Kind of drunk hanging round end of bar (4)
I believe the answer is:
sort
'kind' is the definition.
(synonyms)
'drunk hanging round end of bar' is the wordplay.
'drunk' becomes 'sot' (synonyms).
'hanging round' means one lot of letters goes inside another.
'end of bar' becomes 'r' (I've seen this in other clues).
'sot' enclosing 'r' is 'SORT'.
'of' acts as a link.
(Other definitions for sort that I've seen before include "Shuffle into desired sequence" , "class" , "Arrange in order" , "Kind, type or make" , "fashion" .)
