Rude, impolite (3-8)
I believe the answer is:
ill-mannered
This clue is a double definition.
'rude' is the first definition.
(I know that rude can be written as ill-mannered)
'impolite' is the second definition.
(similar in meaning)
(Other definitions for ill-mannered that I've seen before include "Boorish - uncivil" , "Rude - uncouth" , "Rude, discourteous" .)
