Americans can never get titles right because we don’t have them here and we are unfamiliar with how they work.
But it’s like spelling. If you don’t know, look it up.
I'm weird about grammar--get my teeth on edge at: "Everybody has a right to their opinion" and "Could you have dinner with my wife and I?"
But, it's kinda (sic) like music--or anything else--if you know the rules you know how to break 'em (sic again).
De Bussy was kicked out of the Paris Conservatory for breaking the rules of harmony etc. He was inventing new harmony etc. And Rachmaninov's harmony--breaking the rules--is gorgeous and innovative.
A few days ago, just for fun, I uttered: "Was someone calling I?" (You can just call me Claude-Sergei, thank you.)
So, if I refer to Princess Di as Princess Di, it's not that I don't know any better.
It's kinda like an Amercan referring to Her Majesty--I wouldn't do it, mind you!--as Cousin Lizzie. Maybe they just want to emphasize the close connection between the US and the UK.
See what I mean?
Good.
Now, would you explain it to me?
