I realize that the proper use of " 's " and " ' " when using the possessive case with nouns that end in S has been something previously discussed on this forum. I came across several topics on the subject already in my search for a few answers. It seems as though it has generally been agreed upon that it is equally acceptable to write either " Gladys' " or " Gladys's " when referring to something owned by Gladys. I did not however come across a topic directly pertaining to my case. I happen to be named Ross, and I was wondering if the either or rule works for my name as well. in school I found that most of my English teachers were inclined to tell me that simply " Ross' " was the correct way to write it. Which brings me to the second part of my question. I vaguely remember that one of the English teachers that I asked replied by saying that both were possible spellings, but that, in the earlier history of the language, adding " 's " on to the end of a proper noun that already ended with " ss " was only used with royalty or gods. So my question is twofold: 1) How do I label something as mine? And 2) Do I need to worry about committing an act of hubris in the attempt? Thanks in advance for your consideration.
