Ross’s or Ross’?

The term Ross’s is the more common way to form the singular possessive of Ross. E.g., “Ross’s office is well-organized.” However, the word Ross’ without an additional “s” at the end is also correct, and it is a matter of preference which you use. E.g., “Ross’ presentation was impressive.”

The following table shows the singular forms of the name Ross.

Form	Example
Singular	Ross
Singular possessive	Ross’s/ Ross’

As you can see, you can form the singular possessive in two ways because the word Ross ends with an “s.”

According to Google Ngram, the more common possessive form is Ross’s. This is also the form you should follow for APA Style and Chicago Manual of Style.

Alternatively, you can use the less popular version, which is Ross’. You should use this version with no additional “s” if you follow AP Style.

Considering the above rules, both of the following sentences are correct:

• Ross’s dog is friendly.
• Ross’ project received positive feedback.

However, if you start using one version in a text, you should continue with that version until the end.

Although, whichever version you choose to use, you must be consistent and use the same version throughout the text.

Ross’

The term Ross’ with an apostrophe and no additional “s” is a singular possessive form of the name Ross.

However, it has never been as popular as Ross’s with an “s,” although Ross’ is the correct version if you use AP Style.

Also, if you choose to use the version without the second “s,” you should use that version throughout the document, regardless of whether the following word starts with “s.”
