This question often confuses writers when dealing with possessive nouns that end in “s.” Some style guides, like The Chicago Manual of Style, recommend adding apostrophe + s (Dennis’s) for clarity, while others, like AP Style, allow just an apostrophe (Dennis’) to keep it simple. The choice depends on grammar rules, pronunciation, and writing style.
This article will provide a side-by-side comparison, everyday usage examples, and possessive case rules to help you use the correct form. By understanding these grammar rules, you can write with confidence and accuracy. Let’s dive into the details and clear up the confusion.
Quick Summary
The possessive form of Dennis follows different rules based on writing style guides:
- Chicago Manual of Style (CMS): Always add ‘s for singular possessives (Dennis’s).
- AP Stylebook: Drop the s after the apostrophe to avoid excessive “s” sounds (Dennis’).
- American English Preference: Dennis’s is more common in formal writing.
- British English Preference: Dennis’ is often used to avoid extra syllables.

What is a Possessive Form? A Simple Overview
A possessive form in English grammar shows ownership or a relationship between a noun and another noun. Typically, you add an apostrophe followed by an “s” to indicate that something belongs to someone.
For Example, “the dog’s leash” means the leash belongs to the dog. This possessive form is crucial for understanding how objects, people, or concepts are connected to one another.
Possessives can be singular or plural. Singular possessives refer to one item or person, while plural possessives involve more than one. The placement of the apostrophe in these forms is essential for clarity and correctness. However, rules for possessives can get complicated when names or nouns end in “s,” leading to confusion over whether to use “Dennis’s” or “Dennis’.”
Dennis’s or Dennis’: The Controversy Explained
The debate between “Dennis’s”or “Dennis’” has caused confusion for many writers. Both forms are considered acceptable in English grammar, but they follow different rules depending on the style guide you use. Historically, English grammar suggested adding an apostrophe and an “s” for all singular possessives. However, this changed with the development of style guides like the AP Stylebook and the Chicago Manual of Style.
- AP Style (Journalistic Writing): Prefers “Dennis’.”
- Chicago Manual of Style (Academic & Formal Writing): Prefers “Dennis’s.”
- American vs. British English: American English favors “Dennis’s,” while British English prefers “Dennis’.”
