[HPFGU-OTChatter] What's "Cor" mean

[Sharon Hayes]

Mike:
I'm reading Lori Summer's second Paradigm of Uncertainty
installment. She uses "Cor" as some kind of exclamation for
her characters (well, JKR's characters mostly, with a few
of her own added). What I want to know is what does it mean?
Is it an elation, disgust, or what kind of utterance? And
does anybody know if it derives from some word, like... I
don't know... "correct" or something.

Sharon:
it means "Wow", something that is really good and unexpected. I'm not sure of the derivation but I had always thought it was one of those expressions that didn't really start out as a word but is written as "Cor". Similar to "Ugh" I suppose.  However if anyone DOES know its derivation (Carol??) I love to know as well.

Mike:
By the by, is it used any more, or was it in vogue for a
while and then fell out of vogue? (I've only read PoU, and
parts of Cassie Clare's "Draco Dormiens", as far as fanfic
goes. I just can't get into it.)

Sharon:
I believe it's still in use in the UK, but don't wuote me on that!
