Louis' party or Louis's party?

[goplayout]

Boy's name Louis, pronounced Loo-ee.

Any clever people around who know if it should be Louis' jacket or Louis's jacket? DS is quizzing me as to which is grammatically correct... I don't know

Louis's.

If it's pronounced Loo-ee and you don't add the final s, just the apostrophe, it would still be pronounced Loo-ee which would be wrong as a possessive - Loo-ee bag instead of Loo-ee's bag. So use the 's.
hth!

I personally always use 's, I would for example say James's coat, but AFAIK it is a matter of taste, ie James' coat is also correct.

It's harder to say tho if you want to indicate the apostrophe

As Louis' Louis's mum, that helps. But Louis's, does look wrong somehow.

Sorry, goplayout, I've interrupted your thread. I'm not your Louis's mum, btw.

Just checked Butcher's Copy-Editing, new edition: it says that New Hart's Rules say that if a name ends in an '-s' sound (James, Thomas) it takes an apostrophe s for possessive (James's, Thomas's) but if a name ends in a '-z' sound it doesn't (Moses', Jesus' Bridges').
hth?!

Oh thank you.

I will act all knowledgeable in the morning

What good taste you have sprouts!

The latter.

But I've seen the former used too.

au contraire...

The party of the boy named Louis.

Now I am confuddled. So is it Thomas' room. Thomas's room. Or Thomases room ? (as the woman making the sign suggested to me)

The second one.

But Saint Thomas' Hospital is is like that < and it is the hospital of Saint Thomas so can the room of Thomas not be Thomas'? I really should've worked this out before I called him that.

Seriously I NEED to know this.

I think you can use both but I prefer to use s's.

Louis's party, James' coat, Thomas' room.

Thank you so much. xxxxxx
The woman who was making up his door thingy said it should be THOMASES ROOM. I know that wasn't right. Why would you put a spare E there FFS?
