Your honor, My lord, Your highness, My lady all refer to another person. What are the rules behind that?
The striked-out questions are answered by Why is it "your Majesty", but "my Lord"? . Thank you guys!
Why do we use "Your" while sometimes use "My"?
First, let's say, Tom is my friend. I would say "My friend, would you like a coffee?" It would be weird if I say "Your friend, would you like a coffee?"
Why don't we use "Your friend" like "Your honor"?
Second, I feel it looks like Apposition if I interpret "Your honor" as "You, honor". Why do we use the possessive form?
Third, say I'm a loser. I would like to coin an honorable form for other people to call me. Which is more correct, "Your loser" or "My loser"?
I'm particularly interested in the usage in the United States if there's any difference.
