Why “chuchotage” is a great word
CHUCHOTAGE — [Noun] The practice of whispering a simultaneous interpretation to one or a very few listeners. From French chuchotage, meaning "whispering", from the verb chuchoter ("to whisper"). Unlike simultaneous interpreting, which employs booths for a full audience, or consecutive interpreting, which requires the speaker to pause, chuchotage is an intimate, equipment-free art of real-time fidelity. It is the low murmur beside a diplomat's ear in a treaty negotiation, the confidential breath translating a surgeon's instruction, and the hushed cascade of words in the back row of a lecture hall—a fragile, parallel stream of meaning spun on the very air it dares not disturb.
