Comedians Josh Widdicombe and Helen Keen, Dictionary Corner's Susie Dent and classics scholar Natalie Haynes vie for wordy supremacy under the watchful eye of chair Gyles Brandreth.

Lexicographer Susie Dent admits to the words she finds most difficult to spell; science lover Helen Keen grumpily dismantles the portmanteau word 'murse'; Natalie Haynes works out what 'kyacting' is, and does some to boot; while Josh Widdicombe tries to ban the word 'chilllax'.

The panel also guess what some foreign words which have no direct equivalent in English: the Caribbean Spanish word 'cotisuelto; the Welsh phrase 'glas wen'; the German word 'Kummerspeck' and the Central American Spanish word 'achaplinarse'.

Finally they unearth some archaic phrases from the 1870s: 'gigglemug', 'Jeremiah-mongering', 'back row hopper' and 'robbing the barber'.
