Irish comedian Ed Byrne, Tasmanian stand up and art expert Hannah Gadsby, punmaster general Milton Jones and classics boffin Natalie Haynes join chair Gyles Brandreth for the panel game for word fans.

The Letter of the week is 'Z'. Ed Byrne is asked what a 'Zigger-Zagger' is; Natalie 'a Zombie Title'; Hannah is asked about the German expression 'zugzwang', and Milton is as what he thinks a 'zafty' might be.

Also on the show the panellists are asked to coin their own topynyms. Tune in to find out what Natalie meant by Hackney and Alaska. And what did Milton imagine you'd find in Antandectwerp?

In a round called 'Eat It Or Not' the panel have to guess whether the foreign words hurled at them by Gyles are edible or not.

They then get a chance to add their own new word to the dictionary. Milton's is 'parashambles'; Hannah's is 'shelve'; Natalie's is 'fraudience' and Ed's is 'cheerbleeders'. But what are their definitions?

Finally the panellists are asked to delve into 'A Dictionary of Americanisms' from 1848. The phrases they are asked to muse on are: 'a hurra's nest'; a 'talking iron'; 'wamble-cropped' and 'shooting your grandmother'.
