Sorry if I have just bounded in but if many of you are writers, I'm sure you have good words you like to use.
If I come across an unusual word or one I don't understand I love to find the meaning and then use it where I can.
Such as;
Coprolites or Coprolite (the spell check hasn't even heard of this one)
It's fossilized dinosaur er dung. It's got to be a good word to call someone in a cheery voice so they don't realise you are insulting them.
