Deipnosophist n. Someone skilled at across-the-table chit chat
According to Michael Quinion, the Greek term deipnon means "dinner" and, of course, sophist means "a master of his craft." So where does "chit chat" come from? Shouldn't deipnosophist simply refer to a superior eater? Why, just earlier today I was eating and doing quite a splendid job of it when it occurred to me that I was actually no deipnosophist, just a good eater.
Take a guess before you google it to see how many times the word does occur out there - but most of the occurrences are not in a context of communication but in gawking definitions. I was surprised, but not nearly as surprised as waking up with my head sewn to the carpet.
