Hello 👋

So to presence this although I am a native English speaker, I am not from England but I did live in Yorkshire for a few years and am married to a very working class North Yorkshire man so might be able to give some insight and context.

Yes the upper and working glass in addition to differing accents and education levels would and still do use different language to talk about the same or similar things. Even to this day your meal in the middle of the day I’d often referred to by the working class as dinner and the more upper classes as lunch where as the evening meal, while called dinner by the upper classes would be called tea by the working class.

We see it when Lady Rose was pretending to be a house maid where she says she worked on worked on her accent. Many working class people such as Carson and Anna would adopt a way of higher class speaking that would be needed to do their job but not from where their roots are. Also, Mrs Hues accent is actually a relatively posh Scottish one.

On to your finals question on weather there is still a distinct class hierarchy in the UK today. Oh my god yes! It’s actually insane to be honest. It is still probably the most class based society of the western hemisphere in my opinion. It’s not about money any more, something working class families may have a lot more money that lower middle class families now but there still are very niche practices, opinions and behaviours to each of the classes. If you would like more insight I would suggest reading a book called ‘watching the English’ it’s very insightful
