This may seem like a silly subject to write about, but I must admit that I’ve
had trouble using the apostrophe appropriately in the past, especially regarding its use with proper nouns that end in “s”. I’ve written a similar blog in the past, but it’s become a personal dilemma since the main character in my debut novel is named Jon Masters and the book is going to be published soon. So I’ve spent considerable time editing and at times facing this issue.
How do I refer to Jon’s wife in my writing? Is she Jon Masters’ wife or is she Jon Masters’s wife? Well, I looked up the accepted method to depict such a possessive proper noun and my confusion worsened. The Associated Press Stylebook recommends using just an apostrophe after the name—in this case, Masters’. But other writing experts recommend adding the apostrophe PLUS an “s” after the name—as in Masters’s.
A noted e-newsletter on English grammar, called GrammarBook.com, devoted a blog to the subject and stated that the rule to be followed is this: “Forget the apostrophe until you write out the entire word. A correct possessive apostrophe can never entangle itself within any word.”
So if I used this rule from Jane Straus’s GrammarBook newsletter, then I could be assured that “Jon Masters’s wife” would be the correct way to write that phrase! But interestingly, my computer’s spell check underlines this spelling in red—indicating that I made an error. (Sigh!)
Does this mean that The Associated Press Stylebook is correct and a noted English grammar expert is wrong? Further research findings (noted here and here) give conflicting rules. One reference states that only an apostrophe is needed after a word that ends in “s” to show the possessive, while another states that an apostrophe PLUS an “s” is needed after a word already ending in “s” when writing a possessive noun. (More Sighs!!)
As I decide which is correct, another thought comes to mind. What is the proper way to write the possessive when the proper noun is plural—for instance, when referring to both Jon Masters and his wife, Gwen?
Well, the rules are quite clear when it comes to the plural of a
proper name ending with an “s”. The rule states that you always use an “es” after the “s”—in this case, I would refer to the married couple as the Masterses. That’s a mouthful to say the least, but it is correct.
And how would I write the possessive of that word? Would it be the Masterses’ house or the Masterses’s house? Again, when using the plural of a possessive proper noun ending in “s”, the rules are quite clear also. The rule states that one adds only an apostrophe after the existing “s” in a proper noun that is also plural and ends in “s”—in this case, Jon and Gwen’s house would be written as the Masterses’ house. Although correct, that phrasing does sound rather awkward. When all is said and done, I might circumvent this rule entirely and instead phrase it as “the house of Jon and Gwen Masters.” (Another Sigh, but this time with a Smile!)
While there are some discrepancies between The Associated Press guidelines and the Chicago Manual of Style, modern English literature seems to adhere to three specific guidelines for apostrophes with 
possessive proper nouns: If the noun is singular, add an apostrophe before the “s”—as in Jon’s. If the noun is singular but ends in “s”, also add an apostrophe before the “s”—as in Jon Masters’s. If the noun is plural and ends in “s”, just add an apostrophe—as in the Masteres’ house.
Although I have these rules firmly in command now and will apply them in the editing of my work, I’ll leave you with one disclaimer: these rules don’t necessarily apply to my friends across the pond, over our northern border, those Down Under or writers in other nations that use the English language as their written word.
My research tells me that I can only safely say that these rules seem to apply to writers within the borders of the United States who are writing for a domestic audience.
Thoughts? Comments? I’d love to hear them!

SPOILER ALERT:
My debut novel Lethal Medicine (with protagonist Jon Masters) will publish in less than two weeks. IT WILL HAVE NO POSSESSIVE NOUNS that require me to do any of the above apostrophe calisthenics regarding Jon Masters. (Sigh of Relief!)

Prescription For Murder 
Jim,
Another tangled web in English. Thanks for this. When I write something I expect anyone else to read, I always read it out loud, usually just internally. At least for me, the slowness of speaking speed finds a lot of awkward structures, missed words, or the wrong word. I tried reading your blog out loud — parts of it, while totally correct, sound strange. I get concerned that my audience will also find it strange, potentially taking their concentration away from my message.
I find that if I am writing something that will be spoken, like a presentation or speech, I write differently than when I am writing to be read, like my blog. I become more concerned about the sound, avoiding word combinations that are difficult to say or, worse, if not spoken clearly may have a different inference. If some of the listeners have limited English, then I find I use shorter, simpler words and avoid cliches like the plague. Cadence becomes important, as does leaving logical spaces to breathe. In a well written story, dialogue may sound different than the narrative.
Of course, you could have just changed his name to Jon Master.
Looking forward to reading Lethal Medicine.
Walt.
Yes, understood – speaking, writing narrative, dialogue – all requires different approaches.
BUT change Jon Masters to Jon Master?? Where’s the challenge in that and if I did that, I wouldn’t have had such wonderful subject matter for this very confusing blog. As you know, I always appreciate your comments and look forward to seeing you soon. All the best ~
Hmmm. Apostrophic calisthenics? 😉
There are (at least in UK English, and I believe in US English as well) some other exemptions for names of a traditional or classical nature – for example Jesus’ rather than Jesus’s, or Socrates’ rather than Socrates’s. A great get-out for those of us who write historical fiction but not so useful for those who write contemporary stuff!
Thanks, Richard – always looking for MORE exceptions to the rules (LOL) Truly, I appreciate all the help muddling thru apostrophes. I avoid them like the plague! All the best ~
