Liberal excluded is hard and coarse (7)
I believe the answer is:
loutish
'coarse' is the definition.
(thesaurus)
'liberal excluded is hard' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'excluded' becomes 'out' (I've seen this in another clue).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'l'+'out'+'is'+'h'='LOUTISH'
'and' acts as a link.
(Other definitions for loutish that I've seen before include "Boorish" , "Ill-mannered and coarse, behaviour say" , "uncouth and aggressive" , "like a hooligan" .)
