What Does “Thomas’s or Thomas'” Mean?
Before diving into specific rules, let’s clarify what we’re talking about. The forms Thomas’s and Thomas’ are used to indicate possession, meaning something belongs to Thomas. For example:
- “This is Thomas’s jacket.”
- “I borrowed Thomas’ pen.”
Both forms show ownership, but the rules for when to use each can vary depending on the style guide (e.g., APA, Chicago, or AP Style). Knowing when to use these forms and their alternatives is essential for proper communication.
Singular Possessive: Thomas’s
The singular possessive form Thomas’s is used when referring to something that belongs to one person named Thomas. This form is widely accepted and considered standard in most writing styles.
Rules for Using “Thomas’s”

Examples of Thomas’s in Use:

This form emphasizes ownership by one individual and is commonly used in both casual and formal writing.
Plural Possessive: Thomases’
