Ordering a sign for my son James. Its going to say Games Room. Lots of arguing about the apostrophe. Should it be James' Games Room or James's Games Room?
From the punctuation guide:
The possessive of a plural noun is formed by adding only an apostrophe when the noun ends in s, and by adding both an apostrophe and s when it ends in a letter other than s.
Theres no set rule for James though-say as St Thomas's /St Thomas' , and there are schools called St James's and St James'.
Better to put James's as thats what you'd say IMO but we do say Jesus' rathe rthan Jesus's so as it's christmas.....
If your worried about visitors think you've got it wrong then putting something else like Games Room. James. or call him Jim!
James' is the current preferred option, although I prefer James's. I attended St James's School as a boy (it's carved into the stone on the building). I now notice that the painted board at the entrance has St James' School.
Technically, James' implies there is more than one Jame and the room belongs to them all. But I do accept it looks better than the s's termination.
There is an argument that says James is the name of the room (like Games) and requires no apostrophe - this option often used in street names, etc. (e.g. Albert Square, George Street)
