Being saucy I am put outside the room (8)
I believe the answer is:
impudent
'being saucy' is the definition.
('impudent' can be a synonym of 'saucy')
'i am put outside the room' is the wordplay.
'i am' becomes 'im'.
'outside' means one lot of letters goes inside another.
'the room' becomes 'den' (den is a kind of room**).
'put' placed around 'den' is 'pudent'.
'im'+'pudent'='IMPUDENT'
(Other definitions for impudent that I've seen before include "Cheeky, disrespectful" , "impolite" , "Audacious" , "Saucy" , "Impertinent, insolent" .)
