M'lord

M'lord, your word is my command.

1986, Ben Elton et al., Blackadder II, 3: "Money" There's a priest wants t'see you, m'lord. Well, tell him I'm Jewish.

2012, David Benioff et al., A Game of Thrones, 2.3: "A Man without Honor" And, girl. My lord. Lowborn girls say "m'lord", not "my lord". If you're going to pose as a commoner, you should do it properly.
