Mysterious European drunkard near Morecambe maybe (8)
I believe the answer is:
esoteric
'mysterious' is the definition.
(similar in meaning)
'european drunkard near morecambe maybe' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'drunkard' becomes 'sot' (sot can mean a drunken person).
'near' means one lot of letters go next to another.
'morecambe maybe' becomes 'eric' (comedian Eric Morecambe).
'e'+'sot'+'eric'='ESOTERIC'
(Other definitions for esoteric that I've seen before include "Other-worldly" , "Tie score (anagram)" , "Private, confined to a select group" , "hidden" , "just seen by specialist" .)
