M'lord - Tumblr Posts
I’d say the usual mix of language happens here. When you are around people with different languages, dialects or wording you are going to adapt to it.
So Edd is highborn, but spends most of his time with the lowborn part of the NW, and most of the NW in general are lowborn, so he picked M’Lord up from them.
Satins background might have led to him spending time around highborn costumers either with him or the other prostitutes, thus learning the right use of my lord in the first place in order to please them (more money?).
With Quorin, Iron Emmet and Clydas it seem like Edd, they adapted the speech patterns from those around them. both Quorin and Iron Emmet being highly regarded through fighting and therefore spending more time with highborn members of the NW, since those are usually the better fighters due to training since childhood.
And similar to that Clydas would have taken his speech patterns through spending time with Aemond, especially since he was reading the letters for Aemond proper pronounciation would have come up.
That being said: I have no clue why Grenn uses My Lord, secret backstory we need to unlock maybe?
thinking about the use of “my lord” versus “m’lord” at the wall is actually pretty interesting because it’s kinda REALLY inconsistent but it also feels like, intentional. it’s weird that edd uses m’lord despite being highborn but he actually does use both interchangeably. despite being lowborn, satin grenn qhorin iron emmett and clydas all use my lord. a couple other characters appear to use both. what the hale does it mean
