Possessive of a word that's already possessive?
There’s a bar near me named O’Leary’s Irish Pub—or just O’Leary’s for short. One day, they changed their menu. I wrote to a friend:
“O’Leary’s has changed their menu. O’Leary’s’s menu no longer has beer-battered onion rings.”
Is this usage correct?
I always use “ ’s ” to denote singular possessive—Charles’s office, Russ’s phone, Lars’s car, Baggins’s sword—so O’Leary’s’s seems completely natural to me. But several of my friends say it is wrong. Why?
The way I see it, it’s like this: Finnegan O’Leary works hard at O’Leary’s Irish Pub. The O’Learys are a friendly family. The O’Learys’ house is on Beacon Street. O’Leary’s’s menu is new. Many O’Leary’s’ doors have closed (meaning: the doors of many places named O’Leary’s over the years have closed).
p.s.—What about “My Night at Maud’s’s plot”?
