There are apparently some people who think they’re supposed to insert an apostrophe before ANY USE OF THE LETTER “S” AT THE END OF A WORD. Including a PROPER NOUN.
(And by “proper noun,” I mean someone’s NAME.)
You assume the error in question was at least attempting a possessive, right? No! It wasn’t even a possessive!
There is just no excuse for this. How much longer until someone writes out my last name as “Mier’s”? Come to think of it, I think it’s already happened, but then at least it was someone trying to use the possessive.
If you’re overwhelmed by the rules of apostrophe usage, here’s a handy rule of thumb: when in doubt, don’t use an apostrophe. It’s not error-free, but it’s a step in the right direction. Better to neglect than to abuse.
