Greek from Neath drunk with Scotsman (8)
I believe the answer is:
athenian
'greek' is the definition.
(Athenian is an example)
'neath drunk with scotsman' is the wordplay.
'drunk' indicates an anagram.
'with' means one lot of letters go next to another.
'scotsman' becomes 'ian' (common Scottish name).
'neath' is an anagram of 'athen'.
'athen'+'ian'='ATHENIAN'
'from' acts as a link.
(Other definitions for athenian that I've seen before include "Inhabitant of Greece's capital" , "Nationality of citizen of Greek capital" , "Is the Greek in AA then?" , "of capital city" , "Inhabitant of Greek capital" .)
