It doesn’t matter if your audience doesn’t know what a gadrooned platter is. Often people are flattered to have an unusual word thrust upon them. They say, Well, that author thinks I know what he’s talking about! This is one of those rare sentences that changes the way my mind works. When I read a weird word in a magazine piece, I usually think the author is being pretentious or needlessly flowery - perhaps even a secret handshake inside a literary class where I don't belong. It never occurred to me to think this was showing respect to the reader.
