I got this newsletter from Jane Straus this morning in my inbox. Most of the time, I don’t forward these missives on to my blog, but this proves extremely helpful for people who have questions.
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.
puppy / puppies
army / armies
supply / supplies
However, proper nouns are not made plural in the same way common nouns are.
Rule: Do not change the spelling of a name to make it plural. Instead, just add s.
I visited the Murphys last weekend.
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.
I petted the Murphys’ cat.
I visited the Murphys’ store on Main Street.
Rule: To show the plural of a name that ends in s, ch, or z, add es.
