It's lovely.
Most archaisms are; that's often why we choose to use them.
UK mostly seems to mostly use 'has got' for possession
Here's a tip; if anyone's doing a Cambridge language exam, they may well get extra marks for (to be) + got, rather than have. To do with coherence and register.
''He owns a great deal of patience'. Is that usage found anywhere in the B-Isles?
No, not at all, though it's heard on Aussie soaps.
And when/where id 'different to' appear? I hate that one... just sounds wrong
Quite, though it's common. Of course "from" is correct however in Standard English, "than" has started to appear, probably due to Netflix, Hollywood etc.
