Understanding the differences between “classmate’s,” “classmates’,” and “classmates” is vital for clear communication. “Classmate’s” indicates possession by a single classmate, while “classmates'” shows ownership by multiple classmates. In contrast, “classmates” simply refers to more than one classmate without implying possession. Mastering these distinctions will enhance your grammar skills. In this guide, we’ll explore each term with examples to help you use them correctly in your writing.
Have you ever paused while writing about your fellow students, wondering whether to use classmate’s, classmates’, or just plain classmates? You’re not alone. This common grammar question trips up many writers, but I’ll break it down with clear examples and practical scenarios.
The Basic Rules of Possessive Forms
Let’s start with the fundamentals. The way we show possession in English follows specific grammar rules that vary depending on whether we’re dealing with a singular form or plural form.
Singular Possessive (Classmate’s)
When showing ownership for just one person, we use the singular possessive case. Simply add ‘s to the singular noun. For example:
- “My classmate’s notebook fell off the desk” (referring to one student’s property)
- “I really liked my classmate’s idea for the science fair” (one student’s suggestion)
- “The classmate’s item was left in the classroom” (belonging to a single student)
Plural Possessive (Classmates’)
When dealing with possessive nouns in their plural form, we add an apostrophe after the s. This plural rule applies when multiple people own something. Here are some examples:
- “The classmates’ project won first prize” (a project owned by multiple students)
- “I attended my classmates’ reunion last weekend” (a reunion for multiple former students)
- “The classmates’ meeting ran longer than expected” (a meeting involving multiple students)
Plain Plural (Classmates)
Sometimes you just need the plural noun without showing possession. In this case, simply add s without any apostrophe. For example:
- “Ten classmates joined the study group” (just counting students)
- “The classmates organized a surprise party” (describing what students did)
- “All my classmates passed the exam” (referring to multiple students)

Individual Student Scenarios
In cases of individual academic possession:
- “I borrowed my classmate’s notebook to catch up on notes” (one student’s notebook)
- “Sarah’s student book was left in the cafeteria” (belonging to one person)
- “The classmate suggestion changed our project’s direction” (one student’s input)

Common Mistakes to Avoid

When dealing with noun plurality and possession:
- Correct: “My classmate’s book” (one student’s book)
- Correct: “My classmates’ books” (books belonging to multiple students)
- Incorrect: “My classmates’s books” (incorrect formation)
