Not sure how to form the possessive of kids? Not sure if the apostrophe goes before or after the S? Do what the writer for Yahoo! Style did and hedge your bets: Put the apostrophe before and after it:
Thanks to the Yahoo! Style writers, we now have an opportunity to fill in the missing word in an online version of Mad Libs;
Is the missing word butt: Thanks to the Kardashian’s butt? Hard to tell since we don’t know which Kardashian this caption refers to. You’d think it would refer to all Kardashians, wouldn’t you?
I guess elementary schools don’t teach the same things nowadays that they did when I was a youngster. Of course, that was many, many decades ago, but I thought there were some subjects that were eternal. Like how to form the plural of nouns. Judging from this excerpt from Yahoo! Style, schools are neglecting that bit of knowledge — or the writer was playing hooky that day:
The possessive plural of lady is ladies’. It follows a simple rule: Form the plural of the noun and if it ends in S, add an apostrophe. So, it’s idiots’ and dummies’. If the plural doesn’t end in S, add an apostrophe and S: So women’s, children’s, and alumni’s are correct.
Someday the writers and editors at Yahoo! Style might actually display some knowledge of English grammar. This is not that day:
The plural of a name that doesn’t end in S is just the name with an added S, like this: the Clintons, the Obamas. (Adding an apostrophe makes the name a possessive, not a plural.) If the name ends in S, make it plural by adding an ES. But under no circumstances does the plural involve an apostrophe. Unless you’re writing about Mr. and Mrs. Apostrophe; then they’re the Apostrophes.
Hillary Clinton is the Democratic nominee for the presidency, but you wouldn’t know it if you read this on Yahoo! Style:
As a common noun, democratic refers to a democracy or people in general. But if you’re referring to the political party in the U.S., it’s Democratic, with a big D.
Speaking of a big D, that’s the grade I’d give this writer for coming up with Clintons’s. I’d be appalled if I hadn’t seen that error so often on Yahoo!. It seems Yahoo! writers (and their editors, if they have them) don’t know that the plural of Clinton is Clintons and the possessive of Clintons is Clintons‘.
