Tips for Avoiding Mistakes:

1. Double-check Possessives: Ensure you’re using “my,” “your,” “his,” “her,” “its,” “our,” or “their” instead of “I’s.”
2. Practice with Examples: Write out sentences using different possessive forms to reinforce correct usage.

Specific Cases: “He and I’s” vs. “He and My”

Comparing these two phrases highlights common mistakes in possessive grammar. Let’s break down why one is correct and the other is not.

“He and I’s” vs. “He and My”

Incorrect Example:

• He and I’s book (Incorrect, as “I’s” is not a proper possessive form)

Correct Examples:

• His and my book: This is grammatically correct and clearly shows joint possession.
• The book belonging to he and me: Though less common in informal speech, this is correct and clear.

Issues with Mixing Third Person and First Person Possessives

Mixing third-person possessives (e.g., his, her) with first-person possessives (e.g., my, our) can create confusion. Ensure you maintain grammatical consistency when combining these forms.

Example:

• His and my project (Correct usage)
• He and my project (Incorrect, should be “He and I’s project” but properly phrased as “His and my project”)
