Humour from Switzerland (3)
I believe the answer is:
wit
'humour' is the definition.
(I know that humour can be written as wit)
'from switzerland' is the wordplay.
'from' indicates the answer is hidden within the clue.
'WIT' can be found hidden inside 'switzerland'.
(Other definitions for wit that I've seen before include "Mental ability" , "Ingenuity; wag" , "Ingenuity or verbal fun" , "Drollness, humour" , "Quickness at clever remarks" .)
