> I was always taught it was 'Master' for unmarried and young men.
I remember when I was a kid, bank correspondence would address me as MASTER. I found it amusing.
I don’t think they do that anymore though??? I think our son has always been MR to them, even when he was a 5 year old
Which country? Never heard of it in the US but feels like a commonwealth or UK thing?
I knew someone with the surname Bates, that was amusing when things like his bank sent him letters when he was under 18.
I see it used a ton in an airline context.
I'm in the UK. Letters from healthcare providers regarding my minor son is addressed as "Master <name>".
