Exhibitor in the wet? (6)
I believe the answer is:
shower
I believe this clue is a double definition.
'exhibitor' is the first definition.
(I know that exhibitor can be written as shower)
'the wet?' is the second definition.
(thesaurus)
'in' is the link.
(Other definitions for shower that I've seen before include "Useless people" , "Brief spell of precipitation" , "Short outbreak of rain" , "Pelt" , "detestable group" .)
