I see your point SilverBaubles, but I think it is over-stating the case to say that very often it is using a fancy French alternative to a solid English word. Why is 'mirror' fancy compared to the far more unwieldy 'looking glass'. What is the inherent difference between the words sofa and settee - they are both two syllable words beginning with S. How on earth is toilet a fancy word compared to the multi-syllable lav-a-tor-y. I agree that people often see pardon as a more delicate word than what. But I don't think it's quite the same as the people who constantly say, for example, myself instead of me because they think it sounds posh - since it is actually a grammatically correct useage.
More generally to the discussion. At what stage does a word become an ok word? Because, as everyone has agreed, there isn't really such a thing as an English word. It seems to me that a certain strata of society have a strong snobbish-ness towards French words.
Correcting other people's children is rude. In fact, correcting anyone's language is rather rude. But people who say 'pardon' themselves tend to do so because they were taught that 'what' is rude, so they are trying to observe polite social manners.
I think that's a more wholesome and honest aspiration than those who delight in sniggering that pardon is such a common word, and aren't those who use it just frightful. Isn't it all just even worse than cunt, ha ha.
And I would go further than SilverBaubles and say that I think that there is something particularly vile and spiteful in the English habit of laughing at anyone who tries to 'better themelves' by using posh language, but getting it wrong. I mean, how dare those lower class oiks try and sound all educated. And, snigger, they think serviette is a posh word. Snigger.
Dear god, I bought my own furniture. My parents say lounge (although I say living room, not sure why). How dare I say 'napkin' and 'sofa' and pretend I am better than I am. Don't worry, you'll catch me out when I ask to use your toilet and I try out my new perfume.
