Overbearing drunk had to accept sorry end (4-6)
I believe the answer is:
high-handed
'overbearing' is the definition.
(thesaurus)
'drunk had to accept sorry end' is the wordplay.
'drunk' becomes 'high' (I've seen this before).
'to accept' means one lot of letters goes inside another.
'sorry' is an anagram indicator (letters in a sorry state).
'end' is an anagram of 'nde'.
'had' enclosing 'nde' is 'handed'.
'high'+'handed'='HIGH-HANDED'
(Other definitions for high-handed that I've seen before include "Overbearing" , "Domineering, inconsiderate" .)
