Plural and Possessive Forms with Names Ending in y

How do you form the plural of a proper noun that ends in y such as Murphy? Should you change the name to Murphies? Given how other English words ending in y form their plurals, you would think so.

Examples:
puppy / puppies
army / armies
supply / supplies

However, proper nouns are not pluralized the same way as common nouns are.

Rule: Do not change the spelling of a name to make it plural. Instead, just add s.

Example: I visited the Murphys last weekend.

Example: We have two Zacharys in our office.

What if you want to show possession with a name that ends in y?

Rule: To show singular possession, use the apostrophe and then the s.

Example: I petted Mrs. Murphy’s cat.

Rule: To show plural possession, make the proper noun plural first, then use the apostrophe.

Example: I petted the Murphys’ cat.

Example:

Rule: To show the plural of a name that ends in s, ch, or z, add es.

Examples:
The Sanchezes will be over soon. The Thomases moved away.

    Rules on “first annual”…..

  4. Jane says:

    I know that some sticklers say that “first” is redundant in “first annual,” but I don’t agree. I think “first annual” is fine because it tells readers what they can expect in the future.

  5. Dana says:

    What if the last name ends in an i as in ..ski? Would it be ..skis or ..skies?

  6. joann says:

    the last name James: the tickets are Mike Jameses?

    • Jane says:

      Since you are talking about tickets belonging to Mike James, an apostrophe is used to show possession. According to the Note under Rule 2 in the “Apostrophes” section of Grammarbook.com, “Although names ending in s or an s sound are not required to have the second s added in possessive form, it is preferred.” Therefore, Mike James’s tickets would be the preferred spelling.
