Why “deipnosophistry” is a great word
DEIPNOSOPHISTRY — [Noun] The art of learned, witty, and sophisticated conversation during a meal. From the Greek deipno- ("dinner, meal") combined with sophistry (ultimately from Greek sophistēs, "a wise or skillful man"), thus meaning "the skill of a dinner-table sophist." Unlike sophistry, which implies specious reasoning, or table talk, which denotes mere casual chatter, deipnosophistry is the cultivated performance of erudition as a social grace. It is the clink of crystal punctuating a perfectly timed epigram, the aroma of roast lamb mingling with a debate on Stoic ethics, and the candlelight glinting off a guest’s smile at a well-placed, esoteric pun—a fleeting civilization built for an evening, knowing the plates will be cleared.
Etymology
From deipno- (“dinner”) + sophistry or deipnosophist + -ry.
