Being saucy, I am put outside room (8)
I believe the answer is:
impudent
'being saucy' is the definition.
('impudent' can be a synonym of 'saucy')
'i am put outside room' is the wordplay.
'i am' becomes 'I'm' (contraction).
'outside' indicates putting letters inside (some letters go outside others).
'room' becomes 'den' (den is a kind of room).
'put' enclosing 'den' is 'pudent'.
'im'+'pudent'='IMPUDENT'
(Other definitions for impudent that I've seen before include "impolite" , "Rude" , "Audacious" , "Saucy" , "Cheeky, disrespectful" .)
