Obscure English drunk at Morecambe? (8)
I believe the answer is:
esoteric
'obscure' is the definition.
(requiring specialist knowledge or special interest)
'english drunk at morecambe?' is the wordplay.
'english' becomes 'e' (abbreviation).
'drunk' becomes 'sot' (both can mean someone who drinks too much).
'at' means one lot of letters go next to another.
'morecambe?' becomes 'eric' (comedian Eric Morecambe).
'e'+'sot'+'eric'='ESOTERIC'
(Other definitions for esoteric that I've seen before include "Hard to understand" , "of rarefied tastes" , "Abstruse; secret" , "Private, confined to a select group" , "I set core up to be mysterious" .)
