How exactly can you tell if somebody is really, truly posh?
Some would say it's all to do with social circle. If their friends include minor Royals, say, or they went to school with Bear Grylls, then they are posh. Some would point to clothes and style, saying that items like red trousers and signet rings give the game away.
Others, though – and this includes many experts – say it's all in the chat. This month society magazine Tatler has drawn up a list of words that instantly denote poshness, in fact. From 'beastly' to 'yonks' and 'shriek' to 'ravishing', the most idiosyncratically posh words are shamed at last.
It's an illuminating read, and certainly not just a random collection of words hastily cobbled together on press day at Tatler Towers (though even if it was, they are the experts).
