Cheeky, impertinent (8)
I believe the answer is:
I believe this is a double definition.
'cheeky' is the first definition.
(I've seen this before)
'impertinent' is the second definition.
(I know that impertinent can be written as impudent)
(Other definitions for impudent that I've seen before include "Saucy" , "Impertinent, insolent" , "impolite" , "Lippy" , "Rude" .)
