This episode we hear Hugh Dennis's word for decision fatigue, Katy Wix's coinage for when you find yourself stuck telling a story in public to break an awkward silence, and Jess Fostekew's word for that nuggety squashed sock you find stuck inside a duvet cover.

Ever struggled to find the right word for a feeling or sensation? Unspeakable sees comedian Phil Wang and lexicographer Susie Dent invite celebrity guests to invent new linguistic creations, to solve those all too relatable moments when we're lost for words.
