Useful “How To Use An Apostrophe” flowchart from The Oatmeal:
@john personna: I still fight against that, but I’m losing.
James and John Personna: That’s an uphill battle against going-on 500 years of English usage. See: Court of St. James’s or St. James’s Place (1535)
Regarding possessives of words that end with “s”, I wrote on the subject a while back when Arkansas designated its official possessive spelling as Arkansas’s. I consulted five universities, all of which had different opinions.
I was taught never to put the “‘s” in there, until around high school when it was deemed acceptable. My wife was taught that you add apostrophe-s when it’s in the pronunciation. So it would be James’ and Arkansas’s (since you’re pronouncing an “s” where you otherwise wouldn’t for the latter), and that the pronunciation for James’ is actually the same as James, not Jameses.
According to Merideth College, the rules that govern S also govern X and Z, so it would be Alex’ or Alvarez’ instead of Alex’s or Alvarez’s, but I have never seen that in practice.
If Strunk and White sayeth that an apostrophe +s shall be used to denote ownership when using a proper name, regardless of consonant ending of said name, with the exception of “Jesus” (but only that one Jesus, not some guy from Latin America), then it shall be so.
Now, I wonder what they have to say about needlessly long and confusing sentence clauses…
Also, this song has always been useful (just after the email is read):
@Neil Hudelson: Neil you beat me to it. That was what I was going to post… and I do still sing that song at times when working through proofreading.
