Phil Wang and Susie Dent
BBC Radio 4, 18 February 2024 (pilot), 31 October 2024 to present (series)
According to the BBC,
During the show, three contenders put forward their ideas for new words. There's a bit of debate, and Susie chimes in with facts about the word - or similar words. It's a bit like her "Origin of Words" segment on Countdown mixed with a dinner party. Best new word - as judged solely by Phil Wang - wins an Unspeakable bookmark.
Because there wasn't enough material to fill a half hour, the contestants also groused at the most over-worked words, and a few contributions from the audience. Unspeakable felt like a great 15 minute discussion, stretched out to fill a half-hour slot. If commissioned for a series, we'd hope for some extra rounds.
