To Apostrophe or Not to Apostrophe: How to Pluralize Your Last Name

Let's suppose your last name is Jones, and you and your family want to send out holiday greeting cards or wedding invitations. How would you make your last name plural—Jones'? Jones's? Or Joneses?

Although it may seem complicated at first, the rules of pluralizing last names are actually pretty simple, as Slate has pointed out. Unless you want to make your last name possessive, there aren't any circumstances where you would need to add an apostrophe.

The rule goes like this: If your name ends in s, x, z, ch, or sh, add -es to the end. Walsh becomes Walshes, and Malkovich becomes Malkoviches. For all other endings, simply add -s to the end (as in Smiths, Whites, Johnsons, etc).

Of course, things get a little trickier when you want to make a last name plural and possessive. "Errors involving plural proper names are so common that I almost never see them written correctly," June Casagrande writes for the Los Angeles Times.

Let's say you want to notify friends and family that a party will be held at the Jones household. You could take the easy way out and write just that, or you could opt for, "The party will be held at the Joneses' house." Simply tack an apostrophe onto the end of a plural name to make it possessive. Plural first, then possessive.

The LA Times provided a few other examples of plural possessives:

"Unlike singular possessives, which take an apostrophe followed by an S, plural possessives take an apostrophe alone. So if you're going to the home of the Smiths, you're going to the Smiths' house. If you're going to visit the Williamses, that would be at the Williamses' house. Mr. and Mrs. Mendez, known collectively as the Mendezes, live in the Mendezes' house. And Mr. and Mrs. Berry, whom we call the Berrys, live in the Berrys' house."

On the other hand, if Mr. Jones lived alone and was having a party at his place, you would write "Mr. Jones' house" or "Mr. Jones's house." Both are acceptable—it's merely a difference of style and personal preference. Names that end in s are the exception to the singular possessive rule, though. You'd normally just add 's to make a singular name possessive, such as Mr. Berry's house or Mrs. Mendez's house.

Now that you know exactly when and where to add an apostrophe, your holiday greetings will not only be jolly but also grammatically correct.

Presidents Day vs. President's Day vs. Presidents' Day: Which One Is It?

Happy Presidents’ Day! Or is it President’s Day? Or Presidents Day? What you call the national holiday depends on where you are, who you’re honoring, and how you think we’re celebrating.

Saying "President’s Day" implies that the day belongs to a singular president, such as George Washington or Abraham Lincoln, whose birthdays are the basis for the holiday. On the other hand, referring to it as "Presidents’ Day" means that the day belongs to all of the presidents—that it’s their day collectively. Finally, calling the day "Presidents Day"—plural with no apostrophe—would indicate that we’re honoring all POTUSes past and present (yes, even Andrew Johnson), but that no one president actually owns the day.

You would think that in the 140 years since "Washington’s Birthday" was declared a holiday in 1879, someone would have officially declared a way to spell the day. But in fact, even the White House itself hasn’t chosen a single variation for its style guide. They spelled it “President’s Day” here and “Presidents’ Day” here.

Maybe that indecision comes from the fact that Presidents Day isn’t even a federal holiday. The federal holiday is technically still called “Washington’s Birthday,” and states can choose to call it whatever they want. Some states, like Iowa, don’t officially acknowledge the day at all. And the location of the punctuation mark is a moot point when individual states choose to call it something else entirely, like “George Washington’s Birthday and Daisy Gatson Bates Day” in Arkansas, or “Birthdays of George Washington and Thomas Jefferson” in Alabama. (Alabama loves to split birthday celebrations, by the way; the third Monday in January celebrates both Martin Luther King Jr. and Robert E. Lee.)

You can look to official grammar sources to declare the right way, but even they don’t agree. The AP Stylebook prefers “Presidents Day,” while Chicago Style uses “Presidents’ Day.”

The bottom line: There’s no rhyme or reason to any of it. Go with what feels right. And even then, if you’re in one of those states that has chosen to spell it “President’s Day”—Washington, for example—and you use one of the grammar book stylings instead, you’re still technically wrong.

Can You Tell an Author’s Identity By Looking at Punctuation Alone? A Study Just Found Out.

In 2016, neuroscientist Adam J Calhoun wondered what his favorite books would look like if he removed the words and left nothing but the punctuation. The result was a stunning—and surprisingly beautiful—visual stream of commas, question marks, semicolons, em-dashes, and periods.

Recently, Calhoun’s inquiry piqued the interest of researchers in the United Kingdom, who wondered if it was possible to identify an author from his or her punctuation alone.

For decades, linguists have been able to use the quirks of written texts to pinpoint the author. The process, called stylometric analysis or stylometry, has dozens of legal and academic applications, helping researchers authenticate anonymous works of literature and even nab criminals like the Unabomber. But it usually focuses on an author's word choices and grammar or the length of his or her sentences. Until now, punctuation has been largely ignored.

But according to a recent paper led by Alexandra N. M. Darmon of the Oxford Centre for Industrial and Applied Mathematics, an author’s use of punctuation can be extremely revealing. Darmon’s team assembled nearly 15,000 documents from 651 different authors and “de-worded” each text. “Is it possible to distinguish literary genres based on their punctuation sequences?” the researchers asked. “Do the punctuation styles of authors evolve over time?”

Apparently, yes. The researchers crafted mathematical formulas that could identify individual authors with 72 percent accuracy. Their ability to detect a specific genre—from horror to philosophy to detective fiction—was accurate more than half the time, clocking in at a 65 percent success rate.

The results, published on the preprint server SocArXiv, also revealed how punctuation style has evolved. The researchers found that “the use of quotation marks and periods has increased over time (at least in our [sample]) but that the use of commas has decreased over time. Less noticeably, the use of semicolons has also decreased over time.”

You probably don’t need to develop a powerful algorithm to figure that last bit out—you just have to crack open something by Dickens.
