What does it mean to be "posh" these days?

speaking standard English for a start...

That would be one factor but fewer and fewer people speak with RP these days.

Received pronunciation, darling.

ahhhh yes but it can be because of their dialect and accent too

Not everyone who is well-spoken thinks of themselves as posh.
But if so-called posh people are frequenting the same places as common folk there is not much else to set them apart. That being said I've always thought "poshness" should be more about manners and good etiquette as it is about money.

I think the same but in this generation standards are loosening, even if you say 'whom' you are considered posh in my experience

LOL. I guess I would qualify then...

Perhaps they just mean old-fashioned...

perhaps my friend

I would say so, darling.

One would have to say, what a marvelous post!

I've recently been reading a few articles about how genuinely "posh" people are shunning Waitrose and shopping at Aldi, flying budget airlines, shopping at Primark, sending their kids to state schools, eating home-made food etc. etc. Generally doing everything on the cheap.

So the question is: why are these people "posh"? Why are such people still defined as posh and if it's just because of their background, would their children still be considered posh?

Market researchers use other key 'markers' to define posh target groups.

I say, rather. Jolly good show and all that. What ho.
