Dennis’ or Dennis’s? A Simple Guide to Possessive Forms

By Mariah Cannon

Understanding the difference between Dennis’ and Dennis’s can be a bit tricky, but don’t worry! In this article, we’ll walk you through everything you need to know using simple examples and explanations, perfect for anyone who wants to grasp the rules easily—like if you’re just starting to learn about possessive forms.

Let’s dive right in, starting with what possessives are and then focusing on the singular and plural possessive forms.

What Are Possessives?

Possessive forms show that something belongs to someone or something. You can recognize a possessive form by the apostrophe ('), often followed by an s.

For example:

  • Dennis’s book means that the book belongs to Dennis.
  • Dennis’ book can also be used by some, particularly when a name ends with an s.

There are different rules depending on whether we’re talking about singular possessive, plural possessive, or just making something plural.

Now, let’s break it down!

The Singular Possessive: Dennis’ or Dennis’s?

When a name ends in s, it’s common to see both forms, but some people follow specific grammar rules. There is some flexibility here, so let’s explore both.

Dennis’ (No extra s)

  • In many cases, the possessive of a name ending in s can just have an apostrophe (‘) without adding another s.Example: Dennis’ shoes – This means the shoes belong to Dennis.This style is widely accepted and is especially common in newspaper writing or more formal writing.

Dennis’s (Adding the s)

  • Some people (and style guides) prefer to add an s after the apostrophe when making a name possessive.Example: Dennis’s car – This means the car belongs to Dennis.Both forms are technically correct, so you can choose the one you prefer or follow the style guide you’re using.

The Plural Possessive: When You Have More Than One Dennis

Next, let’s consider when you want to show possession for more than one Dennis. The rule changes slightly for plural possessives.

Plural Possessive Form

  1. If you have more than one Dennis (Denni?), you first make the name plural. This is done by adding s.Example: Dennis becomes Dennises for more than one Dennis.
  2. Now that we have the plural form, we make it possessive by adding an apostrophe.So, it becomes Dennises’.Example: The Dennises’ house means the house belongs to more than one Dennis.

Here’s a quick breakdown in a table format for easier understanding:

FormExampleMeaning
Singular PossessiveDennis’ book or Dennis’s bookThe book belongs to Dennis
Plural FormDennisesMore than one person named Dennis
Plural PossessiveDennises’ houseThe house belongs to more than one Dennis

What Should You Use?

  • Dennis’s or Dennis’? It depends on the style guide or your personal preference, but Dennis’s is often preferred when clarity is important (like in casual writing), while Dennis’ can sound more formal.
  • When it’s a plural form (like multiple people named Dennis), remember to make the name plural first (Dennises) and then add the apostrophe for possession (Dennises’).

A Quick Tip for Better Writing

When you’re unsure, think about how the word sounds. If you would naturally add an s sound at the end, then add it after the apostrophe for clarity and flow. If it feels better without the s, just stick with the apostrophe.

Conclusion

To sum up:

  • Dennis’ or Dennis’s: Both are acceptable, but the choice depends on personal or formal style preference.
  • Dennises’ is for plural possession when there are multiple people named Dennis.
